Some communities in Beijing kicked off mass nucleic acid testing for residents after four new confirmed COVID-19 cases and two others who tested positive in primary nucleic acid testing were reported in the capital on Tuesday. 

The four confirmed cases were all employees or family members of employees of a company who attended the company's training course and had just returned to the capital, Beijing health authority said at a press conference on Tuesday.

The authorities did not reveal the name of the company or where the training was held. They just revealed that they were all close contacts of cases recently confirmed in another province.   

The Global Times found that the trains the four cases took all passed Wuhan, Central China's Hubei Province, where 14 confirmed cases have been reported as of Tuesday noon. 

Ten more positive COVID-19 cases were reported on Tuesday following the first four positive cases on Monday. 13 of them participated a company's staff training held from February 18 to 20, Wuhan authorities said at Tuesday's press conference.

The four new cases in Beijing include one in Haidian District, one in Xicheng District and two in Fengtai District. 

They all received nucleic acid testing on February 16 before returning to Beijing and the results were negative, but the results of their testing after arriving in Beijing on Tuesday turned out to be positive.

The two cases that tested primarily positive for COVID-19 are a couple from the Beijing economic and technology development zone, according to Zheng Haitao, a health official from the zone.

The community where the couple lives has been closed and mass nucleic acid testing has been carried out, according Zheng.

There are also 80 students living in the community. The local health authority is communicating with involved schools over teaching arrangements, according to Zheng.
