"Hepatitis" means inflammation of the liver and refers to a group of viral infections that affect the liver. The most common types of hepatic viral infections are hepatitis A (HAV), hepatitis B (HBV), and hepatitis C (HCV) infections.
HBV and HCV are bloodborne pathogens, which means they are primarily transmitted through blood and can cause disease.
HAV is not considered a bloodborne pathogen. HAV's main mode of transmission is the fecal-oral route and may be introduced into the body through ingestion of contaminated water or food.
