West Nile Virus Information for Physicians

West Nile virus (WNV) has been detected in many regions of the state. Physicians should:

  • Be aware if WNV is active in their area
  • Look for symptoms of WNV
  • Test for WNV because testing:
    • differentiates WNV from other conditions (enterovirus, other arboviral diseases) and thus may prompt a change in treatment regime
    • results offer anticipatory guidance--both WNV neuroinvasive disease and WN fever patients can have lingering symptoms and knowing the underlying etiology is helpful for the patient and family members
    • helps mosquito control and public health agencies institute proper control measures to reduce the risk of further cases in the event of a positive result
  • Contact their local public health department for details on sample submission and testing
