It was found that there is family aggregation of hepatitis B infection. Through sexual and horizontal transmission, husbands can transmit to their wives and wives to their husbands, and through vertical and horizontal transmission, husbands and wives can transmit to their children. These modes of transmission are the main modes of transmission of hepatitis B. If there is a patient with hepatitis B virus infection in the family, how should the family handle it? First of all, for patients with hepatitis B infection, they need to go to the hospital for regular checkups and have their liver function tested once every six months. If the liver function indicates that the transaminases are normal, they usually only need to be observed and do not need treatment. However, if the transaminases are elevated, the patient should be seen at a specialist hospital and may need to receive liver protection or antiviral treatment. Children with hepatitis B who have elevated transaminases will require a liver puncture to determine the degree of inflammation and fibrosis in the liver tissue to determine if antiviral therapy is needed. If there is a family history of liver cancer, more aggressive treatment of hepatitis B is required. Hepatitis B patients also need to abstain from alcohol, disable liver-damaging drugs, take rest and avoid overexertion, etc. Secondly, family members who are not infected with hepatitis B virus need to be vaccinated against hepatitis B and do a good job of personal protection to avoid intra-family transmission, especially mother-to-child transmission. Supervise family members to have regular checkups and timely treatment. Do not believe in false advertisements and go to regular hospitals for treatment, etc. Hepatitis B is not terrible, as long as good protection, generally will not be infected, even if infected with hepatitis B, do not be too afraid, because hepatitis B can be prevented and treated, and is not an incurable disease.
