A04.2
Enteroinvasive Escherichia coli infection
Clinical Classification Guidelines
Medical Intelligence & Overview
Enteroinvasive Escherichia coli (EIEC) infection is a gastrointestinal illness caused by a special type of bacteria called Escherichia coli. This strain, classified under ICD-10 code A04.2, invades the lining of the intestines, leading to symptoms similar to other bacterial foodborne illnesses. It’s primarily transmitted through contaminated food or water and can cause outbreaks in community settings. Understanding this infection helps in recognizing its signs, causes, and the importance of proper hygiene and food safety measures.
Causes & Symptoms
Clinical Causes: Consuming undercooked or contaminated meat, especially ground beef Eating contaminated raw vegetables or fruits Consuming food prepared in unsanitary conditions Drinking contaminated water, especially in areas with poor sanitation Close contact with infected individuals or carriers
Key Symptoms: Diarrhea, often with mucus and sometimes blood Fever Abdominal cramps and pain Nausea and vomiting Fatigue and dehydration in severe cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves collecting stool samples to identify the presence of EIEC bacteria. Laboratory testing, including culture and molecular methods, helps confirm the infection. Clinical assessment of symptoms and recent exposure history supports the diagnosis. Sometimes, additional tests like blood work may be performed to evaluate dehydration or complications.
Treatment Protocols: Treatment primarily focuses on managing symptoms and preventing dehydration. Rehydration with oral or intravenous fluids is critical. Antibiotics are generally not recommended unless in severe cases or high-risk patients, as they may prolong bacterial shedding. Rest, maintaining good hygiene, and following a healthy diet aid recovery. In some cases, healthcare providers may recommend specific medications to reduce symptoms or treat complications.
