How to isolate the visited epidemic-related risk points?

People who live in isolation at home and live together should obey the unified management of the community (village), strictly stay at home, do not go out or visit, and cooperate with various prevention and control measures such as nucleic acid detection, antigen self-test and health monitoring; Home isolation personnel should try to choose a well-ventilated room, open windows every day for ventilation, and do a good job in ventilation and disinfection of toilets, bathrooms and other * * * enjoyment areas; Try to stay in the room where you live and eat, reduce contact with people who live with you, do not use daily necessities, keep a safe distance when touching, wear a mask and do personal protection. In COVID-19, pneumonia is a respiratory disease, which is spread through respiratory droplets and close contact. I would like to remind citizens and friends that people spend a long time in closed places in winter, which increases the risk of respiratory infectious diseases. We should avoid going to crowded places, wear masks in relatively closed places such as buses, elevators and hospitals, and keep a safe social distance. Window ventilation is one of the important means to prevent respiratory infectious diseases. Even if the weather is cold, it is necessary to open the window for ventilation at any time, and open the doors and windows to form convection to ensure indoor air circulation. When there are isolated people at home, their rooms should be closed and ventilated separately. Pay attention to cold and warmth during ventilation, especially for the elderly, children and other people with weak resistance.
