Spain Ministry of Health / CCAES report (10 Aug; reported by ConSalud 11 Aug 2026): six close contacts are identified around the imported Franco-Argentine Andes-virus case. Four newly identified contacts travelled on Santiago de Chile–Madrid (18 Jul) or Madrid–Bordeaux (19 Jul); all six contacts were asymptomatic and home-quarantining, with tests for the four new contacts pending. The patient and two household contacts tested PCR-negative; the patient was discharged from epidemiological follow-up and returned to France, while the household contacts remain isolated to complete 42 days. CCAES assesses risk as very low for healthcare workers and extremely low for Spain’s general population. No established MV Hondius link; its final baseline remains 13 cases (12 confirmed, 1 probable), 3 deaths, outbreak over.
Argentina Ministry of Health BEN No. 820 (SE30, published 10 Aug 2026): the national bulletin records 53 cumulative confirmed hantavirosis cases in 2026 through SE30, compared with a 2022–2025 median of 38. The cumulative count is up one from BEN No. 819’s 52. The year-to-date trend is classified as increasing (en aumento), while the latest four weeks are below expected (por debajo de lo esperado). No death count or new guidance was reported; figures are preliminary and revisable. Endemic Argentine surveillance, unrelated to the contained MV Hondius outbreak (final baseline 13 cases — 12 confirmed, 1 probable — and 3 deaths).
Cooperativa, citing ISP and O’Higgins Seremi (7 Aug 2026): ISP confirmed hantavirus in an 11-year-old girl in Rengo who died. A preliminary investigation identifies travel to Bolivia as the probable exposure; O’Higgins reports 7 confirmed cases and 3 deaths in 2026. No arithmetic change is made to Chile’s official national SE30 total of 48 confirmed cases through 1 Aug: whether this case is included is not yet known, and a later national bulletin is needed to reconcile the figures. Separate endemic/imported Chile surveillance, unrelated to the contained MV Hondius outbreak.
Chile Ministry of Health — Epidemiological Bulletin SE30 (Aug 2026): Chile reports 48 confirmed hantavirus cases in 2026 through epidemiological week 30 (ending 1 Aug 2026), incidence 0.24 per 100,000 — up two from the previous 46-case baseline. Figures are official surveillance and may be revised; no updated death count was verified, so none is inferred. Endemic Chile surveillance, unrelated to the contained MV Hondius outbreak (final baseline 13 cases — 12 confirmed, 1 probable — and 3 deaths).
French Official Journal (8 Aug 2026): Decree No. 2026-751 authorizes quarantine for contacts assessed to face a serious Andes-virus infection risk and isolation for confirmed infections associated with the imported case, for up to 42 days from the last at-risk contact; prefectural authorities may enforce measures when urgent or necessary. This is a legal public-health management measure, not evidence of onward transmission. France's Health Ministry continues to assess transmission risk as very low; contact tracing continues and no MV Hondius link is established.
France Ministry of Health (7 Aug 2026): the risk of onward transmission from the imported Andes virus case is judged very low, concentrated among the closest and most prolonged contacts. The Franco-Argentine tourist, isolated with family in Galicia, Spain, is no longer symptomatic; the potential infectious window is assessed as 18–28 July and the diagnostic viral load was very low. Contact tracing continues. The case remains imported with no established link to the contained MV Hondius outbreak; risk is described as very limited rather than absent, and that outbreak's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Doherty Institute / Cumming Global Centre (6 Aug 2026): the Centre funded two early-stage Andes hantavirus therapeutic projects. University of Queensland researchers will develop bi-specific nanobody candidates intended to progress toward preclinical testing; Doherty Institute researchers will develop a CRISPR-Cas13 mRNA approach beginning in cell models and then animal models. Funded early-stage/preclinical research only: these are not approved or available treatments, not clinical evidence in people, and not an outbreak count or status change.
Argentina Ministry of Health BEN No. 819 (SE29, published 4 Aug 2026): the national bulletin records 52 cumulative confirmed hantavirosis cases in 2026 through SE29, compared with a 2022–2025 median of 37. The cumulative count is unchanged from BEN No. 818. The year-to-date level remains above expected, while the latest four weeks are within expected. Figures are preliminary and revisable. Endemic Argentine surveillance, unrelated to the contained MV Hondius outbreak; no change to its final 13 cases and 3 deaths.
Radio Santa María / Seremi de Salud Aysén (6 Aug 2026): Hospital Guillermo Grant Benavente's clinical laboratory confirmed two new hantavirus cases—the 62-year-old woman and her 17-year-old granddaughter transferred from Coyhaique. Aysén reports five confirmed cases in 2026, including one death earlier this year. Endemic Chile context, unrelated to the contained MV Hondius outbreak; no national Chile total is inferred, and the outbreak's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Tatarstan, Russia (31 Jul): two regional reports citing the deputy head of Tatarstan’s Rospotrebnadzor office say 324 hemorrhagic fever with renal syndrome (HFRS) cases were registered in January–July 2026, nearly double the same period in 2025 and up from 190 reported in late June. Officials said rodent infection and abundance exceed long-term averages and described the rise as part of a cyclical endemic increase. Regional surveillance context only: not a declared epidemic, unrelated to the contained MV Hondius outbreak, and no change to its final 13 cases and 3 deaths.
Radboudumc (31 Jul 2026): an internal review found that 12 staff — 7 nurses and 5 laboratory workers — may have been avoidably exposed to Andes virus through blood or urine while caring for an MV Hondius-linked patient; possible exposure does not mean infection, and no staff infection occurred. The review identified system factors rather than individual blame and recommends precautionary handling and HLIU admission for novel severe infections while protocols are developed. Institutional review only, not new WHO/RIVM guidance; all staff were out of quarantine by 22 Jun and the patient was discharged 20 May. No outbreak count or status change: WHO’s final baseline remains 13 cases (12 confirmed, 1 probable), 3 deaths, outbreak over.
Chile Ministry of Health (28 Jul 2026): Minsal declared Chile's first hantavirus Health Alert from Atacama through Magallanes, valid through 31 July 2027. Through the prior week, 2026 surveillance recorded 46 infections and 18 deaths (39% case-fatality proportion), versus 44 infections and 8 deaths (18%) in 2025. This is a preventive and preparedness measure for an endemic disease, not a declaration of an epidemic or overwhelmed health care. It is unrelated to the contained MV Hondius event; WHO's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
University of Queensland / Nature Communications (29 Jul): preclinical, host-targeted antiviral research reports that inhibiting the human enzyme NMT1 reduced viral infection in cell-culture (in vitro) tests of SARS-CoV-2, RSV and vesicular stomatitis virus — by about half after one day and up to about 90% after two days. Hantavirus itself was NOT tested; researchers only suggest the host-targeted mechanism could potentially apply to a range of viruses including hantavirus. Preclinical laboratory research only: not an approved hantavirus treatment, not clinical evidence in people, and not an outbreak count or status change; WHO's final MV Hondius baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Tres Arroyos Municipal Health Secretariat / LU24 (26 Jul): an official municipal communiqué says Tres Arroyos district has recorded two confirmed hantavirus cases in 2026, in February and July; Health Region I has three cases total, including one from another municipality. Epidemiological investigations linked both local cases to wild-rodent exposure, with no infections among close contacts and no evidence of person-to-person transmission in the district. Variant typing for the July case remains pending. These local figures may already be included in Argentina BEN No. 817's 51 confirmed cases through SE27 and must not be added to that national total. Unrelated to the contained MV Hondius outbreak; no change to its final 13 cases and 3 deaths.
