Patient's question:
How great is the infectiousness of hepatitis B with a large positive? How should hepatitis B with a large positive be treated?Doctor's answer:
The infectiousness of hepatitis B with a large positive index is relatively strong, but the main routes of infection are still blood transmission, horizontal transmission (mother-to-child transmission or father-to-child transmission), iatrogenic transmission, and sexual transmission. General daily contact will never easily lead to infection. If the alanine aminotransferase (ALT) level is elevated but below twice the normal upper limit, and the HBV-DNA level is below 10^5, antiviral treatment should be administered. If these treatment criteria are not met, no drug treatment is necessary, and regular follow-up tests are sufficient.
