Hello: Chronic hepatitis B is contagious, but it is generally not contagious, and it is generally transmitted mainly through the following ways. If you kiss, if you have wounds on both sides, you can be contagious.

1.Through fetal transmission, that is, the transmission of pregnant women with hepatitis B to the fetus through the placenta and to the newborn through the birth canal, this route needs the most attention, which is currently the most widespread transmission route of hepatitis B.

2.Hemodialysis patients need to be especially careful through iatrogenic transmission, in which blood with the virus is mistakenly transfused into a healthy person or injected with an inadequately sterilized medical device.

3.It is transmitted through bodily fluids, in which healthy people with damaged skin and mucous membranes come into contact with the saliva, bile and milk of people with hepatitis B.

4. Sexual contact transmission. The semen of men with hepatitis B contains the hepatitis B virus. Experiments on chimpanzees have shown that sex can transmit hepatitis B, so condoms are recommended for hepatitis B patients.

5.Close contact transmission: It mainly refers to close contact, close contact in daily life (such as using a toothbrush, towel, teacup and chopsticks, kissing, mouth-to-mouth feeding, etc.), all of which may be infected by HBV.

It is best to go to a regular hospital for a check-up to let yourself know more clearly whether you have contracted it.