RIVM (23 Jul 2026): more people than in previous years have fallen ill from Puumala orthohantavirus in Twente, the Netherlands, in 2026; this infection averages about 15 cases a year, and many affected people required temporary hospital admission. Reported exposures commonly involved nature, forests or meadows, or dust from mouse droppings while cleaning or sweeping sheds. A mast year and increased rodent abundance are one possible explanation. Puumala virus is different from Andes virus; this event is unrelated to the contained MV Hondius outbreak and does not change its final baseline of 13 cases (12 confirmed, 1 probable) and 3 deaths.
Canal Siete / regional epidemiology (23 Jul): a confirmed hantavirus patient, a rural worker in Tres Arroyos, Buenos Aires Province, remained in critical/guarded condition with slight improvement; strain testing was pending to determine whether this is Andes virus. The patient remained isolated under respiratory protocol; close family contacts were under daily symptom monitoring for the incubation window, with none symptomatic at report time, and environmental teams were investigating the rural workplace. This regional case is unrelated to the contained MV Hondius outbreak, with no change to its final 13 cases and 3 deaths. Argentina national cumulative placement awaits a later official bulletin; do not infer whether this case is already included in BEN No. 817's 51 confirmed 2026 cases through SE27.
BBC News Ukraine (23 Jul 2026): a Lviv regional laboratory confirmed hantavirus RNA by PCR in a 53-year-old Stryi resident with hemorrhagic fever with renal syndrome. Symptoms began 12 July and he was hospitalized 15 July. He had recently visited Croatia's Makarska Riviera and mountainous Ivano-Frankivsk region, but where and how infection occurred remain unknown; an epidemiological investigation continues. BBC cites Ukraine's Public Health Center as reporting 63 infections in the first three months of 2026 and 436 in 2025. Global context only, unrelated to the contained MV Hondius outbreak; its final count remains 13 cases and 3 deaths.
Argentina Ministry of Health BEN No. 817 (SE27, published 20 Jul 2026): SE27 bulletin records 51 confirmed hantavirosis cases in 2026 through SE27, versus a 2022–2025 median of 34; annual status is above expected, while the latest four weeks are below expected. SE26 also recorded 51, so there is no week-over-week increase; figures are provisional and revisable. Endemic Argentine surveillance, unrelated to the contained MV Hondius event (final: 13 cases, 3 deaths).
Reuters / AP (21 Jul): Venezuela's Health Ministry reported that three laboratory-confirmed hantavirus patients died in the rural Miranda municipality of Anzoátegui state; two additional deaths of health workers in Barinas are suspected, under investigation and unlinked. The ministry reports no evidence of person-to-person transmission in Venezuela and calls these isolated events that do not represent a general risk to the community. Regional news context only: explicitly unrelated to the contained MV Hondius outbreak and no change to its 13 cases (12 confirmed, 1 probable) and 3 deaths.
CIDRAP / JAMA Neurology review (20 Jul): a research review examines how hantavirus infection can, uncommonly, cause serious neurologic complications — including headache, delirium and seizures, and rarely more severe neurologic effects; long-term neurologic effects remain understudied and there is still no FDA-approved antiviral treatment or licensed vaccine. Research/clinical-context only: not a new outbreak case or count change; WHO's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Argentina Ministry of Health / ANLIS Malbrán (16 Jul): Argentina's national reference laboratory says Malargüe, Mendoza rodents tested negative for hantavirus antibodies; Tierra del Fuego rodents carried a different hantavirus variant and were ruled out as the source linked to the MV Hondius event. ANLIS also sent Andes-virus diagnostic materials to laboratories in eight additional countries. Official source-investigation and laboratory-capacity update only: no new human case or MV Hondius count change; WHO's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
ECDC (9 Jul): ECDC's Andes hantavirus surveillance page formally acknowledges that the 2026 MV Hondius Andes virus outbreak has been contained and declared over by the World Health Organization on 2 July 2026, and says the page is no longer being regularly updated; outbreak totals remain 13 cases (12 confirmed, 1 probable) and 3 deaths. Official post-outbreak closure acknowledgement that aligns with WHO DON611 (2 Jul) and supersedes ECDC's 17 June active-event surveillance; no count change.
CDC Emerging Infectious Diseases (9 Jul): A retrospective study of samples from 371 chronically ill patients collected from 2004–2018 in northwestern Italy found hantavirus IgG in 7.3%; PUUV-neutralizing antibodies were confirmed in 10 tested cases. The findings suggest previously unrecognized local circulation but cannot establish infection timing, symptom linkage, or current incidence. Research context only: unrelated to MV Hondius and no change to outbreak totals (13 total, 12 confirmed, 1 probable, 3 deaths).
Kommersant / Udmurtia Rospotrebnadzor (3 Jul): Udmurtia's regional Rospotrebnadzor reports 259 hemorrhagic fever with renal syndrome (HFRS) cases in January–June 2026, up from 80 in the same period of 2025; 166 were reported in June and incidence was 18.05 per 100,000. Reported exposures were household-related (49.5%), garden/dacha (26.1%), and forest activities (24.3%). The report attributes exposures to rodent-associated settings and does not report person-to-person transmission. Endemic regional Russia surveillance context (surfaced by ProMED 5 Aug), unrelated to the contained MV Hondius Andes-virus outbreak and not a change to its final 13 cases (12 confirmed, 1 probable) and 3 deaths.
WHO DON611 (2 Jul): WHO says the MV Hondius Andes hantavirus outbreak no longer poses a public-health risk and no further related transmission is expected after all identified contacts completed the 42-day follow-up period without additional secondary cases. As of 2 Jul, WHO reports 13 linked cases including 3 deaths: 12 laboratory-confirmed and 1 probable; 8 of 10 hospitalized cases have recovered and been discharged, and 2 remain in treatment. WHO also reports 317 high-risk contacts completed quarantine/monitoring and 336 low-risk contacts completed self-monitoring. Official outbreak-containment/status update; it updates closure/status while keeping the case baseline at 13 cases, 12 confirmed, 1 probable, and 3 deaths.
