Quarantine restrictions end for 18 American passengers who were exposed to hantavirus while onboard the MV Hondius, according to the U.S. Centers for Disease Control and Prevention (CDC) and reported by multiple outlets. The Americans complete their 42-day monitoring period after being exposed more than a month earlier, and CDC guidance indicates no related hantavirus cases have been confirmed in the United States.

The outbreak linked to the MV Hondius involved confirmed cases and one probable case, with reporting across sources citing 12 confirmed infections and one probable case. Three deaths are also reported as part of the outbreak. The cluster prompted an international health alert.

While the accounts focus on the end of quarantine for the Americans, sources align on the core public-health details: the ship’s outbreak included both confirmed and probable cases, and the U.S. quarantine measures for the exposed Americans conclude after the monitoring period, with officials reporting no U.S.-confirmed cases associated with the incident.
