FAQ
ETEC infection is an illness caused by specific strains of E. coli bacteria that produce toxins in the intestines, leading to watery diarrhea. It is a common cause of 'traveler's diarrhea' due to consumption of contaminated food or water.
Patients diagnosed with A04.1 often experience sudden onset of watery diarrhea, abdominal cramping, nausea, and occasionally vomiting or a low-grade fever. Symptoms usually appear 1 to 3 days after exposure to the bacteria.
Diagnosis is typically based on characteristic symptoms, especially in travelers. Lab confirmation can be done through stool tests. Treatment focuses on preventing dehydration through fluid and electrolyte replacement, and antibiotics may be used in certain situations to shorten the illness.
