Hepatitis virus carriers are the same as hepatitis B virus carriers. At present, viral hepatitis is mainly categorized into hepatitis A, hepatitis B, hepatitis C, hepatitis D and hepatitis E. Only hepatitis B has viral carriers, while other types of hepatitis do not. The so-called viral carriers are those who have normal liver function and positive hepatitis B DNA. Such patients are suggestive of the inactivity of the hepatitis B virus. If the liver function is not normal, its transaminase is more than twice the upper limit of normal value, and hepatitis B DNA is positive, we call hepatitis B patients, hepatitis B patients need treatment, in addition to conventional treatment such as liver preservation and lowering enzyme, antiviral treatment is also needed.
