A number of COVID-19 cases have been detected through on-site nucleic acid testing when travelers arrive at airports, train stations and highway exits, a method recently adopted across China to address the escalated risk brought about by increasing population flow as the National Day holidays approach.
On-site testing is adopted to ensure no emergence of sizable domestic outbreaks before and after the National Day holidays, the National Health Commission (NHC) said on September 8 at a press conference. It is a key method to detect cross-region imported cases, the NHC noted.
Testing labs have been set up at each train station, airport and highway exit in multiple cities including Shanghai and other places in Northeast China's Jilin Province.
East China's Jiangsu Province adopted the same measures recently. As the National Day holidays approach, more people from provinces out of Jiangsu have called to ask about epidemic-related policies, according to the worker. On Thursday, Jiangsu's Xuzhou city found one case through on-site testing at a train station.
