WHO Declares Hantavirus Outbreak Linked to Cruise Ship Over

The World Health Organization declared the hantavirus outbreak linked to the cruise ship MV Hondius over on Thursday, February 17, 2026. The declaration came after the last identified contact of an exposed person completed quarantine and tested negative for the virus. This outbreak involved the Andes virus, a rare hantavirus strain typically found in Argentina and Chile. The MV Hondius set sail from Argentina on April 1.

The outbreak infected a total of 13 people and resulted in three fatalities. The WHO's decision marks the end of the public health concern associated with this specific transmission event. Hantaviruses are a group of viruses spread mainly by rodents, and while rare, can cause severe illness in humans. The Andes virus is known for its potential to spread from person to person, a characteristic that made this cruise ship outbreak particularly concerning.

Public health officials monitored the situation closely following the ship's return and identified individuals who had potential contact with infected persons. The implementation of quarantine measures and subsequent testing were crucial steps in containing the spread and ultimately declaring the outbreak resolved. The WHO's timely intervention and guidance played a significant role in managing the situation and ensuring the safety of the public.
