This was dormant before it came to light. Should I worry regarding myself/ [/INST] Hello,As per your clinical query is concerned, you need a screening test for hepatitis B infection and check your liver enzyme level.Do take the preventive step like this for future:1) Know the [HBV] status of any sexual partner. Don't engage in unprotected sex unless you're absolutely certain your partner isn't infected with HBV or any other sexually transmitted infection.2) Try to use a new latex or polyurethane condom every time you have sex if you don't know the health status of your partner.3) Try to avoid body piercing and tattooing.4) If you are traveling to a region where [hepatitis B] is common, ask your doctor about the hepatitis B vaccine in advance.It is usually given in a series of three injections over a six-month period.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Uday Nath Sahoo </s>
