U.S. officials learned cruise ship evacuees were infected at the last minute.

A day before 328 Americans were to be whisked away from a contaminated cruise ship in Japan, the U.S. Embassy in Tokyo told passengers that no one infected with the new coronavirus would be allowed to board charter flights to the United States.

But those plans were hastily changed after the test results for 14 passengers came back positive — just as they were being loaded onto buses and dispatched to the airport, where two reconfigured cargo jets were waiting to fly them to military bases in California and Texas.

After consultations with health experts, the U.S. government decided to let the infected evacuees, who were not yet exhibiting symptoms, board the flights.
