 Wuhan, capital of Central China's Hubei Province, reported seven local COVID-19 cases on Monday. The city has reported zero local infections since June 2020.   

Investigation shows Tang, an immigrant worker, had contacted with a tourist group from Huaian, a city in East China's Jiangsu Province grappling with the latest COVID-19 flare-up while waiting for a train at the Jiangzhou High-speed Railway Station in Wuhan on Friday.

Tang was identified during a screening campaign launched by the Wuhan economic development zone targeting travelers from key regions on Sunday night, according to a statement released by the zone's management office. 

Tang and another six close contacts tested positive following nucleic acid testing on Monday. They were sent to a designated hospital for further diagnosis and treatment. All places they had been to have been disinfected.

All people related to the infections have been under close-off management and were demanded to take nucleic acid tests. Epidemiological survey is underway. 

Previously, Huai'an authorities noticed that a local company had organized a train journey from Jingzhou to Hefei in East China's Anhui Province for 67 employees to Zhangjiajie, Central China's Hunan Province. On Sunday, 10 people from the group including the tour guide tested positive for COVID-19. Two close contacts, who are spouses of some members of the group, also tested positive.
