Dandong City Health Service Center response: Although the number of cases of hepatitis A in our city increased slightly, but in a controllable range. Studies have shown that hepatitis A is closely related to the consumption of raw seafood. As a coastal city, the incidence rate of hepatitis A has been slightly higher than that of inland areas for many years.
Hepatitis A is an acute infectious disease caused by hepatitis A virus. It is a common digestive tract infectious disease. It is mainly transmitted through the fecal oral route. The onset of hepatitis A is often cyclical, with obvious seasonality. It is prone to occur frequently in winter and spring. From the 1-2 month of this year, the incidence rate of hepatitis A is slightly higher than that of the previous five years. However, there is no correlation between cases. The distribution of all the towns in the city has no obvious clustering and excludes the spread of point sources. Hepatitis A is a preventable, controllable and treatable infectious disease. It has a good prognosis. The simplest and most effective way to prevent hepatitis A is vaccination. People who have no history of hepatitis A immunization and who have not been infected with hepatitis A virus can be prevented by vaccination. In addition, the key to prevent hepatitis A is to control the disease from the mouth. To this end, we should especially remind the general public to do a good job in protection and reduce the risk of infection.
