In response to the requirements for prevention and control of the epidemic, on 15 march a third round of regional nucleic acid testing was carried out in the changgau region for key populations such as the population of the containment zone, the controlled area and persons in concentration. Among them, the results of all tests carried out in the closed and controlled areas were negative。

A positive tester was found at the central isolation medical observation site, and on 13 march a person in close contact with the non-symptomatic infected person was transferred from the van to the central isolation point。

Li, a 64-year-old male, a staff member of the chinese- and park-based chili-cooked meat shop, who lives in the chinese-based and park-based districts, was tested positive for nuclear acid on 15 march. The trajectories of li and wang are as follows: on 11 march, at 2100 hours, he returned home on an electric car after he had left work at the chili shop (china and the park shop); at 0852 hours on 12 march, on an electric car; at 1415 hours, on an electric car; at around 1620 hours, on an electric car; at 2108 hours, on 12 march, he went to the shop next to the chili, where he bought bread and then returned home on an electric car; and at 0800 hours on 13 march, he was transferred directly from his home to the isolation point。

It is hoped that the general public will increase its awareness of prevention and be firmly subject to control. If there is an intersection with the above-mentioned itinerary, please immediately inform the community (village, residence) or the cdc of your intention to cooperate in the implementation of social control measures. The public is invited to follow the official authorities, to refrain from making lies, unbeliefs and rumours, to maintain a sense of personal protection at all times, to visit the nearest fever clinic immediately in the event of heat, cough and indigence, and to inform them of the 14-day trajectories and history of exposure, to wear masks throughout the medical journey and to avoid travelling by public transport. Follow-up information will be made available to society in a timely manner。
