What Is West Nile Virus?
9. Diagnosis
Your doctor is likely to perform a brief physical exam, but this is unlikely to be enough to reach a confirmed diagnosis. In order to diagnose West Nile fever, a blood sample will need to be taken so it can be examined to look for the antibodies that help fight the virus.
If the patient is suffering from severe symptoms, they will likely be tested for signs of encephalitis and meningitis. This can be achieved with help from an MRI scan that will help identify inflammation, while an EEG may also be used. A spinal tap may also be performed in order to help look for signs of meningitis.
