Different types of viral hepatitis have different routes and methods of transmission. Hepatitis A and E are mainly transmitted through the fecal-oral route via the digestive tract. Hepatitis B and C are transmitted through blood, sexual contact, and from mother to child. Generally, transmission through casual contact is rare. Most cases of hepatitis B are transmitted from mother to child. Hepatitis C is more commonly transmitted through needle stick injuries and blood transfusions.
