About Viral Hepatitis

Viral hepatitis is inflammation of the liver caused by a virus. There are five different hepatitis viruses, hepatitis A, B, C, D and E. All of these viruses cause short term, or acute infection. However the hepatitis B, C and D viruses can also cause long-term infection, called chronic hepatitis, which can lead to life-threatening complications such as cirrhosis (liver scarring), liver failure, and liver cancer. Viral hepatitis kills 1.5 million people every year.
