RICHARDSON City workers in Richardson postponed plans to begin spraying for mosquitoes on Sunday evening in an effort to halt West Nile virus before it starts.
It was too windy for the spray trucks to operate effectively.
Earlier this week, mosquitoes trapped in Richardson tested positive for the virus.
This is the earliest date for spraying in Dallas County since health authorities began tracking West Nile in 2002.
- West from Central Expressway to Coit Road between Arapaho Road and Campbell Road.
- South from Lookout Drive to Apollo Road, bounded by Plano Road on the west and Jupiter Road on the east.
- East from President George Bush Turnpike to Breckinridge Park, bounded by the city limit on the north and south.
West Nile virus is spread by infected mosquitoes. The Centers for Disease Control say more than 30,000 people in the U.S. have been sickened by the illness since 1999.
Last year, the CDC reported 5,387 cases in 48 states; 243 patients died.
One-third of all West Nile cases last year 1,739 were from Texas. Dallas County counted 371 cases, by far the most in the state.
