A83.2
Eastern equine encephalitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Eastern Equine Encephalitis (EEE) is a rare but serious viral infection that affects the brain and spinal cord. Caused by the Eastern equine encephalitis virus, it primarily occurs in parts of North and South America. The infection is transmitted through mosquito bites and can lead to severe neurological complications. Recognizing the symptoms and understanding the causes is crucial for prompt medical attention and management.
Causes & Symptoms
Clinical Causes: Transmission through the bite of infected mosquitoes, particularly Culiseta melanura species The virus primarily circulates among bird populations, acting as reservoirs Occasional transmission to humans when bitten by infected mosquitoes Factors such as increased mosquito activity during warm months and stagnant water may increase risk Limited human-to-human transmission; mainly an insect-borne disease
Key Symptoms: Sudden high fever Headache and discomfort Muscle and joint aches Nausea and vomiting Sensitivity to light (photophobia) Altered mental state, confusion, or drowsiness Seizures in severe cases Neck stiffness Loss of coordination or balance In some cases, coma
Diagnostic & Treatment
Diagnosis Path: Blood tests to detect specific antibodies (IgM and IgG) Cerebrospinal fluid analysis through lumbar puncture Neuroimaging techniques like MRI or CT scans to assess brain inflammation Polymerase chain reaction (PCR) tests to identify viral genetic material
Treatment Protocols: Hospitilization for close monitoring Intravenous fluids to prevent dehydration Medications to control seizures if they occur Supportive therapy such as physical therapy for neurological deficits Management of increased intracranial pressure if present Prevention strategies to reduce mosquito exposure
