The main route of transmission of hepatitis B is through blood and blood products, including maternal and child, skin and mucous membrane damage. Mother-to-child transmission is a very important aspect of blood transmission. At present, the number of cases transmitted through blood has decreased significantly. On the contrary, blood transmission is mainly reflected in the transmission of mothers and babies. Mother-to-child transmission mainly occurs in the perinatal period, usually at the time of delivery. At this time, because newborns have no immunity, they are prone to infection after receiving viruses in body fluids and blood. This situation is the main route of transmission of hepatitis B in our country.

In addition, transmission through mucosa is also a very important aspect. In addition, there are unclean sanitary products, pierced ears, tattoos, and hairdressing products that have not been strictly disinfected may all lead to hepatitis B infection. Another important blood and mucosal transmission is sexual transmission, which mainly occurs in unclean sex with hepatitis B virus carriers. Another important issue that people are very concerned about is whether kissing will spread.

Another question that people often mention in daily life: Will eating together cause spread? Eating together will not spread, nor will sharing tableware.
