hepatitis is a disease caused by which pathogen
Hepatitis Viral hepatitis is the most common type of hepatitis worldwide.[21] Viral hepatitis is caused by five different viruses (hepatitis A, B, C, D, and E).[14] Hepatitis A and hepatitis E behave similarly: they are both transmitted by the fecal–oral route, are more common in developing countries, and are self-limiting illnesses that do not lead to chronic hepatitis.[14][22][23]
