WEST NILE VIRUS INFORMATION ACROSS NORTH TEXAS
DALLAS COUNTY - Dallas County Health and Human Services (DCHHS) has confirmed the county’s thirteenth West Nile Virus related death in Dallas County.
DCHHS has been notified that a patient who lived in zip code 75089 was diagnosed with West Nile Neuroinvasive Disease and died.
For medical confidentiality and personal privacy reasons, DCHHS does not provide additional identifying information.
DALLAS COUNTY CITIES OPTING OUT OF AERIAL: Lancaster, Sachse, Glenn Heights, Hutchins, Cedar Hill, Balch Springs, Irving, Combine, Desoto, Cockrell Hill
COLLIN COUNTY- As of Aug. 22, 2012, the Collin County Health Department (Collin County Health Care Services) reports 40 confirmed West Nile Virus cases in Collin County, and one related death.
CORINTH- City of Corinth has opted out of the aerial mosquito spraying. However, Lake Dallas, Hickory Creek, and Shady Shores will be participating. Spraying will occur Thursday and Friday night, weather permitting. Therefore, during this time planes will be visible spraying the participating cities.
DENTON COUNTY- The Denton County Health Department (DCHD) has confirmed its second West Nile virus-associated death for 2012. The patient was in her 80’s, had underlying health conditions, and resided in the city of Carrollton. For patient confidentiality, no further information will be released.
ELLIS COUNTY- The West Nile Virus was discussed during the August 27, 2012 Commissioners’ Court meeting. Fire Marshal/Emergency Manager Joe Stewart updated the Court on the County’s efforts to coordinate with cities and towns in Ellis County to fight the spread of mosquitoes that may carry the virus.
The County is utilizing its employees who work in rural areas, such as the road and bridge crews and Department of Development inspectors, to treat any standing water they come across. Stewart said that he “just received a shipment of larvicide from the State that is much more potent than what is available on a retail basis. This larvicide will last up to 150 days, and will carry us through the end of the season.”
Concern has been raised that Ellis County is not spraying aerially like Dallas County. “There are good reasons why we are not spraying,” Stewart explained. “The number one reason is that the State prohibits aerial spraying over agricultural areas, which is a majority of Ellis County.” Dallas County, on the other hand, is mostly urban, and contains highly dense population areas. “Those are the type of areas that aerial spraying is designed for,” Stewart added.
Stewart is also utilizing the County’s mapping capabilities and is keeping track of areas that have been sprayed by cities or treated by the County. He should have a map to release to the public with this information in the near future.
TARRANT COUNTY- Tarrant County Public Health today reports a fifth death associated with West Nile virus (WNV). The death involved a Hurst resident in his 80s, with underlying medical conditions.
ADDISON - Weather permitting, aerial spraying is expected to begin tonight, Friday, August 17, in Addison, Farmers Branch, and Carrollton to control mosquitoes and help prevent the spread of West Nile virus Aerial spraying is planned from 8:30pm until 2:00am.
Planes will fly at approximately 300 feet. You may see planes flying this low at other times…these are practice passes for the pilot.
The aerial spray product poses no health threat and is from the same family of product used by Addison for ground spraying mitigation—it is approved by the EPA and CDC for use.
The aerial spraying times were chosen because that is the peak flying time of the targeted female mosquito.
Aerial spraying is considered to be an effective and safe way to kill adult mosquitoes in large, densely populated areas.
ALLEN- Collin County Health Care Services has reported a fourth confirmed case of the West Nile Virus in Allen residents. An additional case has been reported by the agency in an unincorporated area outside Allen city limits with an Allen mailing address.
The Arlington ISD is monitoring the West Nile Virus situation closely and is constant communication with our city officials regarding this matter. We will send a letter home with parents the first day of school addressing concerns over the West Nile Virus. As part of that letter the AISD encourages parents to consider the following:
- Application of a mosquito repellant that contains DEET, Picardie or oil of lemon eucalyptus before children leave home in the morning. Mosquitoes are most active in the morning and evening hours. Children are at risk while outside in the morning walking to school, waiting for the bus, or traveling from their ride into the building. Most repellents are good for several hours, with many labeled as effective for 8-10 hours after application.
