U.S. health officials announced on December 28 that starting from January 5, all passengers aged 2 or above from mainland China, Hong Kong and Macau will need to submit a negative virus test certificate within two days before departure before boarding a plane to the United States.
Reuters and the Associated Press reported that the United States is the second country after India, Japan, Italy, and South Korea to take countermeasures in response to the development of mainland China.
Washington officials said travelers who tested positive for the virus more than 10 days before departure could present proof of recovery in lieu of a negative virus test result.
After the Chinese government recently began to relax strict epidemic prevention measures that have lasted for many years, many international health experts are worried that the spread of the new coronavirus is difficult to control, and millions of people are expected to be infected every day.
Washington officials had earlier cited a lack of transparency in China's handling of the outbreak as the reason for considering travel restrictions on Chinese travelers.
