Hepatitis is inflammation of the liver tissue. The most common cause is virus. Other causes include heavy alcohol use and certain medications. There are five main types of viral hepatitis: A,B, C, D, and E. In particular, types B and C lead to chronic disease in hundreds of lakhs of people and, together, are the most common cause of liver cirrhosis and cancer.
Hepatitis A Virus (HAV)
It is usually spread by eating food or drinking water contaminated with infected faeces. Infections are in many cases mild, with most people making a full recovery and remaining immune from further HAV infections.
Hepatitis B Virus (HBV)
It is transmitted through exposure to infective blood, semen, and other body fluids. HBV can be transmitted from infected mothers to infants at the time of birth or from family member to infant in early childhood. HBV also poses a risk to healthcare workers who sustain accidental needle stick injuries while caring for infected-HBV patients. Safe and effective vaccines are available to prevent HBV.
Hepatitis C Virus (HCV)
It is mostly transmitted through exposure to infective blood. This may happen through transfusions of HCV-contaminated blood and blood products, contaminated injections during medical procedures, and through injection drug use. There is no vaccine for HCV. Anti-viral medicines can cure more than 95% of persons with Hepatitis C infection, thereby reducing the risk of death from liver cancer and cirrhosis, but access to diagnosis and treatment is low.