- Students DO NOT need to carry mosquito repellant to school. The risk of misuse or exposure of allergic students far outweighs any potential benefit.
- Parents should consider reapplying a mosquito repellant if students are participating in after school activities and will be outside in the evening.
- The AISD will have DEET containing mosquito repellants for students who remain after school to participate in outdoor school sponsored activities. In this case parents are responsible for advising their children over the use of the DEET product. Parents should consider any allergies that their student may have to a DEET product. Students who choose to use the DEET product will obtain the product from the AISD staff for self-application outdoors only.
The district has posted information on ways to prevent West Nile on the district's website and social media outlets. We have also given this information to our coaches and band directors to share with their students who are participating in outdoor practices. Facilities Services has directed custodial staff to actively monitor and report any standing pools of water so they may be addressed. Custodians at each location are to do an initial site survey for standing water and perform additional surveys after each rain event.
BURLESON- The City of Burleson is not spraying for mosquitoes. If that decision is made, we will notify our residents and all media at least 48 hours in advance.
Targeted ground-based spraying for mosquitoes is scheduled to start tonight, Aug. 29, at 9 p.m. Since the public was alerted on Aug. 27 that the City would be spraying Aug. 29-31, 9 p.m.-5 a.m., City personnel have received questions concerning the product that will be sprayed and whether or not it can harm pets.
The pesticide being used for ground spraying is Environ 30-30. The active ingredient in this product is Permethrin. Permethrin is a man-made chemical that acts like the natural insecticide in the chrysanthemum flower. Because the product is applied at very low concentrations, it is not likely to harm the health of adults, children, or pets. The actual amount of dilute insecticide that lands on a typical one-quarter acre lot is less than one-third of a teaspoon. Less than 5/100ths of a teaspoon (2 or 3 medicine dropper drops) of active ingredient lands on a typical home site as microscopic droplets.
Permethrin has been registered by the Environmental Protection Agency (EPA) since 1977 and is commonly used in mosquito control programs. It is also used in household insect foggers and sprays, tick and flea sprays for yards, flea dips and sprays for cats and dogs, termite treatments, agriculture and livestock products, and on clothing.
Permethrin is sprayed using ultra-low volume sprayers mounted on trucks. This method of spraying targets adult flying mosquitoes. Permethrin is generally toxic to mosquitoes only when they come into contact with the spray droplets. Spraying is performed 9 p.m. until 5 a.m. After hitting the ground, the pesticide decomposes in sunlight and in contact with moisture in less than 24 hours.
Although the product being sprayed is not likely to harm the health of pets, pet owners are advised to remove pets, along with their food and water bowls, from outdoor areas during spraying if spraying occurs in their neighborhood.
For more information on Permethrin, please refer to the National Pesticide Information Center General Fact Sheet on Permethrin at http://npic.orst.edu/factsheets/PermGen.pdf. For more information about the planned spraying for mosquitoes to combat West Nile Virus, go to the Aug. 27 City of Burleson news release at http://tinyurl.com/9lwb2xu. The map of the affected neighborhoods may take a few seconds to load. If you can not get the map to load, a large map is available for viewing 24/7 in the foyer at Burleson City Hall, 141. W. Renfro St.
We did not spray last night and spraying will not take place tonight and Saturday. Please correct this erroneous information on your newscasts and web sites. If you have any questions, please contact me. Thank you for all of your assistance.

DUNCANVILLE - Will now take part in the aerial spraying of Duet done by Clark.
FARMERS BRANCH - Planes spraying mosquito-targeting insecticide made two passes over Farmers Branch Sunday and Monday nights which completes Dallas County's current schedule until after further testing.
