What is the primary mode of transmission for Hepatitis A?

• A. Blood transmission
• B. Needle sharing
• C. Sexual contact
• D. Fecal-oral route

Answer: (D)

The main concept here is how Hepatitis A is transmitted. It occurs primarily via the fecal-oral route. The virus is shed in the stool of an infected person and can enter another person when contaminated food or water is ingested or when hands contaminated with feces are not properly washed before touching the mouth. This is why outbreaks are common in places with poor sanitation or in situations involving contaminated food sources, like shellfish from polluted waters. Hepatitis A is not primarily spread through blood or needles, which is why routes like blood transmission or needle sharing aren’t the main pathways for this virus. Sexual contact can involve fecal-oral exposure as part of transmission, but the predominant and most typical route remains ingestion of material contaminated with feces. That’s why the fecal-oral route is the best answer.
