What happened to the epidemic?

It means the occurrence and spread of epidemic diseases.

Epidemic situation, Chinese vocabulary, refers to the occurrence and development of epidemic diseases.

There are severe acute respiratory syndrome (SARS), influenza A H 1N 1 and novel coronavirus (coronavirus pneumonia-19).

Preventive measures:

The general preventive measures before infectious diseases occur mainly include: strengthening the management of the external environment where pathogens may exist (such as "three tubes and one extermination"); Do a good job in planned immunization to protect susceptible people; Through the regular health examination of key populations (such as the regular health examination of employees in kindergartens, restaurants, drinking water and service industries), the pathogen carriers can be found in time; Carry out health education and so on.

Due to the destruction of sanitary facilities, poor environmental sanitation conditions, difficult supply of living materials, and the decline of residents' physical resistance, the probability of occurrence and epidemic of various infectious diseases has greatly increased, so general preventive measures should be strengthened.
