West Nile Virus Alert for San Fernando Valley

My name is Helen Kuan and I am an acting public information officer for the Greater Los Angeles County Vector Control District (GLACVCD). I would like inform you that GLACVCD has confirmed the first mosquito sample to test positive for West Nile virus (WNV) in the Porter Ranch this year. The mosquitoes were collected in a trap in the city on August 10th. District staff will place posters around the trap locations to advise residents to take precautions when mosquitoes are present. In addition, I have attached graphics that you may use to post on social media and other communication channels. For more information about WNV activity in the District’s service area, please visit: https://www.glamosquito.org/west-nile-virus-activity-2023.

WNV is transmitted to people and animals through the bite of an infected mosquito. There is no cure for WNV. One in five persons infected with the virus will exhibit symptoms. Symptoms can include fever, headache, body aches, nausea, or a skin rash. There is no human vaccine for WNV, and severe cases can lead to paralysis or even death.

Mosquito Prevention and Protection

Mosquito control is a shared responsibility and residents must take an active role in reducing the threat of WNV in their neighborhoods by taking the following steps:

  • Eliminate standing water in clogged rain gutters, rain barrels, discarded tires, buckets, watering troughs or anything that holds water for over a week.
  • Ensure that swimming pools, spas, and ponds are properly maintained.
  • Change the water in pet dishes, birdbaths and other small containers weekly.
  • Wear insect repellent when outdoors where mosquitoes may be present.
  • Report neglected (green) swimming pools in your neighborhood to GLACVCD.

Thank you and please reach out if you have any questions,
