West Nile Virus: A Comprehensive Clinical and Epidemiological Framework

This comprehensive review explores the biological lifecycle, geographic spread, and clinical impact of the West Nile virus. It details how the pathogen circulates between avian populations and mosquito vectors, occasionally spilling over into humans as dead-end hosts. While many infections are asymptomatic, the text highlights severe neuroinvasive conditions such as encephalitis and paralysis, particularly in vulnerable groups. Diagnostic protocols emphasize cerebrospinal fluid analysis and advanced neuroimaging to identify central nervous system damage. Because no human vaccine exists, the sources advocate for integrated pest management and personal protective behaviors to mitigate transmission. Overall, the literature provides a definitive framework for managing the virus through environmental surveillance and supportive medical care.
