A dead bird found in the 95336 Manteca ZIP code — the area to the north of the Union Pacific Railroad tracks that go through the center of the city — has been confirmed to have been killed by the West Nile virus.

San Joaquin County Mosquito and Vector Control District’s mosquito-borne disease surveillance program confirmed West Nile virus (WNV) positive mosquitoes in one mosquito sample in zip code 95206, and in two mosquito samples in 95219. Both zip codes are in the Delta area.

That is in addition to the dead bird was found WNV positive in Manteca.

These are the first positive mosquitoes and bird found in San Joaquin County this year.

“It is not surprising since neighboring counties have detected WNV activity in the recent weeks as well,” said Ed Lucchesi, Manager of the district.

In response to the detection of WNV, the District will expand surveillance and control of local mosquito populations on all private and public lands within San Joaquin County.

Mosquito control activities include: making recommendations to property owners on methods to reduce mosquito breeding conditions; educating the public on mosquito prevention techniques, including the use of repellents; introducing mosquitofish to ponds, ditches, and other aquatic sites; and spraying areas where mosquitoes are found.

With the upcoming Fourth of July holiday, many of us will be enjoying outdoor activities. It is important that people protect themselves from mosquito bites. Residents and visitors of San Joaquin County can reduce their risk of WNV and other mosquito-transmitted diseases by taking these precautions:

Eliminate all sources of standing water on your property that can support mosquito breeding.

Apply insect repellent containing the active ingredient DEET or Picaridin when outdoors, according to label instructions.

Avoid spending time outside when mosquitoes are most active, at dawn and dusk, and especially for the first two hours after sunset.

When outdoors, wear long pants, long-sleeved shirts and other protective clothing.

Exclude mosquitoes from your home with tight fitting screens on doors and windows.

Contact your veterinarian for information on vaccinating equine against WNV.
