What is hantavirus?

According to the CDC, the disease is transmitted to humans through “contact with rodents like rats and mice, especially when exposed to their urine, droppings, and saliva.”

On Saturday, a third passenger died. The body remains on board, according to a source cited by AFP.

Meanwhile, a second confirmed case of hantavirus involves a British man who was evacuated to South Africa on April 27. He is currently being treated in isolation in an intensive care unit and is reported to be in critical condition.

No one on board is allowed to leave the ship

In addition to the confirmed cases, more people are suspected of being infected. The World Health Organization (WHO) is now investigating whether the virus may have spread between people.

WHO confirmed in a statement: “As of 4 May 2026, seven cases (two laboratory confirmed cases of hantavirus and five suspected cases) have been identified, including three deaths, one critically ill patient and three individuals reporting mild symptoms.”

The cruise ship, carrying 149 people, is currently anchored off Praia, the capital of Cape Verde, after being denied entry to the port.
