Hantavirus Detected on Cruise Ship in Rare Human Spread

The World Health Organization (WHO) has warned that hantavirus may have spread between passengers on a cruise ship. Two cases of the virus were confirmed on board, and three people have died. Health officials around the world are now monitoring the situation carefully.

Hantavirus is a serious disease that people usually catch from infected rodents, such as mice or rats. It very rarely passes from one person to another, which makes this case highly unusual. Scientists are still studying how the passengers became infected during their voyage.

The WHO released its official statement on May 5, 2026, calling on health authorities to investigate the outbreak right away. Officials have not yet revealed the name of the ship or its travel route. However, they confirmed that two passengers tested positive for the virus, and a third possible case is under review.

Cruise ship companies have been told to strengthen their health checks and report any suspicious symptoms immediately. Passengers from the same ship are being asked to monitor their health for several weeks. Medical teams are contacting those who may have been near the infected travelers.

Experts say this event shows how quickly diseases can spread in closed spaces like ships. People planning cruises should follow health guidance and report signs of illness early. The WHO promises to share more information as the investigation continues.
