There are many ways to get infected with hepatitis B. In China, the most common is mother-to-child transmission, which means that mothers or fathers who have hepatitis B and are highly infected with the virus can transmit the virus to the next generation by giving birth to a child, in addition to hepatitis B. The disease can be transmitted through the following ways, such as intravenous injection products. In addition, hepatitis B can be transmitted through such means as intravenous injections, and also through close contact, such as using an electric razor with blood from a hepatitis B patient, which is also very likely to cause hepatitis B infection. Hepatitis B can also be spread through the digestive system, and the potential for that with meals is widespread, as well as through medical routes, such as when medical equipment is not completely sterilized.
Hepatitis B can be transmitted in several ways: primarily the infection is spread by blood night and direct blood entry, and by damaged skin and mucous membranes. At first it was transmitted intravenously, for example, by blood and various blood products. However, in recent years our country has created a system of screening of blood donors for hepatitis B surface antigen, so that intravenous transmission has been significantly reduced. There is also medical transmission, in the Hepatitis B trend there are a lot of injections or a small amount of blood caused by the night, such as injection, surgical treatment, blood extraction, extraction of teeth, endoscopy and a variety of needles (such as tattoos), and even the hands of the workers can be transmitted to Hepatitis B, which is also a pathway. Another route that is more commonly used today is mother-to-child transmission. Mother-to-child transmission is from a mother with hepatitis B to her newborn baby, especially if the transmission is mainly intrauterine or after the mother gives birth.
If the pregnant mother brings the hepatitis B virus infection, according to the birth door to the newborn baby vertical transmission, the end of pregnancy hepatitis disease of pregnant mothers to the baby's sense of seven, mother-to-child transmission is mainly by the embryo infection and its delivery process of the baby inhaled with hepatitis B virus infection of the mother's blood, pregnant women amniotic fluid and vaginal secretion and was infected, and at the same time: the first, it is very likely that the baby through the damaged skin or mucous membranes infection. or mucous membrane infection, the baby is likely to be infected by deeper contact with the mother with hepatitis B. Second, the blood night transmission, such as the key into the infected whole blood, blood, serum protein or other blood products or other blood night injection transmission in the understanding with the patient with hepatitis B, should pay special attention to not have to have blood night with the patient with hepatitis B on the touch.
Hepatitis B is mainly transmitted according to the blood night route, including medical transmission and vertical transmission from mother to child. General touch is not easy to infect, such as in the same classroom learning training, the same personnel work, the same table meals, embracing, shaking hands are not easy to infect, therefore should be injected into the hepatitis B vaccine, can prevent the infection of hepatitis B, but injected into the hepatitis B vaccine is not 100%, injected into the hepatitis B vaccine should be repeated after the diagnosis is not caused by the hepatitis B surface antibody.
