Hepatitis B carriers, that is, hepatitis B virus carriers, are divided into broad and narrow sense, as follows: Broadly speaking, all patients who are infected with hepatitis B virus and positive hepatitis B surface antigen (HBsAg) indicates the presence of hepatitis B virus within are hepatitis B virus carriers, including acute hepatitis B patients, chronic hepatitis B patients, asymptomatic virus carriers, etc. In a narrow sense, hepatitis B carriers are those who are infected with the hepatitis B virus but have no signs and symptoms of hepatitis, and whose hepatitis B surface anti-positive status persists for more than six months, and whose liver function indicators are normal, i.e. asymptomatic virus carriers. Such patients can still have hepatitis B virus in their liver cells, but replication has stopped and the virus is no longer released into the bloodstream. If the patient has normal liver function, negative hepatitis B virus DNA, no obvious abnormalities in ultrasound examination, and liver puncture examination indicating liver tissue inflammation score less than 4, the patient’s condition is apparently stable and no treatment is needed for the time being. However, asymptomatic virus carriers do not mean absolute safety, because the hepatitis B virus still exists in the patient’s body, once the hepatitis B virus enters the replication stage, it will also lead to gradual damage to the patient’s liver, which may develop into hepatitis, cirrhosis, or even liver cancer. Therefore, such patients need to be reviewed regularly to keep an eye on the dynamics of the virus in their bodies to avoid serious consequences. Therefore, hepatitis B virus carriers with symptoms must be actively treated to reduce infectiousness and improve liver function, while asymptomatic patients should be regularly reviewed to avoid delaying the disease.
