West Nile Found Mostly in Sherman Oaks and Encino


Summer is waning but the mosquitos are still thriving and Sherman Oaks, Encino and Van Nuys are still finding samples testing positive for the West Nile Virus.

The Greater Los Angeles Vector Control District (GLACVCD) continues to remind residents that the threat of West Nile virus (WNV) is still widespread in Los Angeles County.

This week, GLACVCD confirmed WNV-positive test results for 22 mosquito samples and three sentinel chickens that tested positive for West Nile virus. 

"As long as we have warm weather and standing water, mosquitoes will be active," said Levy Sun, GLACVCD public information officer. 

"Regardless of the season, mosquitoes will have the potential to transmit West Nile virus in our communities," he said.

Please refer to the charts below for a breakdown of the latest West Nile virus activity.

So far this year, the District has reported a total of 334 positive mosquito samples and 63 dead birds. In addition, a total of 26 surveillance chickens have shown antibodies for West Nile virus. Sentinel chickens are one of the District's surveillance tools used to detect West Nile virus transmission in the area.

The District recommends taking the following steps to protect against mosquito bites:

  1. Dusk / Dawn - Avoid outdoor activities when mosquitoes are most active between dusk and dawn.
  2. Defend - If you are outside where mosquitoes are active, use insect repellent to avoid mosquito bites and to reduce the risk of acquiring any mosquito-borne diseases. Insect repellent that are most effective contains EPA-registered active ingredients such as DEET, Picaridin, IR3535, and oil of lemon eucalyptus.
  3. Dump / Drain - Eliminate standing water on your property. It can take as little as three days for mosquito eggs in a saucer or dirty pool to hatch into biting adults.

The public is encouraged to report dead birds to help with West Nile virus surveillance and control efforts because birds play an important role in maintaining and spreading the virus.
