U.S. To Repatriate Americans From Quarantined Cruise Ship

A cruise ship in Japan faced a coronavirus outbreak, leading to a quarantine. The US Embassy announced an evacuation plan for US citizens aboard, using a chartered aircraft. Passengers over 80, with medical conditions, or in windowless rooms could disembark if they tested negative. The repatriation is voluntary, and returning passengers will be monitored for 14 days.
