At a news conference on the prevention and control of the COID-19 epidemic  in Beijing on June 13, Gao Xiaojun, a spokesman for the Beijing Municipal Health  Commission, said that Beijing will carry out nucleic acid testing on relevant  personnel in the Xinfadi Agricultural Wholesale Market.

　　Gao Xiaojun said that in view of the fact that confirmed cases had been  found in the Xinfadi Agricultural Wholesale Market and the environmental nucleic  acid samples showed positive result in testing, Beijing decided to carry out  nucleic acid testing on people who have been in close contact with the Xinfadi  market since May 30. The health and public security department was developing a  screening plan that will screen people on a district basis and will be announced  today for public attention. At present, there are 98 institutions with nucleic  acid testing capabilities, and the daily maximum detection capacity has reached  more than 90,000 people, which can meet the needs of the population  detection.
