We received this notice at city hall today from the County Department of Environmental Health:
On August 28, 2008 the Department of Environmental Health Vector Control
Program trapped adult mosquitoes as part of the routine monitoring of
adult mosquitoes in the Encinitas Creek area. One mosquito sample (17
mosquitoes) from the trap was analyzed by U.C. Davis for the presence of
The results were returned to Vector Control on
September 5, 2008 as being positive for West Nile Virus (WNV). The
location of the mosquito trap is in the Encinitas Creek region near
Village Square Drive. To date there have been 12 West Nile
positive dead birds retrieved from the City of Encinitas.
The WNV positive mosquito sample, as well as the presence of the dead
birds is strong indicators of the presence of WNV in the area. The
Vector Control Program is taking the following actions:
1. Mailing out precautionary letters to the residents of Encinitas in
the potentially infected area.
2. VCT staff will canvass the neighborhood and conduct an aerial search
for un-maintained swimming pools
3. VCT staff will be searching the adjacent creek and storm water
drainage courses this week for evidence of breeding and treat with
larvicide as needed
4. VCT staff has placed more mosquito traps in the area. These will also
be sent to U.C. Davis for testing
5. A press release has been issued regarding the positive mosquito
samples and personal protection information.
We wanted to make you aware of these actions we are taking in your city.
