Doctor,My friend is international student studying in Germany, He just got result from blood test with positive HBs. What should he do now? He will be expelled from Germany to his home country for treating or received treatment in Germany? Looking forward to hearing from you.All the best,VAN  <response>: Thank you for posting query at Chat Doctor.Bag positive without further evaluation can not be advice treatment. Your friend also needs to check his liver enzymes LFT, Head, and viral load PCR test. Results of all these together with Bag will give a clear picture for treatment. It is possible that the virus remains in dormant phase throughout and causes no harm to liver. Only one fourth of patients infected with Herb virus develop liver cirrhosis. Therefore, one cannot be sure about your friend status. The viral load should be monitored, and he needs to repeat test every 6 month or at least once a year. Meanwhile, people close to your friend needs to be vaccinated and also test for Bag. Advice for friend:if increased liver enzymesabstinence from Alcohol and Chat Doctor. - use lemon juice lemonade once in a day-walk 30 to 40 minutes every day.- or swimming is alternative to walking-NO sports and NO jogging-recheck liver enzymes after 6 to 8 weeks.if any further questions, feel free to ask.
