Hepatitis B is a viral infection. It is spread through vaginal, anal and oral sex, sharing needles to inject drugs or for any other reason, and contact with infected blood. Hepatitis B can be detected through a blood test. No specific treatment exists for Hepatitis B. Supportive care should be given to the patient who has symptoms of the infection.
Some people recover completely.
Some people can never be cured. Their symptoms may go away, but they are still able to transmit the virus. It can cause chronic hepatitis, cirrhosis, liver cancer, liver failure and death. Although liver failure and death are extremely rare. No method is completely foolproof.
