Hepatitis is an inflammation of the liver, a vital organ that processes nutrients, filters the blood and fights infections. When the liver is inflamed, or damaged, its functions can be affected.

Hepatitis is commonly caused by a viral infection, but toxins, certain drugs, alcoholism and bacterial infections can also cause hepatitis.

Chronic Hepatitis B can develop into a serious disease resulting in long-term health problems, including liver damage, liver failure, liver cancer and even death.

Every 30 seconds, someone dies from a viral hepatitis-related illness. More than 350 million people live with viral hepatitis and nine in ten people are unaware of their diagnosis.

Viral hepatitis types A, B, C, D and E can cause infection and subsequent liver inflammation that can lead to serious diseases, including the aforementioned liver cancer or death.

People who contract Hepatitis A and E most recover with supportive care.
