A Fort Worth woman in her 40’s has developed Tarrant County’s first case of West Nile virus this season.   It’s also the first case reported in North Texas.

Tarrant County Public Health says she has the milder form, not the neuroinvasive form that more often leads to long-term illness, paralysis or death.

Governor Perry has signed Senate Bill 186, giving health officials another tool to fight West Nile.

The bill sponsored by Rep. Helen Giddings and Sen. John Carona, both of Dallas, gives authorities access to stagnant water on abandoned properties and swimming pools.  

Dallas County health officials say that last year they had numerous complaints about standing water on uninhabited properties that was breeding mosquitoes.

Mosquitoes carry the West Nile virus that can be fatal or cause severe neurological damage.

After finding mosquitoes carrying West Nile Virus earlier than usual in at least two cities, Dallas County officials have begun urging outdoor use of mosquito repellent containing DEET.

Mosquitoes with West Nile Virus have arrived earlier than ever before in North Texas. Last week, several traps in Richardson had mosquitoes that tested positive for the virus – last year West Nile didn’t appear until May.

Dallas County is tripling the number of mosquito-spraying trucks available for this West Nile Virus season. And, the County Judge is backing a new state law that attacks abandoned swimming pools – fertile mosquito breeding grounds.

Fighting West Nile

Feb 15, 2013

In 2012, Texas became the national epicenter for cases of human infection from the West Nile virus, and nowhere did the mosquito-borne disease claim more victims than in Dallas County. 

Statewide more than 80 Texans died and nearly 2,000 became severely ill.  Dallas Mayor Mike Rawlings  declared a state of emergency and authorized the city’s first aerial spraying of pesticides since 1966.

The mosquito population in parts of Dallas and Denton counties actually increased after last summer’s aerial pesticide spraying.  But, the Centers for Disease Control found the number of human cases of the mosquito-borne illness went down.
