It is possible to transmit hepatitis B virus in the same room. At present, hepatitis B virus is mainly transmitted through blood, sex and mother-to-child vertical pathway, and patients with triple positive, especially those in the active stage of hepatitis, have high quantitative hepatitis B virus DNA, which is highly contagious. If you don’t abstain from sex, it is very likely that the other person will be infected with the hepatitis B virus. At this time, patients with hepatitis B should be given antiviral treatment in a timely manner, and only when the viral quantities return to normal can they consider having sex. People who have sex with a person with hepatitis B should be vaccinated against hepatitis B in time to produce protective antibodies. If you are already having sex with a patient with active hepatitis B and you do not have protective antibodies, you should get an injection of hepatitis B immunoglobulin to reduce the risk of hepatitis B virus infection. At the same time, we should also pay attention to monitoring the hepatitis B five, once the hepatitis B virus should be selected according to the situation of the appropriate time and program of treatment.
