Viral causes of Hepatitis (Liver Inflammation! How Hepatitis C is transmitted?

The most common viral causes of hepatitis (liver inflammation) are the hepatitis A, B, and C viruses.

Hepatitis A virus (HAV) is spread by food and water contaminated with infected stools. It produces jaundice, fever, nausea, vomiting, and upper abdominal pain. Most people recover within 2 months.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) are spread by infected body fluids such as blood or semen. HBV causes acute hepatitis, which may lead to chronic hepatitis. HCV often has no symptoms initially, but may lead to chronic hepatitis. Chronic viral hepatitis may result in cirrhosis and liver cancer, but antiviral drugs can reduce the risks.

This virus is commonly transmitted by sexual contact, blood transfusion, sharing needles for Portal vein drug use, and nonsterilized tattoo equipment.
