Hepatitis A acute infection is transmitted by which routes?

Hepatitis A is transmitted primarily through the fecal-oral route. Ingestion of HAV-contaminated water or food, or direct contact with an infected person who is shedding the virus in stool, leads to infection. The virus is shed in stool during acute illness, and outbreaks are often linked to poor sanitation or contaminated foods such as shellfish. This route is why hand hygiene, safe food and water practices, and vaccination are key for prevention. Airborne spread is not how HAV typically transmits, and it is not a bloodborne virus like hepatitis B or C. Sexual contact can involve fecal-oral exposure and thus potential transmission, but it is not the primary route for HAV.
