Public Health Notification: West Nile Virus Detected in Visalia

VISALIA, CA – West Nile Virus has been detected in Visalia and Tulare County Health & Human Services and Delta Vector Control District want community members to use safety precautions as we approach the Memorial Day holiday.

Delta Vector Control District (DVC) has advised that West Nile Virus (WNV) has been detected in mosquitoes at three different locations in South Visalia. DVC indicates that trap counts are much larger this year than in 2016, likely due to a wet winter, and incidents of mosquitoes carrying WNV will continue to rise as temperatures increase. DVC is actively engaged in surveillance and control of mosquito populations, using 172 sites throughout Visalia, Dinuba, Cutler, Orosi, Farmersville, Exeter, Ivanhoe, Goshen, and Woodlake to monitor mosquito abundance and WNV activity.   

It is recommended that residents take precautions to avoid being bitten, thereby reducing the opportunity for exposure to West Nile Virus. California Department of Public Health and Tulare County HHSA recommend that individuals protect against mosquito bites and WNV by practicing the “Three Ds”:

  • DEET – Use repellent containing DEET, picaradin, oil of lemon eucalyptus or IR3535 according to label instructions. Repellents keep mosquitoes from biting you. Insect repellents are safe for pregnant women. Avoid using repellants on children under two months of age.
     
  • DAWN AND DUSK – Mosquitoes that can transmit WNV usually bite in the early morning and evening so wear proper clothing that covers legs and arms 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 flower pots, 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.

Symptoms of WNV include fever, headache, body aches, skin rash, and swollen lymph nodes. Many cases are mild and go unreported. See your primary care physician or family clinic if you have these symptoms.

Help track the West Nile Virus by reporting all dead birds and squirrels. Call 1-877-968-2473 to report a dead bird or squirrel, or you can submit an online report to the California West Nile website at http://westnile.ca.gov/.
