WHO Reports Hantavirus Outbreak Kills Three on Cruise Ship Stranded Off Cape Verde

The World Health Organization reported seven hantavirus infections, including three deaths, aboard the Dutch-flagged MV Hondius cruise ship carrying 147 passengers and 59 crew of 23 nationalities. PCR testing confirmed the Andes virus strain, the only hantavirus with documented human-to-human transmission capability. The vessel, operated by Oceanwide Expeditions, departed Ushuaia, Argentina on April 1 and transited Antarctica, South Georgia, Tristan da Cunha, Saint Helena, and Ascension Island before anchoring off Praia, Cape Verde after being refused permission to dock. Illness onset occurred between April 6 and 28, with rapid progression to pneumonia, acute respiratory distress syndrome, and shock. WHO assessed global risk as low on May 4 and recommended against travel or trade restrictions.

Analysis
The Andes virus identification is the critical variable: the only hantavirus with documented human-to-human transmission capability, meaning the 147 passengers and crew represent potential secondary vectors across 23 countries. The three-week gap between first illness onset and laboratory confirmation (April 6–May 2) closed the contact-tracing window before containment began. Stops at Saint Helena and Tristan da Cunha, both lacking robust diagnostic capacity, add surveillance gaps that could delay case detection if transmission occurred ashore. Per the sole WHO outbreak bulletin, the low attack rate relative to confined-space exposure time may indicate rodent-sourced origin rather than person-to-person spread, which would substantially reduce secondary-case risk among disembarked passengers.
