What is a potential neurological symptom of severe West Nile virus infection?

Severe West Nile virus infection can lead to serious neurological symptoms, one of which is confusion or paralysis. This occurs because the virus can affect the central nervous system, leading to conditions such as encephalitis or meningitis. When the virus invades the brain or spinal cord, it can disrupt normal neural function, resulting in alterations in consciousness, cognitive dysfunction, and motor impairments, which may manifest as confusion or even paralysis in extreme cases. Recognizing these neurological symptoms is crucial for early diagnosis and intervention, as they indicate a more severe manifestation of the disease that requires medical attention.
