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.
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. Australia/New Zealand monitoring-completion context only; no infection or official count change, with the ECDC/RIVM baseline remaining 13 cases (12 confirmed, 1 probable) and 3 deaths.
CDC situation summary (22 Jun): on June 21, all U.S. citizens potentially exposed to hantavirus aboard the M/V Hondius finished their 42-day monitoring period.

Official U.S. monitoring-completion/status update only; no change to the ECDC/RIVM baseline of 13 total cases, 12 confirmed, 1 probable, and 3 deaths.
UKHSA / GOV.UK (22 Jun): UKHSA confirms all remaining individuals have now left Arrowe Park, and all passengers from MV Hondius who subsequently returned to the UK have now completed their self-isolation periods. UK monitoring/self-isolation completion context only: no new infection, no official ECDC/RIVM/WHO/CDC count change; baseline remains 13 cases, 12 confirmed, 1 probable, 3 deaths; CDC's 22 Jun situation summary says no U.S. hantavirus disease cases occurred as a result of this outbreak.

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.

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.

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).

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.

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.

CDC says pandemic risk and U.S. public/traveler risk remain extremely low; no WHO/ECDC count change.

2026 Hantavirus Cruise Outbreak Tracker
Hantavirus Lookout tracks public reports tied to the 2026 Andes virus cluster linked to the MV Hondius cruise itinerary, including confirmed cases, reported deaths, people still under suspected/testing status, and monitored contacts. The dashboard is designed to make the current tracked counts and involved locations easier to scan while keeping source-quality notes on the Sources & Methodology page.
Involved Locations And Spread
The map and feed emphasize locations named in public reporting, including South America exposure points, the cruise vessel route, repatriation or quarantine locations, and countries monitoring exposed travelers. Andes virus is notable because, unlike most hantaviruses, it has documented person-to-person spread during close contact.
Confirmed vs Suspected vs Monitored
Confirmed cases are reported positive infections. Suspected/testing records are people with symptoms or pending evaluation. Monitored contacts are people being followed because of exposure, and they should not be counted as confirmed infections unless a source later reports a positive result.
