Introduction
In general, viral hepatitis transmitted through the digestive tract mainly refers to hepatitis A and hepatitis E. To block the transmission of these viruses, it is essential to start with daily habits. Thoroughly wash hands with running water before meals and after using the toilet, to prevent virus contamination of food via the hands. Seafood and meat must be thoroughly cooked, as high temperatures can effectively inactivate the viruses.

Generally, viral hepatitis transmitted through the digestive tract primarily refers to hepatitis A and hepatitis E. The specific analysis is as follows:

Hepatitis A and hepatitis E are mainly transmitted via the digestive tract, with the core reason being that the transmission routes of these viruses are closely linked to the gastrointestinal system. These viruses are commonly found in the feces of infected individuals. If feces contaminate water sources, food, or tableware, the virus can enter the body through the mouth when ingested by healthy individuals, then invade the gastrointestinal tract, reach the liver, and replicate extensively. Shellfish such as clams easily accumulate these viruses; consuming them raw or undercooked directly leads to infection. Drinking untreated raw water or eating contaminated vegetables and fruits also allows the virus to enter the body through the digestive tract and cause disease.

To block the transmission of these viruses, it is essential to start with daily habits. Wash hands thoroughly with running water before meals and after using the toilet, to prevent transferring viruses from hands to food. Seafood and meat must be fully cooked, as high temperatures effectively kill the viruses. Avoid drinking raw water and ensure drinking water sources are clean and safe. Separate kitchen utensils used for raw and cooked foods to prevent cross-contamination. When dining out, choose hygienic establishments, and use serving chopsticks and spoons during group meals to reduce the risk of infection.
