In Japan, around 200 evacuees landed on Wednesday morning at Tokyo's Haneda Airport. Officials say several of them have symptoms such as coughing and fever. They say passengers received medical exams on board. All have been sent to medical institutions to undergo tests.
The four who are showing symptoms have been brought to a special medical institution for infectious diseases.
Two of the evacuees spoke to reporters at the airport.
Takeo Aoyama said, "I'm relieved that I was able to return to Japan on a chartered plane so quickly."
Japanese officials plan to charter additional flights from the virus-hit city. They say about 650 people in Wuhan have indicated they want to be repatriated to Japan.
Three more cases were confirmed in Japan on Tuesday, bringing the total to seven. One involves a Japanese bus driver in Nara Prefecture who had been working with Chinese tour groups.
Officials in Tokyo are taking special protective measures. People can now be hospitalized without their consent. Anyone suspected of carrying the virus at ports of entry will be told to undergo medical tests.
