How does hepatitis A primarily transmit?

Hepatitis A primarily transmits through contaminated food or water due to the fecal-oral route. This means that the virus is shed in the stool of an infected person and can contaminate food or water supplies if proper hygiene practices are not followed. This is particularly common in situations where sanitation is poor, or where food vendors do not take precautions—such as washing hands properly or using clean water sources. Understanding this transmission route is crucial for implementing preventive measures, especially in areas where hepatitis A is endemic or where outbreaks can occur. Other methods of transmission, like those listed in the incorrect options, are not the primary means through which hepatitis A spreads, making contaminated food or water the focal point for understanding its transmission dynamics.
