How is Hepatitis A transmitted?

How is Hepatitis A transmitted?

• A. Contaminated food and the oral-fecal route
• B. Through contaminated blood transfusions
• C. Through droplets in the air
• D. Through sexual contact

Answer: (A)

Hepatitis A spreads mainly through the fecal-oral route, meaning the virus is shed in stool and can contaminate food, water, or surfaces. If someone ingests something contaminated—such as food prepared by an infected person who didn’t practice good hand hygiene, or water and produce in areas with poor sanitation—the virus enters the mouth and can cause infection. This is why safe food handling and thorough handwashing are key prevention steps, along with vaccination for those at risk or traveling to high‑risk areas. The virus is not transmitted through blood transfusions or typical airborne droplets, and while sexual contact can involve fecal-oral exposure, the primary and most common route is contaminated food and the oral-fecal pathway.
