Hepatitis A is most commonly transmitted by which route?

• A. Blood transfusion
• B. Contaminated water/fecal-oral
• C. Sexual contact
• D. Airborne

Answer: (B)

Hepatitis A is transmitted mainly through the fecal-oral route, typically by ingesting water or food contaminated with an infected person’s stool. The virus can persist in the environment, leading to outbreaks in areas with poor sanitation or where untreated water is used. This route differs from other possibilities: it isn’t primarily spread by blood transfusion (that’s more relevant for hepatitis B and C), sexual transmission can occur but is less common for Hepatitis A, and it does not spread through the air.
