Overview
West Nile virus (WNV) causes West Nile disease (WND), potentially leading to meningitis or encephalitis. 1Diagnosis
Serological testing (IgM and IgG antibodies) is crucial for confirming WNV infection.
RT-PCR from blood or cerebrospinal fluid (CSF) can detect viral RNA early in the course of illness.
CSF analysis may show pleocytosis and elevated protein levels in neuroinvasive cases. 1Management
No specific antiviral therapy is universally recommended; supportive care is primary.
Management includes hydration, pain control, and monitoring for complications such as seizures or respiratory failure.
In severe cases, hospitalization with intensive care support may be necessary. 1Special Populations
Pregnancy: Limited data; management focuses on supportive care with close monitoring of maternal and fetal status. 1
Pediatrics: Children may present with atypical symptoms; supportive care tailored to age-specific needs is essential. 1
Elderly: Higher risk of severe neuroinvasive disease; vigilant monitoring and intensive supportive care are critical. 1
Comorbidities: Patients with underlying conditions like immunosuppression require heightened vigilance and possibly prolonged monitoring. 1Key Recommendations
Utilize serological testing (IgM/IgG antibodies) and RT-PCR for diagnosis of WNV infection. (Evidence: Moderate) 1
Provide comprehensive supportive care including hydration, pain management, and intensive monitoring for severe cases. (Evidence: Expert opinion) 1
Tailor management strategies in special populations such as pregnant women, children, and the elderly, focusing on close monitoring and age/condition-appropriate interventions. (Evidence: Expert opinion) 1References
