Hantavirus outbreak: They were on the trip of a lifetime. Now they’re quarantined as health officials work to contain the virus

Key Points:

• Most American passengers from the MV Hondius cruise ship, which experienced a hantavirus outbreak, are now quarantined at the National Quarantine Unit in Omaha, Nebraska, facing potential weeks of isolation as part of a global repatriation effort.
• Since the outbreak was reported by the WHO, 122 people have been evacuated from the ship, with the remaining crew and medical staff sailing to Rotterdam for disinfection; three passengers have died, and several cases have been confirmed or are probable.
• The Andes variant of hantavirus is believed to have transmitted human-to-human on the ship, prompting close monitoring of affected individuals in the US and other countries, with some patients in biocontainment units and others asymptomatic in quarantine.
• The ship made multiple stops during its expedition, leading to potential exposure in various regions; cases have been confirmed in France and Spain, and authorities worldwide are continuing testing and containment measures.
• Despite the outbreak, health officials emphasize that the risk to the general public remains very low due to the virus’s limited transmission mode, requiring prolonged close contact with symptomatic individuals.
