China has tightened requirements for passengers flying in from the US amid a spike in imported COVID-19 cases among those traveling from the US.
Despite the inconvenience the stricter rules have created for those wishing to return to China, health experts and passengers said such measures are necessary as the worsening COVID-19 situation in the US and discovery of fake test reports are threatening China's epidemic control.
Amid a spike in imported cases from the US, the Chinese embassy in the US requires IgM serum antibody tests be performed through venous blood sampling only, and samples taken by finger prick are no longer acceptable starting Wednesday. Both antibody and nucleic acid tests must specify the testing methodology, the embassy posted on its website on Saturday.
To avoid infections during transit, passengers must be tested at laboratories on a list authorized by the embassy in the direct flight departure cities, which are Los Angeles, San Francisco, Seattle, New York, Detroit and Dallas.
Passengers are not allowed to board before obtaining a health code from the embassy by providing negative reports and other documents.
The US on Saturday local time reported a world new high of more than 400,000 daily infections, which is almost double of recent average, bringing total cases to 17.6 million. The death toll in the country topped 315,000 and another 200,000 may die by April, according to a simulation by the University of Washington.
