CDC Monitoring 41 People in US for Andes Hantavirus Following Cruise Ship Outbreak

The CDC is monitoring 41 individuals in the United States for potential Andes hantavirus exposure following a rare outbreak on the MV Hondius cruise ship. The World Health Organization has confirmed 11 cases among passengers, including three deaths. Eighteen cruise passengers are currently quarantined in facilities in Nebraska and Georgia, while additional monitoring includes those who returned home before the outbreak was identified and passengers exposed during air travel with symptomatic individuals. The 42-day monitoring period reflects the incubation time for hantavirus symptoms. CDC officials emphasize that most monitored individuals are considered high-risk exposures and should remain at home, avoiding contact with others and refraining from travel. The Andes virus, a South American hantavirus strain capable of person-to-person transmission, carries approximately a 35% fatality rate. Symptoms progress rapidly from flu-like illness to severe respiratory distress.
