The viruses, bacteria, and parasites that cause gastroenteritis are often food-borne and are considered to be types of food poisoning. They are contagious, so food poisoning from them is contagious. Food poisoning from Salmonella1, Campylobacter2, E.coli3,and norovirus4 are contagious to other people. When you are sick with one of these illnesses, your vomit and feces are full of the organism and can infect other people.
The large majority of causes (viral and bacterial) of gastroenteritis are contagious, usually through food or water contamination; in addition, they can be transferred person-to-person. A few causes are not contagious such as food allergies or the side effects of medications. Exposures to body fluids (for example, feces or droplets containing infectious agents) are common sources that transmit the disease to others (See transmission section below).
