Coronavirus Live Updates: U.S. Evacuates Citizens From Hot Zone, and Death Toll Mounts

Virus shows signs of spreading overseas with people who never visited China falling ill in Germany, Japan, Taiwan and Vietnam.

Chinese officials confirmed nearly 6,000 cases of the mysterious illness as foreign governments airlifted their citizens out of Wuhan, the outbreak’s epicenter.

A chartered plane carrying more than 200 Americans from Wuhan, the epicenter of the coronavirus outbreak in China, landed in Anchorage shortly after 9:20 p.m. local time on Tuesday, according to flight tracking services.

The 240 passengers, including diplomats and businesspeople, were to undergo medical screening at Ted Stevens Anchorage International Airport, the local authorities said. The plane was also to be refueled before flying to March Air Reserve Base in Riverside County, Calif., its final destination.

Jim Szczesniak, the airport manager, said that the aircraft would be “handled in a remote location” and that medical staff from the United States Centers for Disease Control would check patients in an isolated area. Passengers would remain in a terminal that is not currently being used by commercial carriers or accessible to the public.

“The passengers will be screened and go through the immigration process,” Mr. Szczesniak said. “They will reboard their flight and head to their final destination.”
