What type of symptoms may occur with West Nile virus infection?

West Nile virus is primarily transmitted through the bite of infected mosquitoes and can lead to a range of symptoms in humans. The most common symptoms associated with West Nile virus infection include fever, headache, body aches, joint pain, and, in more severe cases, neurological conditions such as meningitis or encephalitis. The presence of fever indicates the body is responding to the infection, while meningitis represents a serious complication that can arise from the virus affecting the central nervous system.

Understanding the progression from mild symptoms to severe manifestations, such as meningitis, highlights the risks involved with West Nile virus. The other symptoms listed, such as severe abdominal pain, skin rashes, hives, or respiratory symptoms like cough and congestion, are not typical presentations of West Nile virus infection and are more commonly associated with other illnesses or conditions. Therefore, the presence of fever and the potential for developing meningitis are key indicators of West Nile virus, making this response the most accurate choice.
