Management of Coxsackie Virus Infection in Children
No specific antiviral treatment is recommended for Coxsackie virus (enterovirus) infections in children, as most cases are self-limiting and require only supportive care. 1
Clinical Approach
The management strategy depends on the clinical presentation and severity:
Mild Disease (Hand-Foot-Mouth Disease, Viral Syndrome)
- Supportive care only - hydration, antipyretics, and symptom management
- Most cases resolve spontaneously within 7-10 days 2
- No antiviral therapy indicated
Severe Disease (Meningoencephalitis, Myocarditis)
For enterovirus meningoencephalitis, no specific treatment is routinely recommended 1. However, in severe cases, two therapeutic options may be considered:
Pleconaril (if available): An antiviral that inhibits enterovirus binding to cellular receptors. It has shown efficacy in reducing symptoms of aseptic meningitis by approximately 2 days in clinical trials, but has not been studied specifically for encephalitis and is often unavailable 1
Intravenous immunoglobulin (IVIG): May be worth considering in severe disease, particularly in immunocompromised patients 1. Case reports support its use in protracted Coxsackie meningoencephalitis with documented clinical, EEG, and CSF improvement 3
Key Clinical Considerations
Suspect Coxsackie virus infection when:
- Neonatal meningitis or myocarditis occurs with gastrointestinal symptoms
- Illness occurs during hot season (July-October)
- Recent febrile illness in household contacts 4
Transfer to pediatric neurology unit if:
- Diagnosis not rapidly established
- Patient fails to improve with supportive therapy
- Transfer should occur within 24 hours of being requested 1
Important Caveats
The evidence base for specific treatments remains weak. While IVIG showed dramatic response in one case report 3, this represents low-quality evidence. The guideline explicitly states sparse evidence exists for inpatient management of enterovirus encephalitis 1. In the absence of strong evidence for intervention, supportive care remains the standard approach for immunocompetent children.