ProMED Mail (1 Jul): HANTAVIRUS - ARGENTINA (27): Santa Fe authorities confirmed the first hantavirus case this year in a rural area of Santa Fe Province, initiated containment protocols and an environmental investigation, and reminded the public to use hygiene measures that reduce rodent contact. News-context only: this is not an MV Hondius count source and does not change the ECDC/RIVM baseline of 13 cases (12 confirmed, 1 probable) and 3 deaths.
ProMED Mail (29 Jun): HANTAVIRUS - ARGENTINA (26): a woman in San Carlos de Bariloche, Río Negro, died from hantavirus; the report notes possible human-to-human transmission for the regional strain, alongside usual rodent-associated transmission, and advises prompt medical care if symptoms appear after outdoor activity or contact with a confirmed case. News-context only: not an MV Hondius count source or outbreak-total change.
Buenos Aires Times / AFP (29 Jun): Argentina's Health Ministry and ANLIS-Malbrán report hantavirus detection in five Abrothrix rodents captured in Tierra del Fuego, but the viral variant differs from the human MV Hondius outbreak variant and the analysed rodents were ruled out as the infection source linked to that event. Source-investigation context only: no new human case or MV Hondius count change; the source of the first patient's infection remains under investigation and the ECDC/RIVM baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
PHAC / Canada.ca (29 Jun): PHAC has concluded its hantavirus response; on 17 May 2026 PHAC confirmed one Andes hantavirus case in Canada by laboratory testing; as of 26 Jun 2026 all contacts in Canada who may have been exposed to Andes hantavirus linked to MV Hondius have completed self-isolation and monitoring periods; the infected individual has recovered; overall risk to the general population in Canada remains low. Canada response/monitoring-completion update only: no new case-count change and no global outbreak-over declaration; the ECDC/RIVM baseline remains 13 total cases (12 confirmed, 1 probable) and 3 deaths.
DPA/Yahoo / WHO-Tedros (29 Jun): WHO Director-General Tedros Adhanom Ghebreyesus said all contacts of two MV Hondius-linked cases identified in South Africa have completed follow-up with no additional cases, and quarantine/follow-up periods are also complete for everyone in Spain and the Netherlands, including MV Hondius crew. As of 25 Jun, 30 contacts were still under follow-up; the total remains 13 cases including 3 fatalities, the situation remains stable, and the outbreak is nearing its end. Outbreak-status/follow-up context only: not a formal global outbreak-over declaration and no ECDC/RIVM/WHO count change.
Yukon News / Black Press (25 Jun): B.C. health officials say the Yukon MV Hondius cruise-ship passenger who tested positive for hantavirus has been discharged from a B.C. hospital and is still recovering. The case was confirmed in mid-May after mild symptoms and involved the Andes strain; their partner tested negative and remains asymptomatic, with quarantine scheduled to finish 26 Jun. The other two passengers isolating in B.C. ended quarantine on 21 Jun and remained asymptomatic. Clinical/status update for an existing Canadian/Yukon confirmed case only; no official count change and the ECDC/RIVM baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
HHS (24 Jun): federal public-health response to the MV Hondius hantavirus exposure event has concluded; the final 42-day monitoring period ended on 21 Jun at 2 p.m. EDT, no individuals in the United States remain under public-health monitoring for hantavirus exposure, and no positive U.S. case or sustained U.S. transmission was identified. U.S. response/monitoring-completion update only: not a global outbreak-over declaration and no change to the ECDC/RIVM baseline of 13 cases (12 confirmed, 1 probable) and 3 deaths.
France 24 / WHO (24 Jun): WHO chief Tedros Adhanom Ghebreyesus said more than 650 MV Hondius Andes-hantavirus contacts were identified and followed by health authorities in 33 countries and territories; all but 54 have completed quarantine, and the remaining contacts are scheduled to complete quarantine by 2 Jul. WHO will consider the outbreak over if no further cases are reported by then. Outbreak-end timing/status context only: it is not formally over yet and does not change the ECDC/RIVM baseline of 13 total cases (12 confirmed, 1 probable) and 3 deaths.
CIDRAP (24 Jun): newly confirmed CIDRAP report says an international public-health response — medical evacuations, contact tracing, quarantine and laboratory monitoring — helped contain the MV Hondius Andes hantavirus outbreak. Investigators identified 188 high-risk contacts across seven countries; quarantine was lifted for 61 Netherlands passengers/crew on 18 Jun and for American passengers on 21 Jun, with the last monitored person expected to complete quarantine on 2 Jul. As of 18 Jun, all 13 cases were confined to ship passengers/crew, no community transmission was detected, ongoing community transmission was unlikely, and there is no ECDC/RIVM count change (13 cases, 3 deaths).
CDC Newsroom transcript (24 Jun): CDC says this week marks the successful conclusion of CDC's public health response to the MV Hondius hantavirus outbreak; by Sunday all U.S. citizens with potential Andes virus exposure had completed 42-day monitoring, everyone is home safe, and none developed hantavirus disease. Official U.S. response/monitoring-completion update only: CDC scientific work continues, including Argentina rodent trapping/testing by two CDC disease ecologists; preliminary identified rodents were negative and the source remains under investigation. This is not a global outbreak-over declaration and does not change the ECDC/RIVM baseline of 13 cases (12 confirmed, 1 probable) and 3 deaths.
ABC Australia / RNZ (23 Jun): four Australian citizens, one Australian permanent resident and one New Zealander linked to MV Hondius were released from Perth/Bullsbrook quarantine after 42 days; ABC reports all six remained well and consistently tested negative, and RNZ reports Australian officials were confident they were free of the virus.

U.S. quarantine-completion / lessons-learned context only: not a new infection or count change; CDC's 22 Jun situation summary says no U.S. hantavirus disease cases occurred as a result of this outbreak, and the official ECDC/RIVM baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Demócrata/EFE (20 Jun): Spain's Health Ministry says management of the MV Hondius-linked hantavirus outbreak in Spain has concluded after quarantines ended, follow-up PCRs were negative, and the two positive cases were discharged. Spain follow-up-completion context only; this is not a global outbreak-over declaration and there is no official ECDC/RIVM case-count change: baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Oceanwide Expeditions (20 Jun): operator says all remaining MV Hondius crew members quarantined in the Netherlands after Rotterdam/Tenerife disembarkation completed quarantine on Thu 18 Jun 2026 and are returning home; no health complaints or further hantavirus cases were reported among these individuals, beginning-of-week tests were negative, and GGD maintained daily contact. Operational monitoring-completion context only; no case-count change and the current official ECDC/RIVM baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
GMA News / Philippines DMW (20 Jun): Department of Migrant Workers Secretary Hans Leo Cacdac announced that 38 Filipino MV Hondius crew members returned to the Philippines after completing quarantine in the Netherlands; they had previously tested negative before quarantine, and this repatriation/monitoring-completion update does not change the official ECDC/RIVM outbreak baseline of 13 cases (12 confirmed, 1 probable) and 3 deaths.
