World Health Organization officials said there is a hantavirus outbreak among passengers and crew aboard the cruise ship MV Hondius this week.
The situation represents a rare and lethal viral spread in a confined maritime environment, prompting international health alerts to prevent further transmission.
WHO Director-General Tedros Adhanom Ghebreyesus and other officials, including Dr. Maria Van Kerkhove, said the outbreak has resulted in three deaths: a Dutch couple and a German national [1].
Reports on the total number of infections vary. A WHO briefing cited five confirmed cases [2], while other health officials identified at least eight confirmed or suspected cases [3]. The ship is expected to dock in Tenerife, Spain, on Saturday, May 7, 2026 [6].
Health authorities are currently tracing roughly 40 passengers who have already disembarked from the vessel [4]. The rare nature of the infection has led 12 countries to place hantavirus on high alert [5].
Officials including Dr. Abdirahman Mahamud and Anais Legand said they are monitoring the situation as the ship approaches the Spanish coast. The WHO continues to coordinate with local authorities to manage the quarantine and medical response for those affected.
“The outbreak has resulted in three deaths: a Dutch couple and a German national.”
The emergence of hantavirus on a cruise ship is highly unusual, as the virus is typically contracted through contact with rodent droppings rather than person-to-person transmission. The scale of the alert—affecting 12 countries—suggests that health officials are prioritizing the prevention of a wider cluster of cases resulting from the movement of disembarked passengers across international borders.
