A sample of mosquitoes collected from traps placed in Golden Hills Wilderness Park in La Verne on August 12, was tested and found positive for the West Nile Virus, according to the San Gabriel Valley Mosquito and Vector Control District.

Vector control officials have already intensified surveillance and control efforts in the foothill communities to prepare for the seasonal emergence of this virus.

The best precaution against West Nile is to prevent mosquito bites.

Mosquitoes pick up the virus from infected birds and spread it to other birds and humans when they bite again.

Throughout the summer, basic protective measures should be followed:

Avoid overwatering and prevent litter, leaves and debris from entering the gutters and streets.

Check properties weekly and remove all sources of standing water.

Report green, inoperable pools or other sources of standing water to the district. Wear effective repellents and long sleeves if outdoors when mosquitoes are present (between dawn and dusk.) Ensure doors and windows are properly screened.

Vector Control encourages the public to help identify West Nile “hot spots” by reporting dead birds to their hotline at 877-WNV-BIRD (877-968-2473) or online at www.westnile.ca.gov.
