Don't panic after receiving the notice of home quarantine Recently, Ms. Liu's colleague was confirmed as a confirmed case of COVID-19. As a close contact person on the same floor, Ms. Liu received a notice from the staff in the area under her jurisdiction, asking them to conduct home quarantine. "I was at work at that time. I was very nervous when I put down the phone and soon began to worry. What should I do with my children and husband? What should I pay attention to when I go home for isolation?" Ms. Liu said she was at a loss. Fortunately, the community staff communicated with Ms. Liu in a timely manner. Recently, affected by the epidemic, some residents, like Ms. Liu, have confirmed cases in their communities or units. As secret contacts, they have received the notification of home isolation and home health monitoring from the epidemic prevention and control headquarters and the community. The Party Shuangsuo explained the necessity of home isolation: "Home isolation is one of the means to prevent and control infectious diseases, which can help us reduce the risk of viral infection. If symptoms occur, we can receive treatment at the first time, and at the same time, reduce the scope of viral infection to ensure our own safety. From a social perspective, home isolation can reduce the risk of transmission to others, reduce the waste of human resources, medical and other resources, and reduce the harm to society. Therefore, home isolation is necessary, but also the first We hope that everyone will consciously abide by and protect their own and others' safety.

With regard to the issues concerned by these citizens, Dang Shuangsuo said that it is better for isolated medical observers at home to live alone. If conditions do not allow them to live with their families, they should have a single room with good ventilation. They should try to use a separate toilet. Daily life and meals should be limited to isolated rooms as much as possible to maintain relative independence, and tables and stools should be placed in the isolation room as a non-contact transfer place. Contact with other family members should be minimized. If contact is necessary, keep a distance of more than 1 meter. It is required to wear medical surgical masks. Keep hands clean at all times, avoid direct contact with body secretions, and do not share anything that may cause indirect contact with infection. Refuse all visits. If they live together with their families, they should promise to live together and isolate, not go out, and refuse to receive guests. It is better to fix a family member to take care of them, who should be in good health and free from chronic diseases. In terms of indoor cleaning, if you live with your family, you should stop using the central air conditioner and keep the isolated room closed at any time. Before opening the door of the isolated room, you should open the window for ventilation before opening the door. Open windows frequently for ventilation, at least once every 2-4 hours, 20-30 minutes each time. Ensure that the spaces to be shared, such as kitchens and bathrooms, are well ventilated (keep windows open). When you live at home, you should make a good living
