16 More Mosquitoes Test Positive for West Nile Virus

CREATED Sep. 16, 2011

INDIO- The Coachella Valley Mosquito and Vector Control District received confirmation from the Center for Vectorborne Diseases  of 16 new West Nile virus positive mosquito samples in the Coachella Valley.

The mosquito samples were taken from traps located southeast/ southwest of Mecca. District staff will continue its intensified mosquito surveillance, larviciding, and public awareness in these areas, in an effort to reduce the number of adult mosquitoes.

The District is currently still undergoing ground ultra low volume application and barrier treatments in this area to reduce the adult mosquito population.

This year there have been 32 confirmed WNv positive mosquito samples and seven sentinel chickens positive for WNv in the Coachella Valley. In 2010, the District had 66 confirmed WNv positive mosquito samples from across the valley, by this point in the season.

WNv was first detected in 2003 in the Coachella Valley. In 2004, a resurgence of the virus resulted in seven non-fatal human cases, 75 positive mosquito samples and six dead birds. Since 2005 in the Coachella Valley, WNv has caused three human deaths, 11 non-fatal human cases and the District has detected 394 positive mosquito samples.

WNv is transmitted to humans and animals the bite of an infected mosquito. Not all species of mosquitoes are capable of transmitting the virus. Of those that can transmit the virus only a small percentage are actually infected with the virus. Mosquitoes become infected when they feed on infected birds. Most individuals who are infected with WNv 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. WNv causes illness and death every year, however many cases are never tested and confirmed by physicians.

The District continues its extensive surveillance, prevention, and treatment programs throughout the Coachella Valley and urges residents to help reduce mosquito breeding sources by inspecting their backyards and neighborhoods for standing water sources at least once a week.

Individuals can reduce their risk of mosquito-borne diseases by taking these precautions:

-Avoid outdoor activity at dusk and dawn
-When outdoors, wear long pants, long-sleeved shirts and other protective clothing
-Apply insect repellent according to label instructions
-Make sure that doors and windows have tight fitting screens
-Repair or replace screens that have tears or holes
-Eliminate all sources of standing water on your property that can support mosquito breeding
-Report swimming pools and ornamental ponds that are not being maintained
-Keep ornamental ponds and neglected pools free of excess vegetation

Contact the District for free mosquitofish to place in your ornamental pools, neglected pools or any other container with standing water that can potentially breed mosquitoes

Contact the District if there is a significant mosquito problem where you live or work.