WHO/Tedros (19 Jun): with no new MV Hondius-linked hantavirus cases reported in over three weeks and no new deaths since 2 May, WHO says the situation remains stable. AFP/MedicalXpress reports almost all passengers and crew quarantined in the Netherlands are now allowed to return home; context only, no formal all-clear/end declaration and no change to the 13-case baseline (12 confirmed, 1 probable, 3 deaths).
Eurosurveillance (18 Jun): peer-reviewed outbreak investigation summarises the MV Hondius-linked Andes orthohantavirus event at 13 cases as of 18 Jun (12 confirmed, 1 probable; CFR 23%), involving passengers (10/121; 8%) and crew (3/61; 5%) across 23 nationalities with medical evacuation, repatriation and coordinated contact tracing/quarantine follow-up. High-signal investigation context only; it does not change the ECDC/RIVM count baseline.
ECDC (17 Jun): official update last updated 17 June 2026 at 13:55 reports 13 cases in total (12 confirmed and 1 probable) in the MV Hondius-linked Andes hantavirus outbreak; some identified contacts have completed quarantine and others are expected to do so in the coming days, while public-health authorities continue monitoring contacts. This supersedes the older 11/12 Jun ECDC baseline for current official count/status but does not change case or death totals.
RIVM official update (18 Jun): almost all Netherlands-quarantined MV Hondius passengers and crew ended their 42-day quarantine on 18 June after release testing for Andes virus; all release tests were negative. One close contact of a later-hospitalised Andes-virus patient remains in quarantine longer. RIVM reports the outbreak total as 13 people ill and 3 deaths; no new case-count change.
CNN (16 Jun): RFK Jr. ordered an exposed MV Hondius passenger to remain in federal quarantine in Nebraska despite CDC/federal health-expert clearance to return home to Florida, CNN reports. This is a U.S. quarantine-policy/monitoring update for an exposed passenger, not a new infection, symptom report, or official case-count change.
Demócrata/EFE (16 Jun): Spain says the last patient remaining hospitalized at Central Defense Hospital Gómez Ulla due to MV Hondius-linked hantavirus infection was discharged Tuesday and is now at home; no MV Hondius outbreak patients remain admitted there. Clinical-outcome/status context for existing Spain cases only; no new infection and no official WHO/ECDC/CDC case-count change.
Health Policy Watch (16 Jun): after a WHO EPI-WIN briefing, Dutch, Spanish and Swiss clinicians reported using slightly different discharge criteria for MV Hondius-linked Andes hantavirus patients, and none required a negative blood PCR because blood can remain positive for months. Netherlands used two negative saliva tests; Spain required two negative throat/oropharyngeal and urine PCRs; U.S. home monitoring depends on isolation circumstances and PPE precautions. IPC/quarantine implementation context only; no WHO/ECDC/CDC case-count change.
WHO EPI-WIN (16 Jun): WHO is hosting an official IPC/guidance-event webinar on hantavirus/Andes virus infection prevention and control, focused on isolation, safe discharge, discontinuing transmission-based precautions, and quarantine implementation. WHO notes operational gaps remain around discharge criteria, de-escalation and quarantine settings; it says the MV Hondius outbreak involved human-to-human transmission but exact modes remain under investigation, and that ANDV does not behave like highly transmissible airborne diseases such as measles. Context only: no case-count change.
WHO (12 Jun): WHO says 21 countries launched NAVIS, a coordinated Andes-virus natural-history research initiative after the MV Hondius outbreak, to study transmission dynamics, incubation periods, immune responses, viral kinetics and severe-disease determinants using harmonized ISARIC-style data/sample collection. Research-preparedness context only: no approved vaccine/treatment and no WHO/ECDC/CDC case-count change.
NBC News (11 Jun): CDC and Florida health officials are at odds over MV Hondius passenger home-quarantine surveillance; NBC reports Florida is not planning CDC-requested round-the-clock surveillance for an exposed passenger seeking to leave the Nebraska National Quarantine Unit and complete quarantine at home. U.S. quarantine-implementation/policy dispute: 18 Americans were repatriated; as of the report 10 had left Nebraska for home-state surveillance and 8 remained at NQU; all Americans aboard tested negative/no symptoms; 42-day period scheduled to end 22 Jun. No change to the ECDC count baseline (13 cases, 12 confirmed, 1 probable, 3 deaths as of 11 Jun).
AP/ABC (11 Jun): State Department committed $750,000 to charter a yacht to evacuate one asymptomatic American citizen who had been aboard MV Hondius from remote Pitcairn Island toward Easter Island/Chile after French Polynesia declined admission; logistics/consular response for a potentially exposed but asymptomatic person, no official case-count change.
ECDC CDTR Week 24 (12 Jun): for the South Atlantic cruise-ship Andes virus outbreak, ECDC reports that as of 11 Jun there are still 13 cases (12 confirmed, 1 probable) and 3 deaths, with no new deaths since the previous update; one previously probable Tristan de Cunha-exposed case was laboratory-confirmed on 10 Jun (UKHSA/WHO). Sequencing from some positive cases showed high genetic similarity, likely indicating an initial zoonotic spillover followed by human-to-human transmission. This CDTR source does not change case/death totals; EU/EEA general-population risk remains very low and the likelihood of ANDV affecting the SoHO donor population is assessed negligible.
News-Medical/UTMB (11 Jun): UTMB reports a Lancet study (DOI 10.1016/S0140-6736(26)01124-4) of a single-dose mRNA Andes hantavirus vaccine candidate showed 100% protection in an animal challenge model and protective antibodies by 14 days; UTMB says NIH-supported work is being fast-tracked toward human trials. Research context only: preclinical/animal-model data, no approved hantavirus vaccine or specific treatment yet, and no WHO/ECDC/CDC outbreak-count change.
Federal Register (10 Jun): CDC proposes new “2026 Andes Hantavirus Cruise Passenger and Traveler Contact Monitoring” project under Docket CDC-2026-1024; 60-day public comment to 10 Aug 2026 (OMB 0920-0218, DGMH/NCEZID). No change to WHO/ECDC outbreak count (13/3).
Reuters (9 Jun): three additional U.S. MV Hondius hantavirus-exposed passengers left the Nebraska National Quarantine Unit on 9 June after four weeks of monitoring; eight of the original 18 have now returned home (five the week of 2 June, three on 9 Jun) and ten remain in Omaha, all continuing self-monitoring under local/state health departments for the rest of the 42-day incubation period; no change to the 13-case / 3-death WHO/ECDC outbreak count.
