What is the primary mode of transmission for viral hepatitis?

Viral hepatitis primarily spreads through fecal-oral transmission, particularly in the case of hepatitis A and hepatitis E. This mode of transmission occurs when a person ingests water or food contaminated with the feces of an infected individual. Improved sanitation and hygiene practices can significantly reduce the risk of this type of infection, which is especially crucial in areas with poor sanitation infrastructure.

In contrast, bloodborne transmission is the primary mode of transmission for hepatitis B and hepatitis C, which typically spreads through contact with infected blood. While airborne and vector-borne pathways exist for other infections, they do not apply to the viral hepatitis viruses in the same way. Understanding these transmission routes helps in designing effective prevention and control measures against viral hepatitis outbreaks.
