West Nile Virus Infected Mosquitoes Found In The Coachella Valley

CREATED Jun. 8, 2012

INDIO - The Coachella Valley Mosquito and Vector Control District received confirmation from the Center for Vectorborne Diseases (UC Davis) of  ten (10) West Nile virus (WNV) positive mosquito samples in the Coachella Valley.

The mosquito samples were collected on June 6th, 2012 from mosquito traps located south of Mecca and along the shore of the Salton Sea, increasing the number of positive mosquito samples to nineteen (19) this year. District staff will intensify mosquito surveillance, larviciding, and public awareness in these areas, in an effort to reduce the number of mosquitoes and interrupt further transmission of disease. 

West Nile virus was first detected in 2003 in the Coachella Valley and since then has caused two human deaths, 16 non-fatal human cases, and the District has detected 398 positive mosquito samples.

West Nile is transmitted to humans and animals by the bite of an infected mosquito that is capable of transmitting the virus. Mosquitoes become infected when they feed on infected birds.

A Vector Control District spokesperson says most individuals who are infected with West Nile virus will not experience any illness. Others will have only mild symptoms, such as fever, headache and body aches. However, young children, the elderly or individuals with lowered immune systems are at greater risk of experiencing more severe symptoms when infected.

West Nile virus causes illness and death every year, however many cases are never tested and confirmed by physicians.

Residents can reduce risk of mosquito-borne diseases by following the 3 D's of West Nile Virus prevention:

1. Dump/Drain - Eliminate standing water because that's where mosquitoes breed

2. Dusk/Dawn - Avoid outdoor activities when mosquitoes most active

3. Defend - Apply insect repellents with EPA-registered active ingredients such as DEET and Picaridin and wear long-sleeve shirts and pants when outdoors. Utilize properly fitted and well maintained screens on windows and doors around your home.

Concerned residents are encouraged to contact the Coachella Valley Mosquito and Vector Control District at 760-342-8287 or 1- 888-343-9399 to report mosquito problems, request mosquitofish, and report neglected pools or standing water breeding mosquitoes.
