MV Hondius hantavirus outbreak
2026 disease outbreak
In April 2026, an outbreak of hantavirus infection caused by the Andes virus was identified on the Dutch cruise ship MV Hondius. There were ten confirmed cases and two suspected cases directly linked to the outbreak as of 22 May. There have been three deaths, two of which have been confirmed as caused by the Andes virus, the last on 2 May. By 11 May, all passengers had disembarked and been evacuated, many to their home countries for quarantine. On 2 July 2026, the World Health Organization officially declared the outbreak to be over, after the last close contact was released from quarantine.
The Andes virus is the only known hantavirus to spread between humans. It spreads through close, sustained contact between people, and it may be airborne. The World Health Organization has emphasized that the risk of an epidemic is low, as previous outbreaks have only involved transmission in close-contact settings.
The ship departed from Ushuaia, Argentina, on 1 April with plans to visit Antarctica and several islands in the South Atlantic. A passenger died on board on 11 April.

Why this record matters
“MV Hondius hantavirus outbreak” is worth following because a concise public description often conceals a longer documentary argument. Here, Hondius, hantavirus and outbreak provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q139676879. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2026.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
