COVID-19 three defenses refers to which three defenses?

COVID-19's three defenses refer to civil air defense, technical defense and weapon defense.

Prevention and control strategies:

(1) Internal and external defense. Implement infection prevention and control measures based on "early detection, early reporting, early isolation and early treatment" and "close the entrance" of personnel, vehicles and materials in medical institutions.

Check the body temperature of people entering medical institutions, show their health (travel) codes, and check the wearing of masks. Do a good job in health monitoring of inpatients and caregivers, and find and deal with suspected symptoms of COVID-19 infection in time.

(2) Both doctors and patients should take precautions. All staff of medical institutions, patients and their caregivers should do personal protection, and take additional preventive measures according to the route of disease transmission on the basis of strict implementation of standard preventive measures to avoid cross-infection.

(3) People should guard against each other. It is necessary to do a good job in the protection of both doctors and patients and the early warning of infection risks, and strengthen the prevention and control of risks such as environment, articles and foreign bodies in medical institutions. Implement cleaning and disinfection measures for the environment and the surface of objects, and strengthen the cleaning and disinfection of the environment after contact with key departments and key people. Strengthen the management of foreign personnel and articles, and conduct environmental inspection when necessary.

At present, the epidemic situation of COVID-19 in the world is still severe and complicated. Due to the influence of mutant strains, the pressure of "external defense input" in China continues to increase, and related work needs to be further strengthened.
