Mosquitos with West Nile Virus Found in Mountain View

The Santa Clara County Vector Control District will fog potentially affected areas starting at 11 p.m. Thursday night for several hours.

Adult mosquitoes collected in Los Altos, Los Altos Hills and Mountain View tested positive for West Nile virus prompting officials to plan for a ground fogging on Thursday.

Mosquitoes were collected from ZIP code areas 94024 and 94040 and the virus was confirmed on Friday, according to a press release from the Santa Clara County Vector Control District (SCCVCD).

SCCVCD will fog the areas generally bordered by Rosita Avenue, Glen Alto Drive, Arboleda Drive, Cuesta Drive, and Eunice Avenue on the north. Campbell Avenue, La Prenda Road, Quinnhill Road, and Casa Mia Way on the west; Truman Avenue, Malbarough Avenue, Wessex Avenue, Austin Avenue and Grant Road on the east; and 280 Freeway and Saint Joseph Avenue on the south.

"While we're seeing a slow start to the (West Nile) virus season this year, the detection of virus in mosquitoes—in this case one in 75 mosquitoes were infected—represents a direct risk of human infection," said Scott Bourdon, director of the Department of Environmental Health in a statement. "Control of infected adult mosquitoes is an essential component of preventing human cases and other mosquito-borne encephalitis."

Transmitted by mosquito bites, West Nile Virus causes mild to severe flu-like symptoms such as fever, headache, body aches and in severe cases, significant neurological damage or even death. The elderly and those with compromised immune systems are most susceptible.

The fogging will begin at 11 p.m. on Thursday and is planned to last for several hours.

Residents in the effected fogging areas will receive printed information about the fogging, and district staff will be available to answer questions during extended hours from 7:30 a.m. to 7 p.m. on Wednesday and Thursday on a dedicated phone line/voicemail at 800-314-2427.

is this the 1st time this area is being fogged?
mmm August 09, 2012 at 05:22 AM
Why don't they directly contact folks in the area (both the directly affected area and the surrounding area)? Didn't they just do this last year? This seems like a bad idea.
Russ Parman August 09, 2012 at 08:01 PM
This is the first fogging of the season.
Russ Parman August 09, 2012 at 08:02 PM
Yes. We've fogged nearby in Sunnyvale in past seasons.
Russ Parman August 09, 2012 at 08:07 PM
We produced 6,000 flyers to be hand delivered to each residence within the fogging zone. We're getting reports now that a few streets may not have received the flyers. We also issue press releases and website updates, and send email notices out via our Yahoo email fogging notice list.

Thanks Russ for the updates. Quick question: Is one fogging usually enough? Also, can you email me a copy of the flier at claudia.cruz@patch.com? Thanks!
MN August 10, 2012 at 03:35 AM
so then we've been getting drift from those past foggings w/no notification?
MN August 10, 2012 at 07:02 PM
is this exactly what the spraying looked like? did you guys spray at that angle/height? http://www.youtube.com/watch?v=LV-cq4X7Ezk&feature=related INADEQUATE NOTICE! we only happened to hear about this because of this site!
Claudia Cruz (Editor) August 10, 2012 at 07:39 PM
Russ, any update on how the spraying went?
Russ Parman August 10, 2012 at 08:02 PM

Claudia - In most cases, one fogging is enough here, but on occasion we do continue to find virus in post-treatment samples and have to conduct subsequent operations. MN - Almost identical except for two details; we usually only fog for one evening, and we have radar sensors that automatically adjust the output to the speed of the truck, so we're not stuck having to travel at an exact speed. We do however usually go about 15mph.
Russ Parman August 10, 2012 at 08:15 PM
MN - Re the drift question; not likely as the closest one was about a half mile away. We shoot for a 300-foot swath from the truck. BTW if it shows up, I accidentally click on the "flag as inappropriate" link next to your question. It was indeed a GOOD question! l0)
