West Nile reported in Denton County

04:48 PM CDT on Monday, June 2, 2008

By Dan X. McGraw/Staff Writer

It?s West Nile season, already.

On Monday, the Denton County Health Department reported the first case of West Nile virus had been confirmed in Flower Mound, said Betsy Haggard, the spokeswoman, said. It was the second case in the state.

The person was diagnosed with West Nile fever, the less serious of the two forms of the virus, and the resident has already been treated. Flower Mound will begin spraying Thursday night to reduce the chances of the virus.

No other cities have planned spraying, Haggard said.


?Normally, we see cases starting in July,? she said. ?We don?t normally seem them on June 1.?

The health department?s chief epidemiologist Dr. Jessica Guillon said the early case doesn?t necessarily indicate an unusually heavy mosquito season, and if it did, less than 1 percent of mosquitoes carry the virus.

The mosquito-borne virus develops into either West Nile fever or neuroinvasive disease, but four out of five people infected develop no symptoms at all, Haggard said.

West Nile fever can last as short as a few days or as long as a few weeks with symptoms ranging from fever, headache and tiredness to body aches. Some people report skin rashes on their chest, Haggard said.

Less than 1 percent of those infected develop neuroinvasive disease. The symptoms include headaches, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis.

People over the age of 50 and those with compromised immune systems are at risk for getting severely ill with West Nile.

Spraying

Flower Mound will conduct spraying operations in the areas generally located south of Justin Road to College Parkway and east from Long Prairie Road to Timber Creek Road from 10 p.m. on Thursday, June 5 through 4 a.m. on Friday, June 6.

How to avoid getting sick

Residents can take precautions to reduce their chances of getting sick from the mosquito-borne West Nile virus by remembering the four D?s: drain, dress, DEET and dusk/dawn. Residents should:

Drain standing water around their homes to reduce mosquito hatching grounds.

Dress in pants and long sleeves when outside in mosquito-infested areas, but avoid becoming too hot.

Apply an insect repellent that contains DEET (N,N-diethyl-m-toluamide) to exposed skin and to clothing when outdoors.

Stay indoors at dusk and dawn, when mosquitoes are most active.

Harris County confirms first human case of West Nile

Monday, June 16, 2008

Kathy Parks

Light rain this summer has enticed mosquitoes into neighborhoods where people are watering lawns. The first Culex mosquitoes to test positive for West Nile Virus were trapped in the 77373 ZIP code in Spring.

The first human case of the virus was confirmed on May 16 in a Huffman man living in ZIP code 77336. A trap had been placed at the intersection Beckman Drive at Fantasia Drive.

Last week, trapped mosquitoes tested positive at the intersection of Baton Pass at Relay Road in the Walden subdivision in Atascocita.
No dead birds have been found to date.

?It?s important that people don?t sweep grass clippings from their yard into the sewers,? said Sandy Kachur, spokesperson for Harris County Public Health and Environmental services.

?The mosquitoes are looking for still pools of water and vegetation. Unclean storm sewers can become a ?Club Med? for mosquitoes.?

Kachur said that trapped mosquitoes are grouped in sets of 50, then ground up and tested. One infected mosquito will result in a positive test. A positive test activates sprays in the area. Ideally, an area that tests positive is sprayed at night three times a week. Adjacent areas are sprayed once a week. The county will then continue to check the traps in the area monthly.

Kachur said that this not an unusual mosquito season and that people should always take precautions.

Precautions include: wearing long pants and long-sleeve shirts when outdoors, particularly at dawn and dusk; routinely wearing insect repellents; replacing worn screens; and emptying and refilling pet water bowls at least twice per week.

?If a person experiences flu-like symptoms and he knows he has been exposed to mosquitoes, he should ask his doctor to test him for West Nile Virus,? said Kachur.
