Big Three-yang is a kind of hepatitis B, which refers to the positive surface antigen, positive E antigen and positive core antibody in the five items of hepatitis B. The virus replication in patients with Big Three-yang is active, and the amount of virus DNA is relatively high, which is highly contagious, so it can be said that it is the most contagious of all types of hepatitis B infection. People usually have some fears about hepatitis B, which mainly comes from the infectivity of hepatitis B. In fact, the infectivity of hepatitis B is not as strong as expected. There are certain transmission routes, such as blood-to-body contact transmission and vertical transmission from mother to child. Hepatitis B virus infection can be effectively prevented by vaccination.

There are relevant documents in our country, which stipulate that if the liver function test results are normal, people infected with hepatitis B virus, including big three-positive patients, can apply for health certificates, and will not be rejected in employment and enrollment because of hepatitis B virus infection. If the liver function shows that the liver is damaged and is in the active stage of hepatitis B, you cannot apply for a health certificate. First of all, comprehensive treatment such as active anti-virus and liver protection should be carried out, and relevant documents can only be processed after the condition is stable. However, in some special industries, such as catering, food processing, preschool education, medical work and so on. Patients with hepatitis B are not allowed to apply for a health certificate, even if their liver function is normal, so patients with hepatitis B should avoid engaging in related occupations.
