MV Hondius — en route to Rotterdam (approx. position)
MV Hondius en route from Tenerife to Rotterdam. Left Tenerife ~12 May after last passengers disembarked. Expected Rotterdam 17 May. 27 crew remain onboard under health monitoring. Position is a calculated estimate based on typical vessel speed — not live AIS data.
Monitoring cluster — British nationals quarantined (Arrowe Park Hospital, Wirral)
~20 British nationals from MV Hondius quarantined at Arrowe Park Hospital, Wirral. Under 42-day observation protocol. UK Public Health England recommending all returning passengers self-isolate.
MV Hondius departs from Ushuaia, Argentina — the primary gateway for Antarctic expeditions and a region endemic for Andes virus. 173 passengers and crew onboard during this voyage.
Patagonia is the established endemic region for Andes virus (ANDV) — the only hantavirus with documented person-to-person transmission. The long-tailed pygmy rice rat is the primary reservoir host in this region.
Hantavirus Outbreak 2026 — Live Map & Case Tracker
Live hantavirus outbreak map and case tracker for the 2026 MV Hondius cruise ship cluster. 9 confirmed cases, 3 deaths as of May 13, 2026 (WHO). Cases in 12+ countries including USA, UK, Netherlands, Germany, Switzerland, and France. Updated hourly from WHO, ECDC, CDC, ProMED and 20+ sources.
Hantavirus 2026 Outbreak: Current Situation
In April–May 2026, an Andes virus (ANDV/hantavirus) outbreak was confirmed among passengers and crew of the MV Hondius, an expedition cruise vessel operated by Oceanwide Expeditions. The ship departed Ushuaia, Argentina on 1 April 2026 and operated in Patagonia and the Antarctic Peninsula with 147 passengers and crew from 23 countries.
As of 13 May 2026, WHO has confirmed 9 cases of Andes virus and 3 deaths. Three deaths occurred during the voyage: a Dutch man died on 11 April at sea, a Dutch woman died on 26 April in Johannesburg, South Africa, and a German woman died on 2 May at sea. The MV Hondius departed Tenerife on 12 May and is en route to Rotterdam, expected approximately 17 May 2026.
Confirmed or suspected cases have been identified in: Netherlands, United Kingdom, United States, Germany, Switzerland, France, Spain, Canada, South Africa, Singapore, Greece, and Tristan da Cunha. This map tracks all public data from official authorities and trusted media sources.
What is Andes virus (ANDV)?
Andes virus (ANDV) is a hantavirus found primarily in Argentina and Chile. It is the only hantavirus known to be capable of person-to-person transmission, in addition to the more common rodent-to-human transmission route.
Andes virus causes Hantavirus Pulmonary Syndrome (HPS), a serious respiratory illness. The reservoir host is the long-tailed pygmy rice rat (Oligoryzomys longicaudatus), found throughout Patagonia.
Patagonia, including southern Argentina and Chile, is the established endemic region for Andes virus. The Antarctic Peninsula region is reached via Patagonian ports such as Ushuaia.

How data is verified
Sources are monitored automatically every 30–60 minutes. When a source page changes, the update is queued for review. No data is published automatically — each item requires a human review step before it appears on the public map.
Every public datum includes: the source name, a confidence label, a last-checked timestamp, and a link to the original source where available.
Statistics such as confirmed case counts and risk levels are not published until they appear in official public health authority communications.
