What is the primary source of infection for Hepatitis A?

• A. Mollusks
• B. Undercooked meat
• C. Raw vegetables
• D. Contaminated water

Answer: (A)

The primary source of infection for Hepatitis A is indeed mollusks, particularly shellfish such as clams and oysters. These marine animals can accumulate the virus when they filter-feed in contaminated water. If the mollusks are consumed raw or inadequately cooked, they can transmit the virus to humans, leading to Hepatitis A infection. While undercooked meat, raw vegetables, and contaminated water can also pose health risks, they are not the primary sources of Hepatitis A. Contaminated water is important in the transmission of the virus, especially in areas where sanitation practices are poor, but mollusks have a more direct link to outbreaks specifically related to Hepatitis A, making them the most significant source of infection.
