The causes

More often of bacterial origin than parasitic or resulting from a virus, its transmission occurs through the fecal-oral route.

A good number of bacteria are responsible for the contamination, the best known and the most common is undeniably the enterotoxigenic Escherichia coli also known in its abbreviated form of E. coli.

The mechanism of action of the E. coli bacteria is essentially the production of an enterotoxin (a toxic substance that targets the intestines) that causes a flow of water and electrolytes into the intestinal lumen, softening the stool and leading to diarrhea3.

Other bacteria causing this disease are Salmonella, Shigella, and Campylobacter. The disease can also sometimes be caused, although less often by parasites such as Giardia, Cryptosporidium, Cyclospora or viruses such as rotavirus or norovirus1,2.
