The United States Centers for Disease Control and Prevention (CDC) on 8 May 2026 classified a hantavirus outbreak as a Level 3 emergency response following infections linked to the cruise ship MV Hondius. The CDC stated that the activation is primarily for enhanced monitoring, emergency coordination, and deployment of public health support teams.
Hantavirus is a rodent-borne disease that spreads mainly through exposure to infected rodent droppings, urine, or saliva. The outbreak involves the Andes strain of hantavirus, a rare variant known for limited human-to-human transmission in certain cases. Health authorities are closely tracking passengers and contacts associated with the voyage.
The outbreak originated aboard the Dutch-flagged cruise ship MV Hondius, operated by Oceanwide Expeditions. The vessel carried nearly 150 passengers from 23 countries, with the first confirmed case reported on 2 May 2026. According to the World Health Organization (WHO), five confirmed infections, three suspected cases, and three deaths had been reported by 8 May 2026.
International tracing efforts are underway for more than two dozen individuals from at least 12 countries who disembarked from the vessel on 24 April 2026. The ship is expected to dock in Spain’s Canary Islands for further medical assessment and containment measures.
The CDC clarified that a Level 3 response represents the agency’s lowest emergency activation level and is generally used when the risk to the wider public remains low but requires active surveillance and coordinated response measures. The WHO has also stated that the outbreak is not expected to develop into a global pandemic similar to COVID-19.
Hantavirus outbreaks remain relatively rare but are closely monitored because of their severe respiratory complications and high fatality rates in some cases.