CBC (8 Jun): B.C. provincial health officer says the Canadian who tested positive for hantavirus after evacuating MV Hondius (a Yukon traveller in their 70s) has recovered and was discharged from hospital late last week; three other contacts remain asymptomatic under 42-day quarantine; clinical-outcome update for an existing confirmed case, no WHO/ECDC count change.

Buenos Aires Times/AFP (12 Jun): Argentina Health Ministry says the Mendoza source investigation (ANLIS-Malbrán + CDC experts, >250 traps around Malargüe) did not find Oligoryzomys longicaudatus, the main known Andes virus reservoir in much of Patagonia; another rodent species may have been captured and further tests are underway. Source-investigation context only: no change to official outbreak counts.
Xinhua/China.org (5 Jun): Spain says the first Spanish MV Hondius patient, a 70-year-old man, was discharged after three symptom-free days and two negative PCR tests; follow-up continues, second Spanish positive had mild symptoms, 12 other Spanish passengers remain negative/quarantined; no count change.
Australian CDC / CDI Situation Report 5 (4 Jun): confirms WHO's 13-case, 3-death outbreak count (CFR 23%); ANDV added to Australia's Biosecurity Listed Human Diseases (12 May) and made nationally notifiable for 6 months (22 May); six repatriated Australian passengers still in quarantine; no case-count change.
AP (4 Jun): researchers in Chile, Argentina and the U.S. are pursuing hantavirus drugs and vaccines; no approved treatments or vaccines exist for the cruise-ship Andes-virus response, so this is research context, not new clinical guidance.
The Straits Times (7 Jun): Singapore CDA says two Singapore MV Hondius residents completed 42-day quarantine and were released 6 Jun after testing negative for hantavirus including Andes virus; last exposure was an Apr 25 flight shared with a confirmed case; public risk low; monitoring/status context, no official case-count change.
CDC FAQ (9 Jun): CDC says the MV Hondius Andes-virus outbreak is not like COVID-19; Andes virus does not spread easily person-to-person and usually requires close/prolonged contact with a symptomatic person or body fluids. Symptoms can appear 4–42 days after exposure; testing is for symptomatic people with known exposure; there is no specific treatment beyond supportive care. CDC says pandemic risk and U.S. public/traveler risk remain extremely low; no WHO/ECDC count change.
OHA (2 Jun): Oregon MV Hondius passenger returned home from Nebraska on 1 Jun and remains quarantined through 21 Jun; OHA says Oregon infection risk remains extremely low with no general-public transmission concerns.

Spain Ministry of Health / CCAES report (10 Aug; reported by ConSalud 11 Aug 2026): six close contacts are identified around the imported Franco-Argentine Andes-virus case. Four newly identified contacts travelled on Santiago de Chile–Madrid (18 Jul) or Madrid–Bordeaux (19 Jul); all six contacts were asymptomatic and home-quarantining, with tests for the four new contacts pending. The patient and two household contacts tested PCR-negative; the patient was discharged from epidemiological follow-up and returned to France, while the household contacts remain isolated to complete 42 days. CCAES assesses risk as very low for healthcare workers and extremely low for Spain’s general population. No established MV Hondius link; its final baseline remains 13 cases (12 confirmed, 1 probable), 3 deaths, outbreak over.
Argentina Ministry of Health BEN No. 820 (SE30, published 10 Aug 2026): the national bulletin records 53 cumulative confirmed hantavirosis cases in 2026 through SE30, compared with a 2022–2025 median of 38. The cumulative count is up one from BEN No. 819’s 52. The year-to-date trend is classified as increasing (en aumento), while the latest four weeks are below expected (por debajo de lo esperado). No death count or new guidance was reported; figures are preliminary and revisable. Endemic Argentine surveillance, unrelated to the contained MV Hondius outbreak (final baseline 13 cases — 12 confirmed, 1 probable — and 3 deaths).
Cooperativa, citing ISP and O’Higgins Seremi (7 Aug 2026): ISP confirmed hantavirus in an 11-year-old girl in Rengo who died. A preliminary investigation identifies travel to Bolivia as the probable exposure; O’Higgins reports 7 confirmed cases and 3 deaths in 2026. No arithmetic change is made to Chile’s official national SE30 total of 48 confirmed cases through 1 Aug: whether this case is included is not yet known, and a later national bulletin is needed to reconcile the figures. Separate endemic/imported Chile surveillance, unrelated to the contained MV Hondius outbreak.
Chile Ministry of Health — Epidemiological Bulletin SE30 (Aug 2026): Chile reports 48 confirmed hantavirus cases in 2026 through epidemiological week 30 (ending 1 Aug 2026), incidence 0.24 per 100,000 — up two from the previous 46-case baseline. Figures are official surveillance and may be revised; no updated death count was verified, so none is inferred. Endemic Chile surveillance, unrelated to the contained MV Hondius outbreak (final baseline 13 cases — 12 confirmed, 1 probable — and 3 deaths).
French Official Journal (8 Aug 2026): Decree No. 2026-751 authorizes quarantine for contacts assessed to face a serious Andes-virus infection risk and isolation for confirmed infections associated with the imported case, for up to 42 days from the last at-risk contact; prefectural authorities may enforce measures when urgent or necessary. This is a legal public-health management measure, not evidence of onward transmission. France's Health Ministry continues to assess transmission risk as very low; contact tracing continues and no MV Hondius link is established.
France Ministry of Health (7 Aug 2026): the risk of onward transmission from the imported Andes virus case is judged very low, concentrated among the closest and most prolonged contacts. The Franco-Argentine tourist, isolated with family in Galicia, Spain, is no longer symptomatic; the potential infectious window is assessed as 18–28 July and the diagnostic viral load was very low. Contact tracing continues. The case remains imported with no established link to the contained MV Hondius outbreak; risk is described as very limited rather than absent, and that outbreak's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Doherty Institute / Cumming Global Centre (6 Aug 2026): the Centre funded two early-stage Andes hantavirus therapeutic projects. University of Queensland researchers will develop bi-specific nanobody candidates intended to progress toward preclinical testing; Doherty Institute researchers will develop a CRISPR-Cas13 mRNA approach beginning in cell models and then animal models. Funded early-stage/preclinical research only: these are not approved or available treatments, not clinical evidence in people, and not an outbreak count or status change.
Argentina Ministry of Health BEN No. 819 (SE29, published 4 Aug 2026): the national bulletin records 52 cumulative confirmed hantavirosis cases in 2026 through SE29, compared with a 2022–2025 median of 37. The cumulative count is unchanged from BEN No. 818. The year-to-date level remains above expected, while the latest four weeks are within expected. Figures are preliminary and revisable. Endemic Argentine surveillance, unrelated to the contained MV Hondius outbreak; no change to its final 13 cases and 3 deaths.
