Some people in life are more susceptible to hepatitis B virus infection, such as children, middle-aged and elderly people, pregnant women, etc. These people are more prone to hepatitis B virus infection due to their weaker body resistance. In addition, medical personnel, people who frequently receive blood transfusions or blood products, organ transplant patients, and people with multiple sexual partners are also high-risk groups for hepatitis B infection, and they must pay more attention to preventive measures for hepatitis B.

　　 People are not new to hepatitis B, This disease can cause discomfort symptoms such as fatigue, decreased appetite, and abdominal pain.

Who are the high-risk groups of hepatitis B infection?
　　I. Children
　　Children’s livers are richer in blood supply than adults, and their liver cell series capabilities are also stronger, but their defense systems are not mature. , Can not remove the invading hepatitis virus in time, and it is also easy to produce immune tolerance.

In addition, with the aging of liver cells, once the liver is damaged, it is difficult to recover quickly, and the body''s immune system also declines. Therefore, the middle-aged and elderly people are also infected with hepatitis B High-risk groups.
　　Three, pregnant women
　　Pregnant women are more likely to be infected with hepatitis B than other women. This is because after pregnancy, due to the needs of fetal growth and development, the mother should provide the fetus enough Nutrition, which has caused the burden on the liver of pregnant women to become heavier, and their ability to resist disease has also decreased significantly, making them more susceptible to hepatitis B virus infection.
　　Four, other people
