Xinhua News Agency, Chengdu, December 10 (Reporter Dong Xiaohong) At approximately 9 pm on the 10th, a press conference on epidemic prevention and control was held in Chengdu.

A total of 1,101,234 nucleic acid samples have been completed and 1,048,007 have been analyzed. Among them, 10 were positive, 1,047,997 negative and the rest of the results are pending. 818 environmental samples have been collected, of which 769 were negative and 14.