Radio Santa María / Seremi de Salud Aysén (6 Aug 2026): Hospital Guillermo Grant Benavente's clinical laboratory confirmed two new hantavirus cases—the 62-year-old woman and her 17-year-old granddaughter transferred from Coyhaique. Aysén reports five confirmed cases in 2026, including one death earlier this year. Endemic Chile context, unrelated to the contained MV Hondius outbreak; no national Chile total is inferred, and the outbreak's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Tatarstan, Russia (31 Jul): two regional reports citing the deputy head of Tatarstan’s Rospotrebnadzor office say 324 hemorrhagic fever with renal syndrome (HFRS) cases were registered in January–July 2026, nearly double the same period in 2025 and up from 190 reported in late June. Officials said rodent infection and abundance exceed long-term averages and described the rise as part of a cyclical endemic increase. Regional surveillance context only: not a declared epidemic, unrelated to the contained MV Hondius outbreak, and no change to its final 13 cases and 3 deaths.
Radboudumc (31 Jul 2026): an internal review found that 12 staff — 7 nurses and 5 laboratory workers — may have been avoidably exposed to Andes virus through blood or urine while caring for an MV Hondius-linked patient; possible exposure does not mean infection, and no staff infection occurred. The review identified system factors rather than individual blame and recommends precautionary handling and HLIU admission for novel severe infections while protocols are developed. Institutional review only, not new WHO/RIVM guidance; all staff were out of quarantine by 22 Jun and the patient was discharged 20 May. No outbreak count or status change: WHO’s final baseline remains 13 cases (12 confirmed, 1 probable), 3 deaths, outbreak over.
Chile Ministry of Health (28 Jul 2026): Minsal declared Chile's first hantavirus Health Alert from Atacama through Magallanes, valid through 31 July 2027. Through the prior week, 2026 surveillance recorded 46 infections and 18 deaths (39% case-fatality proportion), versus 44 infections and 8 deaths (18%) in 2025. This is a preventive and preparedness measure for an endemic disease, not a declaration of an epidemic or overwhelmed health care. It is unrelated to the contained MV Hondius event; WHO's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
University of Queensland / Nature Communications (29 Jul): preclinical, host-targeted antiviral research reports that inhibiting the human enzyme NMT1 reduced viral infection in cell-culture (in vitro) tests of SARS-CoV-2, RSV and vesicular stomatitis virus — by about half after one day and up to about 90% after two days. Hantavirus itself was NOT tested; researchers only suggest the host-targeted mechanism could potentially apply to a range of viruses including hantavirus. Preclinical laboratory research only: not an approved hantavirus treatment, not clinical evidence in people, and not an outbreak count or status change; WHO's final MV Hondius baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Tres Arroyos Municipal Health Secretariat / LU24 (26 Jul): an official municipal communiqué says Tres Arroyos district has recorded two confirmed hantavirus cases in 2026, in February and July; Health Region I has three cases total, including one from another municipality. Epidemiological investigations linked both local cases to wild-rodent exposure, with no infections among close contacts and no evidence of person-to-person transmission in the district. Variant typing for the July case remains pending. These local figures may already be included in Argentina BEN No. 817's 51 confirmed cases through SE27 and must not be added to that national total. Unrelated to the contained MV Hondius outbreak; no change to its final 13 cases and 3 deaths.
RIVM (23 Jul 2026): more people than in previous years have fallen ill from Puumala orthohantavirus in Twente, the Netherlands, in 2026; this infection averages about 15 cases a year, and many affected people required temporary hospital admission. Reported exposures commonly involved nature, forests or meadows, or dust from mouse droppings while cleaning or sweeping sheds. A mast year and increased rodent abundance are one possible explanation. Puumala virus is different from Andes virus; this event is unrelated to the contained MV Hondius outbreak and does not change its final baseline of 13 cases (12 confirmed, 1 probable) and 3 deaths.
Canal Siete / regional epidemiology (23 Jul): a confirmed hantavirus patient, a rural worker in Tres Arroyos, Buenos Aires Province, remained in critical/guarded condition with slight improvement; strain testing was pending to determine whether this is Andes virus. The patient remained isolated under respiratory protocol; close family contacts were under daily symptom monitoring for the incubation window, with none symptomatic at report time, and environmental teams were investigating the rural workplace. This regional case is unrelated to the contained MV Hondius outbreak, with no change to its final 13 cases and 3 deaths. Argentina national cumulative placement awaits a later official bulletin; do not infer whether this case is already included in BEN No. 817's 51 confirmed 2026 cases through SE27.
BBC News Ukraine (23 Jul 2026): a Lviv regional laboratory confirmed hantavirus RNA by PCR in a 53-year-old Stryi resident with hemorrhagic fever with renal syndrome. Symptoms began 12 July and he was hospitalized 15 July. He had recently visited Croatia's Makarska Riviera and mountainous Ivano-Frankivsk region, but where and how infection occurred remain unknown; an epidemiological investigation continues. BBC cites Ukraine's Public Health Center as reporting 63 infections in the first three months of 2026 and 436 in 2025. Global context only, unrelated to the contained MV Hondius outbreak; its final count remains 13 cases and 3 deaths.
Argentina Ministry of Health BEN No. 817 (SE27, published 20 Jul 2026): SE27 bulletin records 51 confirmed hantavirosis cases in 2026 through SE27, versus a 2022–2025 median of 34; annual status is above expected, while the latest four weeks are below expected. SE26 also recorded 51, so there is no week-over-week increase; figures are provisional and revisable. Endemic Argentine surveillance, unrelated to the contained MV Hondius event (final: 13 cases, 3 deaths).
Reuters / AP (21 Jul): Venezuela's Health Ministry reported that three laboratory-confirmed hantavirus patients died in the rural Miranda municipality of Anzoátegui state; two additional deaths of health workers in Barinas are suspected, under investigation and unlinked. The ministry reports no evidence of person-to-person transmission in Venezuela and calls these isolated events that do not represent a general risk to the community. Regional news context only: explicitly unrelated to the contained MV Hondius outbreak and no change to its 13 cases (12 confirmed, 1 probable) and 3 deaths.
CIDRAP / JAMA Neurology review (20 Jul): a research review examines how hantavirus infection can, uncommonly, cause serious neurologic complications — including headache, delirium and seizures, and rarely more severe neurologic effects; long-term neurologic effects remain understudied and there is still no FDA-approved antiviral treatment or licensed vaccine. Research/clinical-context only: not a new outbreak case or count change; WHO's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
Argentina Ministry of Health / ANLIS Malbrán (16 Jul): Argentina's national reference laboratory says Malargüe, Mendoza rodents tested negative for hantavirus antibodies; Tierra del Fuego rodents carried a different hantavirus variant and were ruled out as the source linked to the MV Hondius event. ANLIS also sent Andes-virus diagnostic materials to laboratories in eight additional countries. Official source-investigation and laboratory-capacity update only: no new human case or MV Hondius count change; WHO's final baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.
