Three people died on a cruise ship traveling from Argentina to Cape Verde after an outbreak of hantavirus [1].
The situation has raised alarms among health officials because the specific Andes strain of the virus can spread between humans through respiratory droplets [4]. This capability, combined with the close quarters of a cruise ship, has prompted the World Health Organization (WHO) to monitor the vessel as it approaches European coasts [2].
The WHO said the deaths occurred on May 3, 2026 [2]. Sequencing of the virus reported on May 5, 2026, confirmed the presence of the Andes strain [4]. While most hantavirus infections occur through contact with infected rodents, the Andes strain is distinct for its ability to transmit via saliva droplets [4].
Public health monitoring has expanded across Europe. One confirmed case of hantavirus has been reported in Switzerland [3]. Additionally, reports indicate that the Picardie region of France has also been affected by the virus [3].
Despite these cases, the WHO said the risk of a wider pandemic remains low [2]. The organization is working to address the unknowns surrounding this unusual sanitary event while providing reassurance to the public [2].
Health officials continue to track the movement of the ship and the health of its passengers to prevent further transmission upon arrival in Europe [2].

The emergence of the Andes strain in European waters is a significant public health concern because it breaks the traditional rodent-to-human transmission cycle. While the WHO maintains that the pandemic risk is low, the presence of confirmed cases in Switzerland and France suggests that monitoring and rapid diagnostic sequencing are critical to preventing a localized cluster from becoming a larger regional outbreak.
