    Hepatitis B Virus Infection: It is a serious contagious infection caused by the Hepatitis B virus affecting the liver. It can be an acute (an infected person may be sick for only a few days) or chronic infection (it develops slowly but progresses to a serious lifelong infection). This infection spreads from person to person through blood contact (being pricked with a contaminated needle, using a razor), intimate contact with the infected person, direct contact with infected blood, or contact with any other personal items with leftovers of infected fluid or even from mother to baby during birth. Peginterferon Alpha 2a is used to treat HBV infection.

The symptoms may not appear immediately. Some may take between 2 to 12 weeks to appear.
