The West Nile virus transmission peaks during summer through fall, coinciding with mosquito activity. This mosquito-borne illness can cause symptoms such as fever, nausea, and headaches. Approximately 20% of infected individuals experience mild symptoms, but only about 1% develop severe neurological issues affecting the central nervous system. The virus is more prevalent in northern regions, but cases have been reported across the country. Variations of the infection lead to different symptoms, including West Nile fever, neuroinvasive diseases like encephalitis, meningitis, and meningoencephalitis. Symptoms usually appear 2 to 15 days post-infection and may range from flu-like signs to severe neurological impairments. Currently, there is no targeted cure, and treatment focuses on supportive care and prevention of secondary complications.
