Quick Summary

The fecal-oral route is a primary pathway for transmitting infectious diseases. This occurs when pathogens from feces contaminate food or water, which are then ingested by another person. This route is a common cause of illnesses like viral gastroenteritis, often referred to as the stomach flu.12

Pathogens responsible for foodborne illnesses include bacteria like Salmonella and viruses such as norovirus. These can spread easily, especially in areas with poor sanitation or low vaccination rates, as infected individuals can shed viruses in their stool even without showing symptoms.31
