Dharamsala: Hepatitis B is a vaccine-preventable liver infection caused by the hepatitis B virus (HBV). Hepatitis B is spread when blood, semen, or other body fluids from a person infected with the virus enters the body of someone who is not infected. Considering the importance of regular medical evaluation every 6-12 months to assess the liver health and need for antiviral therapy to the Hepatitis B positive patients, the Department of Health, CTA conducts biannual Hepatitis B follow up tests to patients who are on antiviral therapy and annually for those who are not on antiviral therapy. On 16th and 17th November, a total of 92 HBV-positive patients have been tested for five Laboratory evaluations which will be followed by USG screening and medical consultation.