ECDC (9 Jul): ECDC's Andes hantavirus surveillance page formally acknowledges that the 2026 MV Hondius Andes virus outbreak has been contained and declared over by the World Health Organization on 2 July 2026, and says the page is no longer being regularly updated; outbreak totals remain 13 cases (12 confirmed, 1 probable) and 3 deaths. Official post-outbreak closure acknowledgement that aligns with WHO DON611 (2 Jul) and supersedes ECDC's 17 June active-event surveillance; no count change.
CDC Emerging Infectious Diseases (9 Jul): A retrospective study of samples from 371 chronically ill patients collected from 2004–2018 in northwestern Italy found hantavirus IgG in 7.3%; PUUV-neutralizing antibodies were confirmed in 10 tested cases. The findings suggest previously unrecognized local circulation but cannot establish infection timing, symptom linkage, or current incidence. Research context only: unrelated to MV Hondius and no change to outbreak totals (13 total, 12 confirmed, 1 probable, 3 deaths).
Kommersant / Udmurtia Rospotrebnadzor (3 Jul): Udmurtia's regional Rospotrebnadzor reports 259 hemorrhagic fever with renal syndrome (HFRS) cases in January–June 2026, up from 80 in the same period of 2025; 166 were reported in June and incidence was 18.05 per 100,000. Reported exposures were household-related (49.5%), garden/dacha (26.1%), and forest activities (24.3%). The report attributes exposures to rodent-associated settings and does not report person-to-person transmission. Endemic regional Russia surveillance context (surfaced by ProMED 5 Aug), unrelated to the contained MV Hondius Andes-virus outbreak and not a change to its final 13 cases (12 confirmed, 1 probable) and 3 deaths.
WHO DON611 (2 Jul): WHO says the MV Hondius Andes hantavirus outbreak no longer poses a public-health risk and no further related transmission is expected after all identified contacts completed the 42-day follow-up period without additional secondary cases. As of 2 Jul, WHO reports 13 linked cases including 3 deaths: 12 laboratory-confirmed and 1 probable; 8 of 10 hospitalized cases have recovered and been discharged, and 2 remain in treatment. WHO also reports 317 high-risk contacts completed quarantine/monitoring and 336 low-risk contacts completed self-monitoring. Official outbreak-containment/status update; it updates closure/status while keeping the case baseline at 13 cases, 12 confirmed, 1 probable, and 3 deaths.
ProMED Mail (1 Jul): HANTAVIRUS - ARGENTINA (27): Santa Fe authorities confirmed the first hantavirus case this year in a rural area of Santa Fe Province, initiated containment protocols and an environmental investigation, and reminded the public to use hygiene measures that reduce rodent contact. News-context only: this is not an MV Hondius count source and does not change the ECDC/RIVM baseline of 13 cases (12 confirmed, 1 probable) and 3 deaths.
ProMED Mail (29 Jun): HANTAVIRUS - ARGENTINA (26): a woman in San Carlos de Bariloche, Río Negro, died from hantavirus; the report notes possible human-to-human transmission for the regional strain, alongside usual rodent-associated transmission, and advises prompt medical care if symptoms appear after outdoor activity or contact with a confirmed case. News-context only: not an MV Hondius count source or outbreak-total change.
Buenos Aires Times / AFP (29 Jun): Argentina's Health Ministry and ANLIS-Malbrán report hantavirus detection in five Abrothrix rodents captured in Tierra del Fuego, but the viral variant differs from the human MV Hondius outbreak variant and the analysed rodents were ruled out as the infection source linked to that event. Source-investigation context only: no new human case or MV Hondius count change; the source of the first patient's infection remains under investigation and the ECDC/RIVM baseline remains 13 cases (12 confirmed, 1 probable) and 3 deaths.

GMA News / Philippines DMW (20 Jun): Department of Migrant Workers Secretary Hans Leo Cacdac announced that 38 Filipino MV Hondius crew members returned to the Philippines after completing quarantine in the Netherlands; they had previously tested negative before quarantine, and this repatriation/monitoring-completion update does not change the official ECDC/RIVM outbreak baseline of 13 cases (12 confirmed, 1 probable) and 3 deaths.
WHO/Tedros (19 Jun): with no new MV Hondius-linked hantavirus cases reported in over three weeks and no new deaths since 2 May, WHO says the situation remains stable. AFP/MedicalXpress reports almost all passengers and crew quarantined in the Netherlands are now allowed to return home; context only, no formal all-clear/end declaration and no change to the 13-case baseline (12 confirmed, 1 probable, 3 deaths).
Eurosurveillance (18 Jun): peer-reviewed outbreak investigation summarises the MV Hondius-linked Andes orthohantavirus event at 13 cases as of 18 Jun (12 confirmed, 1 probable; CFR 23%), involving passengers (10/121; 8%) and crew (3/61; 5%) across 23 nationalities with medical evacuation, repatriation and coordinated contact tracing/quarantine follow-up. High-signal investigation context only; it does not change the ECDC/RIVM count baseline.
ECDC (17 Jun): official update last updated 17 June 2026 at 13:55 reports 13 cases in total (12 confirmed and 1 probable) in the MV Hondius-linked Andes hantavirus outbreak; some identified contacts have completed quarantine and others are expected to do so in the coming days, while public-health authorities continue monitoring contacts. This supersedes the older 11/12 Jun ECDC baseline for current official count/status but does not change case or death totals.
RIVM official update (18 Jun): almost all Netherlands-quarantined MV Hondius passengers and crew ended their 42-day quarantine on 18 June after release testing for Andes virus; all release tests were negative. One close contact of a later-hospitalised Andes-virus patient remains in quarantine longer. RIVM reports the outbreak total as 13 people ill and 3 deaths; no new case-count change.
CNN (16 Jun): RFK Jr. ordered an exposed MV Hondius passenger to remain in federal quarantine in Nebraska despite CDC/federal health-expert clearance to return home to Florida, CNN reports. This is a U.S. quarantine-policy/monitoring update for an exposed passenger, not a new infection, symptom report, or official case-count change.
Demócrata/EFE (16 Jun): Spain says the last patient remaining hospitalized at Central Defense Hospital Gómez Ulla due to MV Hondius-linked hantavirus infection was discharged Tuesday and is now at home; no MV Hondius outbreak patients remain admitted there. Clinical-outcome/status context for existing Spain cases only; no new infection and no official WHO/ECDC/CDC case-count change.
Health Policy Watch (16 Jun): after a WHO EPI-WIN briefing, Dutch, Spanish and Swiss clinicians reported using slightly different discharge criteria for MV Hondius-linked Andes hantavirus patients, and none required a negative blood PCR because blood can remain positive for months. Netherlands used two negative saliva tests; Spain required two negative throat/oropharyngeal and urine PCRs; U.S. home monitoring depends on isolation circumstances and PPE precautions. IPC/quarantine implementation context only; no WHO/ECDC/CDC case-count change.
