Which of the following is listed as a complication of the West Nile virus?

Encephalitis is recognized as a serious complication of West Nile virus infection. The virus primarily spreads through mosquitoes and can infect humans leading to neurological diseases, with encephalitis being a significant manifestation. This condition involves inflammation of the brain, which can result in severe complications such as cognitive impairments, seizures, or motor function issues, making it a critical health concern associated with West Nile virus.

Chronic cough, pneumonia, and fever, while they may be associated with various infections or illnesses, are not classified specifically as complications of West Nile virus infection. Fever can occur as part of the initial symptoms of the illness but is more of a common viral symptom rather than a complication. Understanding these distinctions is crucial in recognizing the implications of the virus and its potential effects on the human neurological system.
