[|Human|] Hello Sir,I am from Bangladesh and my name is Mahmud Hossain. I want to know that my father is hospitalized for last 18 days for liver cirrhosis disease and here I am look after him so is there any risk for me about Hepatitis B or should I take any vaccine for Hepatitis B.
[|AI|]  Hello Mr Mahmud, How are you? My name is Chat Doctor.  I hope to answer your question today. Hepatitis B is a viral infection of the liver. In most patients the bodies immune system will successfully clear the hepatitis B virus and the patient will not suffer any ill effects of the infection. In a subset of patients, the virus will remain in the blood for a long time without causing disease in the patient (carrier). In a minority of patients, the virus attacks the liver and leads to cirrhosis and potentially cause cancer of the liver. I am sorry that your dad is suffering from cirrhosis, but am glad that he is being treated for this. The hepatitis B virus spreads from person to person through exchange of body fluids (blood, semen etc.) much like the AIDS virus. I understand your apprehension about caring for your dad and I appreciate your initiative to get vaccinated. Before getting vaccinated though, I would advise you to get checked for hepatitis B infection. If you have already been infected, then there is no reason to get vaccinated. If the test is negative, then I would advise you to get vaccinated at the earliest and more importantly get the booster doses till you attain a protective level of antibodies in your blood stream (>10IU). I hope your dad gets better soon, and I hope this discussion helped you. Please do not hesitate to contact me for further details. Have a great day
