WHO said two cases were laboratory-confirmed in South Africa, three more suspected cases remain aboard, and the vessel carrying 147 people is moored off Cabo Verde.
The ship left Ushuaia on 1 April and visited Antarctica, South Georgia, Tristan da Cunha, Saint Helena and Ascension Island, with investigators still trying to identify the exposure source.
Cabo Verde, the Netherlands, South Africa, Spain and the UK are coordinating response measures, while WHO assesses the global risk as low and advises against travel or trade restrictions.

Deadly Hantavirus Outbreak Aboard MV Hondius Cruise Ship Sparks Global Health Crisis and Quarantine
Overview
In April 2026, the MV Hondius cruise departed Ushuaia, Argentina, with no initial hantavirus symptoms among passengers. Shortly after, several passengers developed symptoms, leading to a hantavirus outbreak onboard. Cape Verde authorities refused docking to prevent land transmission, enforcing strict isolation and hygiene measures by the cruise operator. The outbreak caused multiple deaths and critical illnesses, with medical evacuations coordinated internationally amid challenges due to limited onboard care. Investigations suggest exposure likely occurred in Ushuaia, involving the Andes virus known for rare human-to-human spread. The World Health Organization leads global coordination, while the incident highlights urgent needs for improved rodent control, surveillance, and crisis management in the cruise industry.
