BEIJING (AP) — Chinese health authorities urged people in the city of Wuhan to avoid crowds and public gatherings, after warning that a new viral illness that has infected more than 400 people and killed at least nine could spread further.
The appeal came before a World Health Organization meeting in Geneva later Wednesday to determine whether the outbreak should be declared a global health crisis.
The United States on Tuesday reported its first case of the virus, saying a Washington state resident who returned last week from the outbreak's epicenter was hospitalized near Seattle.
The man, identified as a Snohomish County resident is in his 30s, was in good condition and was not considered a threat to medical staff or the public, health officials said.
U.S. officials said they believe the virus’ overall risk to the American public remained low.
"This is not a moment of high anxiety," Gov. Jay Inslee said.
The number of new cases has risen sharply in China, the center of the outbreak. There were 440 confirmed cases as of midnight Tuesday in 13 jurisdictions, said Li Bin, deputy director of the National Health Commission. Nine people have died, all in Hubei province, since the outbreak emerged in its provincial capital of Wuhan late in December.
"There has already been human-to-human transmission and infection of medical workers," Li said at a news conference with health experts. "Evidence has shown that the disease has been transmitted through the respiratory tract and there is the possibility of viral mutation."
The illness comes from a newly identified type of coronavirus, a family of viruses that can cause the common cold as well as more serious illnesses such as the SARS outbreak that spread from China to more than a dozen countries in 2002-2003 and killed about 800 people.
Authorities in Thailand on Wednesday confirmed four cases, a Thai national and three Chinese visitors. Japan, South Korea, the United States and Taiwan have all reported one case each. All of the illnesses were of people from Wuhan or who recently traveled there.
"The situation is under control here," Thai Public Health Minister Anutin Charnvirakul told reporters, saying there are no reports of the infection spreading to others. "We checked all of them: taxi drivers, people who wheeled the wheelchairs for the patients, doctors and nurses who worked around them."
Macao, a former Portuguese colony that is a semiautonomous Chinese city, reported one case Wednesday.
President Donald Trump said: "We do have a plan, and we think it's going to be handled very well. We've already handled it very well. ... We're in very good shape, and I think China's in very good shape also."
In Wuhan, pharmacies limited sales of face masks to one package per customer as people lined up to buy them. Residents said they were not overly concerned so long as they took preventive measures.
"As an adult, I am not too worried about the disease," Yang Bin, the father of a 7-year-old, said after buying a mask. "I think we are more worried about our kids. ... It would be unacceptable to the parents if they got sick."
Medical workers in protective suits carried supplies and stretchers into Wuhan Medical Treatment Center, where some of the patients are being treated.
