How to analyze the implementation and embodiment of three-level preventive measures in combination with the epidemic situation in COVID-19?

Tertiary prevention is aimed at the clinical stage of the disease and also at the outcome stage. It should be implemented in infected people with obvious symptoms to reduce the severity of acute symptoms and sequelae of the disease. The third-level protection measures should be symptomatic treatment, reduce pain and adverse reactions, buy time for a better treatment plan and improve the survival rate.

People waiting for treatment at home for various reasons, people who have been diagnosed or highly suspected, should take three-level prevention. For example, the clinical drugs currently used, as well as the antibodies in the plasma of recovered novel coronavirus patients, are all tertiary preventive measures.

In epidemiology, prevention is divided into three levels, and each level has different measures for different people. They are:

① Primary prevention: also called etiological prevention. Measures: personal health education, vaccination, premarital examination and chemical prevention;

② Secondary prevention: the "three early" prevention work of early detection, early diagnosis, early treatment, early reporting and early isolation of infectious diseases, namely "five early";

③ Tertiary prevention: Take timely and effective treatment measures for people with certain diseases to promote functional recovery.