WHO EPI-WIN (16 Jun): WHO is hosting an official IPC/guidance-event webinar on hantavirus/Andes virus infection prevention and control, focused on isolation, safe discharge, discontinuing transmission-based precautions, and quarantine implementation. WHO notes operational gaps remain around discharge criteria, de-escalation and quarantine settings; it says the MV Hondius outbreak involved human-to-human transmission but exact modes remain under investigation, and that ANDV does not behave like highly transmissible airborne diseases such as measles. Context only: no case-count change.
WHO (12 Jun): WHO says 21 countries launched NAVIS, a coordinated Andes-virus natural-history research initiative after the MV Hondius outbreak, to study transmission dynamics, incubation periods, immune responses, viral kinetics and severe-disease determinants using harmonized ISARIC-style data/sample collection. Research-preparedness context only: no approved vaccine/treatment and no WHO/ECDC/CDC case-count change.
NBC News (11 Jun): CDC and Florida health officials are at odds over MV Hondius passenger home-quarantine surveillance; NBC reports Florida is not planning CDC-requested round-the-clock surveillance for an exposed passenger seeking to leave the Nebraska National Quarantine Unit and complete quarantine at home. U.S. quarantine-implementation/policy dispute: 18 Americans were repatriated; as of the report 10 had left Nebraska for home-state surveillance and 8 remained at NQU; all Americans aboard tested negative/no symptoms; 42-day period scheduled to end 22 Jun. No change to the ECDC count baseline (13 cases, 12 confirmed, 1 probable, 3 deaths as of 11 Jun).
AP/ABC (11 Jun): State Department committed $750,000 to charter a yacht to evacuate one asymptomatic American citizen who had been aboard MV Hondius from remote Pitcairn Island toward Easter Island/Chile after French Polynesia declined admission; logistics/consular response for a potentially exposed but asymptomatic person, no official case-count change.
ECDC CDTR Week 24 (12 Jun): for the South Atlantic cruise-ship Andes virus outbreak, ECDC reports that as of 11 Jun there are still 13 cases (12 confirmed, 1 probable) and 3 deaths, with no new deaths since the previous update; one previously probable Tristan de Cunha-exposed case was laboratory-confirmed on 10 Jun (UKHSA/WHO). Sequencing from some positive cases showed high genetic similarity, likely indicating an initial zoonotic spillover followed by human-to-human transmission. This CDTR source does not change case/death totals; EU/EEA general-population risk remains very low and the likelihood of ANDV affecting the SoHO donor population is assessed negligible.
News-Medical/UTMB (11 Jun): UTMB reports a Lancet study (DOI 10.1016/S0140-6736(26)01124-4) of a single-dose mRNA Andes hantavirus vaccine candidate showed 100% protection in an animal challenge model and protective antibodies by 14 days; UTMB says NIH-supported work is being fast-tracked toward human trials. Research context only: preclinical/animal-model data, no approved hantavirus vaccine or specific treatment yet, and no WHO/ECDC/CDC outbreak-count change.
Federal Register (10 Jun): CDC proposes new “2026 Andes Hantavirus Cruise Passenger and Traveler Contact Monitoring” project under Docket CDC-2026-1024; 60-day public comment to 10 Aug 2026 (OMB 0920-0218, DGMH/NCEZID). No change to WHO/ECDC outbreak count (13/3).
Reuters (9 Jun): three additional U.S. MV Hondius hantavirus-exposed passengers left the Nebraska National Quarantine Unit on 9 June after four weeks of monitoring; eight of the original 18 have now returned home (five the week of 2 June, three on 9 Jun) and ten remain in Omaha, all continuing self-monitoring under local/state health departments for the rest of the 42-day incubation period; no change to the 13-case / 3-death WHO/ECDC outbreak count.
CBC (8 Jun): B.C. provincial health officer says the Canadian who tested positive for hantavirus after evacuating MV Hondius (a Yukon traveller in their 70s) has recovered and was discharged from hospital late last week; three other contacts remain asymptomatic under 42-day quarantine; clinical-outcome update for an existing confirmed case, no WHO/ECDC count change.

NL Times (12 Jun): MV Hondius is set to resume cruises from Longyearbyen/Spitsbergen this weekend after cleaning/disinfection and clearance; 137 passengers and an onboard doctor are expected for the new voyage. Operational/public-health response context only; no case-count change.
Taiwan CDC (7 Jun): New Zealand MV Hondius passenger completed 42-day/enhanced monitoring through 6 Jun; four Andes hantavirus PCR and IgM/IgG rounds were all negative, no symptoms reported, WHO and New Zealand notified via Taiwan IHR focal point; no count change.
Texas DSHS (6 Jun): two Texas residents monitored after MV Hondius exposure completed the 42-day monitoring period with no sign of infection and are no longer under public-health recommendations for that exposure; monitoring/status context, no case-count change.
Buenos Aires Times/AFP (12 Jun): Argentina Health Ministry says the Mendoza source investigation (ANLIS-Malbrán + CDC experts, >250 traps around Malargüe) did not find Oligoryzomys longicaudatus, the main known Andes virus reservoir in much of Patagonia; another rodent species may have been captured and further tests are underway. Source-investigation context only: no change to official outbreak counts.
Xinhua/China.org (5 Jun): Spain says the first Spanish MV Hondius patient, a 70-year-old man, was discharged after three symptom-free days and two negative PCR tests; follow-up continues, second Spanish positive had mild symptoms, 12 other Spanish passengers remain negative/quarantined; no count change.
Australian CDC / CDI Situation Report 5 (4 Jun): confirms WHO's 13-case, 3-death outbreak count (CFR 23%); ANDV added to Australia's Biosecurity Listed Human Diseases (12 May) and made nationally notifiable for 6 months (22 May); six repatriated Australian passengers still in quarantine; no case-count change.
AP (4 Jun): researchers in Chile, Argentina and the U.S. are pursuing hantavirus drugs and vaccines; no approved treatments or vaccines exist for the cruise-ship Andes-virus response, so this is research context, not new clinical guidance.
The Straits Times (7 Jun): Singapore CDA says two Singapore MV Hondius residents completed 42-day quarantine and were released 6 Jun after testing negative for hantavirus including Andes virus; last exposure was an Apr 25 flight shared with a confirmed case; public risk low; monitoring/status context, no official case-count change.
CDC FAQ (9 Jun): CDC says the MV Hondius Andes-virus outbreak is not like COVID-19; Andes virus does not spread easily person-to-person and usually requires close/prolonged contact with a symptomatic person or body fluids. Symptoms can appear 4–42 days after exposure; testing is for symptomatic people with known exposure; there is no specific treatment beyond supportive care. CDC says pandemic risk and U.S. public/traveler risk remain extremely low; no WHO/ECDC count change.
