The epidemic situation in COVID-19 is divided into winter and summer. If the prevention and control measures are not in place, they may make a comeback at any time. Wu Zunyou, chief epidemiologist of China CDC, said that late autumn, early winter, late winter and early spring are the frequent seasons of common respiratory infectious diseases.

As long as the COVID-19 epidemic exists in the world, it will pose a threat to the prevention and control of the epidemic in China. Outbreaks may occur at any time, but the scale is different. It depends on whether the epidemic situation can be discovered as soon as possible and whether the prevention and control measures can be fully and thoroughly implemented.

Methods to prevent epidemic situation:

1, the source of infection, it is best to find the source of infection and isolate it to prevent the spread of the virus.

2, cut off the route of transmission, if it is airborne, it is best for everyone to wear a mask to block the route of transmission. If it is spread by contact, wash your hands, clothes and hair frequently. If there is oral or intestinal transmission, everything at the entrance should be sterilized at high temperature, cooked before eating, and not eaten raw.

3. Protect vulnerable groups. In COVID-19, everyone is a susceptible group. But other diseases, such as simple pertussis, are not susceptible to everyone, and permanent antibodies have been produced after receiving vaccine treatment.
