What is Hepatitis A primarily caused by?

Hepatitis A is primarily caused by oral transmission through fecal contamination. This viral infection is typically spread when an individual ingests food or water that has been contaminated with the feces of an infected person. The virus can survive on surfaces and in contaminated environments, making proper sanitation and hygiene crucial in preventing its spread.

Unlike other types of hepatitis, such as Hepatitis B and C, which are primarily spread through blood and bodily fluids, Hepatitis A is related to how individuals come into contact with contaminated material. This can happen in various settings, particularly where sanitation practices are inadequate. Understanding this mode of transmission is essential for implementing effective prevention strategies, such as vaccination and improved hygiene practices.
