as the authorities demanded high vigilance at ports of entry amid growing infections in a northeastern border city caused by the virus arriving from abroad.
Some 377 domestically transmitted cases with confirmed symptoms were reported from Oct. 17-29, National Health Commission (NHC) data showed. China has tackled a series of outbreaks this year since it largely contained a national spread in early 2020.
The numbers remain tiny compared with clusters outside the country. However, while the rest of the world works out how to co-exist with COVID, China has maintained its zero tolerance, urging vigilance around border areas and ports to prevent infected inbound travellers spreading the virus to locals.
"Within the past 14 days, 14 provincial areas have reported new locally transmitted cases or asymptomatic carriers," the NHC spokesperson Mi Feng said on Saturday.
"The outbreak is still developing rapidly, and the virus control situation is severe and complicated."
