Breastfeeding is usually possible with a viral DNA load of less than 50. The main ways of hepatitis B transmission are blood transmission, mother-to-child transmission and sexual contact, so if you are simply breastfeeding, it usually does not lead to hepatitis B virus transmission. And with a viral DNA load of less than 50, the effects of hepatitis B are relatively minor. So it is less likely that hepatitis B carriers will spread the hepatitis B virus through breastfeeding. However, it is recommended that babies get hepatitis B vaccine in time after birth, and can be co-injected with hepatitis B immunoglobulin under the guidance of the doctor, which can play a role in blocking mother-to-child transmission. However, hepatitis B is a chronic infectious disease, which will seriously threaten the health of our people and may also lead to hepatitis, liver fibrosis, cirrhosis and liver cancer. Therefore, if you are a hepatitis B carrier, try to go for a liver checkup every six months.
