Chronic hepatitis B and C both cause cirrhosis of the liver and liver cancer, according to WebMD. Hepatitis B is more commonly acute than chronic, while the opposite is true for Hepatitis C. There is a vaccine for hepatitis B, but no vaccine is available for Hepatitis C, says Healthline.
Hepatitis A is the least dangerous of all forms of hepatitis. Hepatitis A will often get better on its own and will not lead to chronic liver inflammation. Hepatitis D only occurs in individuals with active Hepatitis B. Hepatitis E is most common in Africa, Asia, Mexico and India and does not lead to liver problems, reports WebMD.
Hepatitis B is more likely to be spread by sexual contact or from mother to child during the birth process, according to Healthline. It is also a concern for kidney patients undergoing hemodialysis. Hepatitis C is transmissible through blood and less often through sexual contact or during birth. The most common way Hepatitis C is spread in the United States is through current intravenous drug users. Of the estimated 3.2 million people in the United States infected with chronic Hepatitis C, most do not show symptoms of the illness, as stated by the Centers for Disease Control and Prevention.
