What is the most common route of Hepatitis A transmission?

Hepatitis A is primarily transmitted through the fecal-oral route, which involves ingestion of the virus via contaminated food and water. The most common means of this transmission is through contaminated water sources, particularly in areas where sanitation is inadequate. When individuals consume water that has been contaminated by fecal matter containing the virus, they can become infected.

While foodborne illness is also a significant concern in Hepatitis A transmission, the more direct and prevalent route, especially in outbreaks, has been linked to contaminated water. This is why the correct choice aligns with the understanding of how Hepatitis A spreads within populations.
