###Human: Is Hepatitis B a contagious disease? ###Assistant: Hi. Hepatitis B virus is transmitted through sexual contact with an infected person and through blood, mucous membranes, and wounds. Yes, other persons can use your things and drink water from your glass if they do not have any injury. You should not have sexual contact with your wife. And she should check herself for hepatitis B. Are you taking any injections for hepatitis B, like interferons? You should do the tests - HBsAg, Anti HBc and Liver Function Test (LFT). If you have already done these tests, you can upload the report here. Yes, in rare cases, it can affect a breastfed child. But, I think your wife must have been tested for hepatitis B and C before delivery. Your wife needs booster doses of hepatitis B vaccine if she had taken the vaccination during childhood. She also has to check antibodies against hepatitis B. For further queries, revert back to a general practitioner online -->
