Which statement about hepatitis A sources is true?

Which statement about hepatitis A sources is true?

• A. Transmitted primarily through contaminated food and water.
• B. Transmitted by mosquito bites.
• C. Transmitted only through blood.
• D. Not associated with food or water.

Answer: (A)

Hepatitis A is spread mainly through the fecal-oral route, so the typical sources are contaminated food and water. This happens when an infected person handles food or when water supplies or shellfish become contaminated with the virus. Mosquito bites do not transmit hepatitis A, and it is not a disease transmitted only through blood. So identifying contaminated food or water as the primary source best reflects how hepatitis A spreads.
