Methods to prevent infectious diseases

1, control the source of infection: isolate or actively treat the source of infection to prevent the source of infection from spreading pathogens. For example, the source of hepatitis B infection is hepatitis B virus infection or hepatitis B virus carrier. In order to prevent the spread, these people should be given standardized and timely antiviral treatment, thus reducing the infectivity.

2. Control the route of transmission: pay attention to personal hygiene and environmental hygiene, and disinfect special routes of infection. For example, in the current COVID-19 epidemic, people should wear masks, go to crowded places less, and disinfect places where cases have been.

3. Protect the susceptible population: improve the specific immunity of the susceptible population. For example, to form immunity, people should be vaccinated with COVID-19 vaccine.

In a word, comprehensive measures are needed to prevent infectious diseases, including controlling the source of infection, cutting off the route of transmission, protecting susceptible people and improving living habits. Only by comprehensively and scientifically preventing infectious diseases can we effectively protect the health of ourselves and others.
