What is a common symptom of West Nile Virus infection?

Fever, headache, and body aches are classic symptoms associated with West Nile Virus infection. This virus is primarily transmitted through the bites of infected mosquitoes, and while many infected individuals may be asymptomatic, those who do develop symptoms often experience the flu-like signs indicated in the correct answer. The fever is typically mild to moderate and often accompanied by other discomforts such as headaches and muscle or joint pains, which align with the typical clinical presentation of the illness.

The other symptoms listed in the other options, while they may occur in various illnesses, are not representative of the hallmark symptoms associated with West Nile Virus. For instance, extreme fatigue and shortness of breath can occur due to numerous other conditions, but they are not specifically tied to West Nile Virus. Similarly, nausea and vomiting can be symptoms of many other viral infections, and chronic cough and fever are not characteristic of West Nile Virus, which more commonly presents with neurological symptoms in severe cases. Thus, the combination of fever, headache, and body aches is the most indicative of West Nile Virus infection.
