What is a key prevention method for Hepatitis A?

Hand washing is a key prevention method for Hepatitis A because this virus is primarily spread through the fecal-oral route. This can occur when an infected person does not wash their hands properly after using the restroom and then handles food or food-contact surfaces. By thoroughly washing hands with soap and water, especially after using the bathroom and before handling food, the risk of transmitting the virus can be significantly reduced.

Cooking food thoroughly, while important for many foodborne illnesses, does not directly prevent Hepatitis A, as the virus can be present in foods that are not heated or cooked. Using antibacterial soap is effective for general hygiene but may not have a significant impact specifically on viral pathogens like Hepatitis A. Refrigerating food is crucial for preventing bacterial growth but does not specifically target the prevention of Hepatitis A, since the virus can survive even in refrigerated environments.
