San Diego County officials have confirmed the first detection of West Nile virus (WNV) in the region this year after two dead crows in Lemon Grove tested positive for the virus. The discovery came during routine monitoring and has triggered a renewed warning to protect against mosquito-borne diseases.

While no human cases have been reported yet, warmer temperatures are increasing mosquito activity across Southern California.

Follow the Three-Step Rule: Prevent, Protect, Report

1. Prevent mosquito breeding:
✔️ Dump standing water from containers (buckets, toys, plant saucers, tires)
✔️ Clean birdbaths and pet bowls weekly
✔️ Use mosquitofish in ponds, fountains, or unused pools

2. Protect against bites:
✔️ Wear long sleeves and pants outdoors
✔️ Use EPA-registered insect repellents (DEET, picaridin, oil of lemon eucalyptus, etc.)
✔️ Keep door and window screens in good condition

3. Report:
✔️ Report dead birds (especially crows, jays, hawks, owls)
✔️ Report mosquito activity in your area

Stay alert, especially in warm months when Culex mosquitoes, the primary WNV carriers, are most active. For resources or to report mosquito concerns, visit comptoncreekmad.org.
