Hepatitis is liver inflammation caused by a virus. There are three main types:
Hepatitis A Virus (HAV): Spread by contaminated food or water. Also transmitted through person-to-person between household contacts or sex partners. It is usually short-term and does not cause long-term liver damage.
Hepatitis B Virus (HBV): Spread through infected bodily fluids (like blood or semen). It can cause long-term liver problems like cirrhosis or liver cancer.
Hepatitis C Virus (HCV): Spread mainly through blood (like sharing needles). It can also cause long-term liver damage.
