The integration of "three defenses" refers to the integration of "civil air defense" to standardize staff behavior, strengthen behavior control, "technical defense" to improve sensory control skills and optimize diagnosis and treatment processes, and "instrument defense" to scientifically use disinfection and sterilization agents and related facilities and equipment.

Prevention and control strategy

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. For those who enter medical institutions, check their body temperature, 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. Doctor-patient prevention

All staff of medical institutions, patients and their accompanying personnel should do personal protection, and on the basis of strictly implementing standard preventive measures, take additional preventive measures according to the route of disease transmission to avoid cross-infection.

3. Defensive characters

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.
