West Nile Virus pops up in Fresno Co.

Amid reopening from coronavirus, the Fresno County Department of Public Health warns that West Nile Virus has been found in Fresno.

As California reopens from the coronavirus pandemic, the Fresno County Department of Public Health warns that West Nile Virus has been found in Fresno. 

The Consolidated Mosquito Abatement District informed the public health department that adult mosquitoes have tested positive for West Nile Virus. 


The mosquitoes were found in the 93704 zip code, which runs from McKinley to Herndon mostly between Palm and Blackstone. 

“This confirmation is a strong reminder that everyone should take this disease seriously and should take every precaution to protect themselves and their families from mosquito bites,” said Fresno County Interim Health Officer Dr. Rais Vohra. 

The department recommends that people report any standing water, mosquito problems or neglected pools to their local mosquito control district. 

The department has three guidelines – which it refers to as the “Three Ds” – to protect against mosquito bites: 

  • DEET: Apply insect repellent containing DEET, picaridin, oil of lemon eucalyptus or IR3535 according to label instructions. Rebellents keep the mosquitoes from biting you. Insect repellents should not be used on children under two months of age.  
  • Dawn and Dusk: Mosquitoes usually bite in the early morning and evening, so it is important to wear proper clothing and repellent if outside during these times. Make sure that your doors and windows have tight-fitting screens to keep out mosquitoes. Repair or replace screens that have tears or holes. 
  • Drain: Mosquitoes lay their eggs on standing water. Eliminate all sources of standing water on your property by emptying flowerpots, old car tires, buckets and other containers. If you know of a swimming pool that is not being properly maintained, please contact your local mosquito and vector control agency.
