Outbreak Details
The MV Hondius, a Dutch-flagged cruise ship, reported a cluster of severe respiratory illnesses among its passengers and crew. As of May 4, 2026, seven cases have been identified, including three deaths. The World Health Organization (WHO) confirmed that the virus involved is the Andes hantavirus, known for its potential human-to-human transmission.

Transmission and Impact
Hantavirus is typically transmitted through contact with infected rodent excretions. However, the Andes strain can spread between humans, particularly among close contacts. The confined environment of the cruise ship may have facilitated this rare transmission route.
