The World Health Organization has reassured the public that a deadly hantavirus outbreak on a cruise ship in the Atlantic Ocean does not signify the beginning of a health crisis similar to the COVID-19 pandemic. During a press briefing on Thursday, Dr. Maria Van Kerkhove, WHO director for epidemic and pandemic preparedness and prevention, emphasized that the situation is contained and fundamentally different from previous global health emergencies.
Localized Outbreak Confirmed
“This is not the start of an epidemic. This is not the start of a pandemic,” Van Kerkhove stated firmly. “This is not Covid.” The outbreak involves the MV Hondius, a vessel carrying approximately 147 people. As of May 7, 2026, health authorities have identified eight cases, including five laboratory-confirmed infections and three suspected cases. Three fatalities have been recorded since the ship departed from Ushuaia, Argentina, in late March.
Andes Strain Identified
Scientists have identified the pathogen as the Andes strain of hantavirus. This strain is notable for its limited human-to-human transmission, which occurs only through close and prolonged contact. The WHO noted that while the confined environment of a cruise ship can facilitate this rare form of spread, the virus is not capable of the rapid airborne transmission seen with coronaviruses.
The current hypothesis suggests that passengers were exposed to the virus in Argentina before boarding. The MV Hondius is currently en route to the Canary Islands, where Spanish authorities will permit docking for a full epidemiological investigation and comprehensive disinfection procedures.
Risk to General Population Remains Low
“This is an outbreak that we see on a ship,” Van Kerkhove explained, stressing that the risk to the global population remains very low. She clarified that hantavirus does not spread like coronaviruses because it requires close, intimate contact. The WHO has released emergency funds to support the international response, including contact tracing for passengers who disembarked earlier during the voyage.
