U.S. Cruise Passengers Begin 42-Day Quarantine Following Hantavirus Exposure on MV Hondius

Following a hantavirus outbreak aboard the MV Hondius cruise ship that sickened at least 11 passengers and caused 3 deaths, more than a dozen exposed American passengers returned to the U.S. and entered mandatory quarantine at the University of Nebraska Medical Center on May 11, 2026. Asymptomatic but potentially exposed individuals will undergo 42-day observation with daily health monitoring. Some may transition to home quarantine in Texas, California, Washington, and Virginia under CDC guidance requiring isolation precautions including masking, distancing, and avoiding shared items. Health officials stress that hantavirus spreads primarily through prolonged contact with symptomatic patients. Those quarantining at home are cooperating voluntarily, though authorities retain the option to issue legal quarantine orders if compliance lapses. Proximity to specialized medical care—capable of providing heart-lung bypass for critical pulmonary cases—remains a key consideration in placement decisions.
