Navigating West Nile Virus in Arizona: Prevention and Awareness

Sept. 5, 2023

As Arizona embraces the warmth of summer, it also faces the annual threat of West Nile Virus (WNV). This mosquito-borne illness has been a concern in the state for years, highlighting the importance of understanding how to protect yourself and your loved ones. With Arizona's climate creating an ideal environment for mosquito activity, staying informed and taking preventive measures is essential to avoid potential health risks.

Understanding West Nile Virus (WNV)

West Nile Virus is transmitted through the bite of infected mosquitoes. While most individuals infected with WNV do not show symptoms, some may experience mild to severe flu-like symptoms, including fever, headache, fatigue, body aches, and occasionally a skin rash. In more severe cases, the virus can lead to encephalitis or meningitis, causing symptoms like high fever, neck stiffness, disorientation, and even paralysis.


Prevention Tips

  1. Eliminate Standing Water: Mosquitoes breed in stagnant water. Regularly empty containers that collect water, such as flower pots, bird baths, and buckets.
  2. Use Mosquito Repellent: Apply EPA-approved insect repellents containing DEET, picaridin, or oil of lemon eucalyptus to exposed skin and clothing.
  3. Wear Protective Clothing: When outdoors, wear long-sleeved shirts, long pants, and socks to minimize exposed skin.
  4. Stay Indoors During Peak Hours: Mosquitoes are most active during dawn and dusk, so try to stay indoors during these times.
  5. Protect Your Home: Use screens on windows and doors to keep mosquitoes out, and repair any tears in screens.
