Which symptom is commonly associated with West Nile virus infection?

The symptom commonly associated with West Nile virus infection is the presence of skin rashes. In many cases, individuals infected with West Nile virus may experience a range of clinical manifestations, including but not limited to mild febrile illness and, in some cases, skin rashes which can appear as maculopapular lesions.

The typical symptoms of West Nile virus often manifest 3 to 14 days after exposure; this may include fever, headache, body aches, and in some instances, skin rashes can be a relevant clinical feature. In severe cases, neurological symptoms may also develop, such as encephalitis or meningitis, but rashes are specifically noted in many cases of milder infection.

The other symptoms listed, while they may be associated with a variety of other illnesses, are not typically highlighted as common indicators of West Nile virus infection. Recognizing skin rashes in the context of West Nile virus can assist in early diagnosis and prompt consideration of potential interventions and monitoring, particularly in areas where the virus is known to circulate.
