enterotoxigenic E. coli (ETEC)

Enterotoxigenic Escherichia coli (ETEC) is a type of bacteria that can cause diarrhea, often called traveler’s diarrhea. It infects the small intestine by producing toxins that stimulate excess fluid and electrolyte secretion, leading to watery stools. ETEC is commonly transmitted through contaminated food and water, especially in areas with poor sanitation. While it often causes short-term illness, it can lead to dehydration if not properly managed. ETEC is a common cause of gastrointestinal infections worldwide, particularly in developing countries, and can be prevented with good hygiene, safe food practices, and vaccines where available.
