The first human case of West Nile Virus this year in Stanislaus County has been reported.

Public Health received confirmation of a 52-year-old female diagnosed with the West Nile Virus. As of Aug. 11, 2016, there have been 10 human cases confirmed in California, including the latest one in Stanislaus County.

Although most people (70 to 80 percent) who become infected with West Nile do not develop any symptoms, Stanislaus County residents should remain vigilant and are encouraged to continue their efforts to prevent mosquito bites and WNV.

Steps that can be taken include eliminating sources of standing water where mosquitoes lay their eggs; 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. Apply insect repellant containing the active ingredient DEET when outdoors, according to label instructions. In addition to DEET-based products, the Centers for Disease Control also recommend insect repellants containing oil of lemon eucalyptus and Picaridin.

Both East Side and Turlock Mosquito Abatement Districts have been busy locating mosquito breeding sources and treating them as necessary. One source can be neglected swimming pools which can lead to West Nile Virus carrying mosquitoes. The Districts have conducted aerial surveillance photography for neglected swimming pools. The Districts also provide mosquito fish, free of charge, to put in ornamental ponds and other mosquito breeding locations.

According to officials, reporting and testing of dead birds is an important step in preventing West Nile Virus. A confirmed case of the virus in dead birds or mosquito samples helps to identify areas that need treatment to reduce mosquito activity. To report a dead bird, call the California State hotline at 1-877-WNV-BIRD or report it online at Birds of particular interest to the State are crows, ravens, magpies, jays and raptors, either hawk or eagle.

To report mosquito-breeding problem areas, Stanislaus County residents should contact one of the two mosquito abatement districts that serve the county. For Stanislaus County addresses north of the Tuolumne River, residents should call the Eastside Mosquito Abatement District at 2009-522-4098 and all others should contact the Turlock Mosquito Abatement District at 209-634-1234.
