First Indication of West Nile virus Activity in Orange County for 2012
Garden Grove, CA. The Orange County Vector Control District (OCVCD) has confirmed the first mosquito
pool to test positive for West Nile virus in 2012. The mosquitoes were collected from Modjeska Park in
Anaheim on June 19, 2012. OCVCD routinely tests groups of adult female mosquitoes (mosquito pools) and
dead birds for the presence of West Nile virus.
“These findings should serve as a reminder that West Nile virus is an endemic virus in Orange County that
continues to threaten public health. Residents are encouraged to take steps to reduce their exposure to mosquito
bites during Fourth of July weekend celebrations.” stated Robert Cummings, Director of Scientific Technical
Services. “Although the positive mosquitoes were collected in Anaheim, the public should assume that the virus
is now active throughout the county.” said Cummings.
While conducting mosquito surveillance and collecting dead birds is a good way to track the virus in the
County, finding mosquito-breeding sources is much more important. OCVCD urges the public to conduct
routine property inspections for mosquito-breeding sources. Look for any standing water around the house or
neighborhood and either remove the water source or contact OCVCD to remove the potential mosquito-breeding
source. Remember, mosquitoes can complete their life cycle in just one week in a water source as small as a
bottle cap. If you find a dead bird, call OCVCD as soon as possible. A District representative will collect all
viable birds and submit them for testing.
Orange County Vector Control District makes following recommendations to avoid being bitten by mosquitoes:
Eliminate any standing water around your house.
Make sure all window and door screens on your house are in good repair.
Wear a repellent containing DEET®, Picaridin, Oil of Lemon Eucalyptus, or IR 3535.
Contact the Orange County Vector Control District to report dead birds or neglected pools.
