Symptoms of ETEC include watery diarrhea, a feeling of being unwell (malaise), a low fever, and abdominal cramps.

Enterotoxigenic E. coli  (ETEC): Signs and Symptoms

ETEC produces heat-stable (sometimes heat-liable) enterotoxins and colonizations factors (adhesins) that allow it to attach to the intestinal wall. These enterotoxins are similar to the cholera toxin.
