West Nile neuroinvasive disease
Quick Summary
West Nile neuroinvasive disease is a serious medical condition caused by the West Nile virus. This virus, primarily an infection of birds, can be transmitted to humans through mosquito bites. While most human infections are mild or asymptomatic, a small percentage can develop into neuroinvasive disease. This occurs when the virus affects the central nervous system, potentially leading to encephalitis (brain inflammation), meningitis (inflammation of the membranes surrounding the brain and spinal cord), or paralysis. Symptoms can include headache, fever, disorientation, and muscle weakness, and in severe cases, can be fatal. Prevention focuses on reducing mosquito exposure and controlling mosquito populations.
