Why can Shanghai achieve accurate prevention and control?

Because Shanghai can adhere to the prevention of people and things and highlight the three stresses, it can achieve accurate prevention and control.

The first is to implement measures. Strict closed-loop management chain, strengthening the investigation and rectification of hidden dangers, regular nucleic acid testing for key populations, and some units may test once a month. According to this situation, it is necessary to increase the density in advance.

Second, we must pay attention to emergency preparedness and achieve "four mornings and five mornings".

Third, pay attention to personal protection. Adhere to the "three-piece suit"-wearing a mask, social distance, personal hygiene, and "five requirements"-wearing a mask, keeping a social distance, coughing and sneezing, washing hands frequently, and opening windows as much as possible.

Why should we insist on "four mornings" in the prevention and control of normalized epidemic situation;

Early detection, early reporting, early isolation and early treatment are the key measures to control the epidemic of infectious diseases, referred to as "four early". There must be three basic links in the spread of infectious diseases among people: the source of infection, the route of transmission and the susceptible population. Without any of these links, new infections and epidemics will not be formed. Therefore, the prevention and control measures of infectious diseases can be divided into three categories, namely, controlling the source of infection, cutting off the route of transmission and protecting susceptible people. ?

The source of infection refers to people and animals that carry bacteria, viruses or parasites that can cause diseases and infect other individuals. The main sources of infection in COVID-19 are COVID-19 patients and asymptomatic infected people. Adhere to the "four mornings", that is, early detection, early reporting, early isolation and early treatment of patients and asymptomatic infected people, in order to prevent a wider epidemic and protect the health of a wider population; At the same time, through the "four mornings", patients are found and treated in time to minimize the damage of the epidemic to people's life safety and health. ?

For individuals, we should raise the awareness of disease risk, seek medical advice in time if there are suspicious symptoms of COVID-19, especially those who have a history of party, business trip, travel and other suspicious exposures, and be more vigilant.
