The World Health Organization has confirmed two cases of hantavirus on a cruise ship currently moored off the coast of West Africa, where three people have died. One adult woman has died and one adult man is hospitalized in a South African intensive care unit after lab tests confirmed hantavirus infection. The other two deceased individuals are suspected to have been infected with the same virus.
The WHO reported Monday that three additional suspected cases among the 147 people still on board—88 passengers and 59 crew members—have shown mild symptoms. The ship has been docked off Cape Verde, an archipelago nation off West Africa, and passengers have been instructed to stay in their cabins and practice physical distancing.
Global Risk Assessment
WHO Director-General Tedros Adhanom Ghebreyesus described the estimated global risk from this outbreak as “low” on Tuesday, adding that the agency will continue monitoring and updating the situation. “WHO is working with the countries involved and the ship’s operator to support the passengers and crew,” Ghebreyesus said in a social media post. He outlined a coordinated international response including in-depth investigations, case isolation, medical evacuation, and lab work.
The outbreak has drawn a multinational response involving the Netherlands, Spain, South Africa, and the United Kingdom, all working with the WHO to contain the virus. The ship began its journey on April 1 from Ushuaia, Argentina, with stops in Antarctica and several South Atlantic islands before reaching its current location.
Virus Characteristics and Symptoms
According to the WHO, illness onset among affected individuals occurred between April 6 and 28, with symptoms including fevers, gastrointestinal issues, pneumonia, acute respiratory distress, and shock. Hantavirus is primarily contracted through contact with infected rodents and is a rare but severe disease that can be deadly. While human-to-human transmission is uncommon, the WHO noted that limited spread has occurred in previous outbreaks of the Andes virus, a specific hantavirus species.
In the United States, the CDC reported 890 hantavirus cases in 2023, with a 35 percent fatality rate. Europe saw 1,885 infections that same year. There is no vaccine or specific treatment for hantavirus, but early medical intervention can improve survival chances, the WHO emphasized.
Broader Context
This incident underscores the challenges of managing rare diseases in confined environments like cruise ships, where isolation and rapid response are critical. The WHO’s coordinated effort mirrors responses to other global health threats, though the low risk assessment suggests limited immediate impact beyond the ship.

The outbreak also highlights the role of international cooperation in public health emergencies, a dynamic that has seen increased attention amid ongoing geopolitical tensions. Meanwhile, the Trump administration’s approach to health and security issues continues to evolve, as seen in the extension of the Israel-Lebanon ceasefire.
As the situation develops, health authorities are focused on preventing further spread and ensuring the safety of those on board. The WHO’s monitoring will continue, with updates expected as investigations proceed.