Dallas County officials said mosquito traps will be examined to determine the relative effectiveness of the aerial spraying program. Depending on those results, additional aerial treatments could be advised. But, until further notice, the aerial spraying program has concluded.
However, county officials warned recent rain has created even more opportunities for standing water where mosquitoes can breed and urged residents to remain vigilant to containers that may harbor standing water including old tires, flower pot pans, swimming pools, clogged roof gutters, bird baths, french drain systems and other items. Late Monday, a fifth Farmers Branch resident was confirmed to be suffering from symptoms associated with West Nile virus.
The City of Farmers Branch has set up a special message on West Nile Virus and any future aerial spraying on AM radio at 1670 and by recorded message at 972.919.9868. Any updated information will be posted to those two locations as well as the City's website at farmersbranch.info, as soon as it becomes available.
FERRIS - Will now take part in the aerial spraying of Duet done by Clark.

While the pesticide is approved by the EPA, residents who are concerned about exposure are advised to take the following precautions:
- Avoid being outside, close windows and consider keeping pets inside while spraying occurs.
- If skin or clothes are exposed, wash them with soap and water.
- Rinse homegrown fruits and vegetables with water as a general precautionary measure.
- Cover small ornamental fish ponds.
- Because the chemical breaks down quickly in sunlight and water, no special precautions are suggested for outdoor swimming areas.
In addition to ground level spraying, parks, trails, creeks, drainage channels and other green spaces continue to be inspected regularly and treated with mosquito larvicide as needed.
PLANO- The Plano Environmental Health Department has received notification from the Collin County Health Department of two additional human cases of West Nile Virus within zip codes 75023 and 75024.
This brings the total number of cases reported in Plano to 23 for 2012.
Plano’s Environmental Health Department continues to utilize the City’s Integrated Pest Management program by providing habitat reduction strategies to the public, monitoring for mosquito activity and applying mosquito larvicide and spray abatement measures.
At this time, the City’s Mosquito Management Program does not include plans for aerial spraying similar to that conducted in Dallas County and scheduled for Denton County.
RICHARDSON - Mayor Bob Townsend has sent a letter formally requesting Dallas County Judge Clay Jenkins include Richardson in Dallas County’s aerial mosquito control program. The request comes at the recommendation of federal, state and local health officials who have identified an immediate public health threat in Dallas County due to the spread of the West Nile virus.
ROWLETT - An Emergency City Council Meeting took place last night, Monday, August 20, to finalize whether or not the City of Rowlett would participate in Dallas County’s Aerial Mosquito Spraying program. After conducting their own research and carefully considering all of the input offered by citizens, whether in person or via email and social media, the Rowlett City Council voted to opt in.
According to Dallas County officials, the aerial spraying for Rowlett will occur Wednesday, August 22 and Thursday, August 23 between the overnight hours of 9:00 P.M. and 1:00 A.M., weather permitting.

The Emergency Meeting agenda is posted on the Sachse City Website at: http://sachse.legistar.com/Calendar.aspx.
SEAGOVILLE - Will now take part in the aerial spraying of Duet done by Clark.
SOUTHLAKE- Currently, the City is actively engaged in a campaign to deploy larvicide in areas of standing water on public property since the first area tested positive for mosquitoes carrying WNV in late June. Larvicide tackles the problem by interrupting the mosquito life cycle, thus preventing the development of adult mosquitoes. While this prevents mosquito development on public property, it does not address the large number of mosquito breeding grounds on private property.
SUNNYVALE - Will now take part in the aerial spraying of Duet done by Clark.
UNIVERSITY PARK- City staff will resume fogging by truck beginning Wednesday, August 22. The resumption of this effort follows the announcement from Dallas County Health and Human Services on Tuesday, August 21 that a University Park resident died of West Nile Neuroinvasive Disease, and the announcement by the County on Wednesday, August 22 of the hospitalization of another University Park resident for West Nile Neuroinvasive Disease. Truck fogging will take place from 11 p.m. to 5 a.m. only.
The schedule now through the end of August is on the City’s website homepage.
