　　The Office of the Leading Group for Joint Prevention and Control of Epidemic Situation in COVID-19, Qinzhou District has conducted an epidemiological survey on the activity tracks of Zhang Moumou, Zhang and He as required, tracked and controlled the people who came into contact with them, and adopted measures such as closed management and disinfection of related places.

　　At present, the domestic epidemic situation is severe and tense, and many provinces distribute local cases. Fighting the epidemic requires the support, cooperation and participation of the general public and friends. Here, I would like to remind the general public and friends:

　　One: immediately report for testing. People inside and outside the city who intersect with the trajectory of confirmed cases should take the initiative to report to their communities and units, and cooperate with communities and disease control institutions to actively implement control measures such as nucleic acid detection, isolation monitoring and health monitoring. Especially on October 24, 2021 — On October 26, the relevant personnel who had contact with the confirmed cases during the voluntary activities of nucleic acid sampling immediately reported to the CDC and took the initiative to report to the community for rapid nucleic acid testing.

　　Two: strict health observation. Observe personal health closely. If you have symptoms such as fever, dry cough, fatigue, decreased sense of smell and taste, nasal congestion, runny nose, sore throat, conjunctivitis, myalgia and diarrhea, please go to a fever clinic or a designated medical institution immediately, and truthfully inform your personal residence history. Wear a mask all the way.

　　Three: do a good job of personal protection. According to the arrangement of the provincial and municipal leading group offices for epidemic prevention and control, the general public should actively participate in the work of group prevention and control, consciously obey and abide by the community epidemic prevention regulations, implement normalized epidemic prevention and control measures, take the initiative to do personal protection, correctly regulate the wearing of masks, do not go out unless necessary, insist on frequent hand washing, frequent ventilation, no bunching, no gathering, no belief in rumors, and keep the "1 meter" safe.
