Can congenital second liver infect

summary

There is a classmate in the dormitory, who was found to have hepatitis B during the physical examination, or congenital. We live together and are very worried about the infection. After understanding this kind of knowledge, will congenital hepatitis B be infectious?

Can congenital second liver infect

First, the routes of transmission of hepatitis B include: 1. Blood and body fluids with hepatitis B virus {HBV} are transmitted through blood transfusion, injection or contaminated skin / mucous membrane; 2. Mother to child transmission; 3. Sexual transmission; 4. General life contact {such as hugging and sleeping together}. Eating together {except oral damage} and mosquito bites are not transmitted

Second, at present, the most widely spread route in China is non injection route, such as mother to child transmission and close contact. However, injection, skin test, acupuncture, surgery, facial examination, endoscopy, public razor, ear hole and other transmission without disinfection or insufficient disinfection also account for a considerable proportion

Third, congenital hepatitis B is also infected with hepatitis B virus, and as long as there is the existence of hepatitis B virus, infectious will not disappear. Therefore, hepatitis B is infectious in any case, unless cured, infectious will disappear with the disappearance of hepatitis B.

matters needing attention

Children generally receive vaccination from birth, but the antibody will also disappear, so you can regularly do two pairs and a half of hepatitis B examination, if the antibody disappears, it is necessary to inject hepatitis B vaccine again in time.
