Hepatitis B is contagious in nature and is transmitted in three ways: vertical transmission from mother to child, blood transmission, and sexual contact transmission. Major triple-positive means that the three test indicators of hepatitis B surface antigen, hepatitis B e antigen and hepatitis B core antibody are all positive in hepatitis B two-to-one half. Hepatitis B major triple-positive means that the hepatitis B virus is actively replicating and highly infectious. Hepatitis B can be prevented by vaccination with the hepatitis B vaccine to stimulate the person’s body to produce enough antibodies to prevent infection with the hepatitis B virus. Hepatitis B virus infection can be determined by taking a blood test to determine the five hepatitis B tests.

The general population can be vaccinated against hepatitis B to stimulate the body’s immune system to produce antibodies and eliminate the hepatitis B virus from the body. In conclusion, hepatitis B is contagious and is transmitted through blood, sexual intercourse and vertical transmission from mother to child. Pay more attention in your daily life to avoid getting infected with the hepatitis B virus.
