The hepatitis B infection is potentially life-threatening. It can cause chronic infection that can lead to cirrhosis and liver cancer. Research has shown that 70% patients of hepatitis C develop chronic liver disease and up to 20% develop cirrhosis. On the other hand, although hepatitis A is highly contagious, it is a short-term liver infection and in most of the cases the patient gets cured on his or her own and even develops an immunity (against hepatitis A variant only) after getting the infection.
