In simple words: EIEC is a type of E. coli that causes a mild form of dysentery, like the one caused by Shigella.You get it from contaminated food or water.It causes diarrhea, fever, chills, vomiting, stomach aches, and you might not feel like eating.Usually, it gets better on its own, but some people might need antibiotics.

Infection caused by the bacterium Enteroinvasive Escherichia coli (EIEC).EIEC causes a mild form of dysentery similar to shigellosis, characterized by watery diarrhea (sometimes bloody and/or mucous), fever, chills, vomiting, stomach pain, and loss of appetite.The infection is typically acquired through ingestion of contaminated food or water.

Example 1: A 3-year-old child presents with watery diarrhea, fever, and abdominal cramps after consuming contaminated food at a picnic. Stool culture confirms EIEC infection., An elderly patient with a weakened immune system develops bloody diarrhea and fever following a trip to a developing country.EIEC is identified as the causative agent., A group of individuals experience symptoms of mild dysentery after drinking contaminated water. Laboratory tests identify EIEC in their stool samples.

Documentation should include signs and symptoms, travel history, laboratory results confirming EIEC infection, and any treatment provided.

** EIEC infection is often mistaken for Shigella infection due to similar symptoms and pathogenic mechanisms.EIEC does not produce the heat-labile (LT) and heat-stable (ST) toxins typically associated with other E. coli infections.
