### output:

Thank you for posting query at Chat Doctor.Bag positive means that your have been infected with Herb virus. You need to be checked for Head and viral load to know your "infectious state".ONLY positive or high Head and/or viral load will mean that your highly infectious. 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 status. The viral load should be monitored, and he needs to repeat test every 6 month or at least once a year. Without further evaluation, you can not be advice treatment. Liver enzymes (LFT), Head, and viral load (PCR test) need to be examined. Take results to treating physician or post them at Chat Doctor for further advice. Results of all these together with Bag will give a clear picture for treatment. Meanwhile, people close to your friend needs to be vaccinated and also test for Bag. If any further questions, feel free to ask. Health professionals aim to diagnose properly and manage patients according to their limited knowledge.
