Also on Wednesday, DCHHS announced that ground mosquito insecticide spraying will be done in the City of Irving.

If weather permits, spraying will be done on both August 29 and August 30, around 10 p.m.

The spraying will be centered on four cluster areas, mainly in the far south and west portions of the city, where positive West Nile virus mosquito pools have been found.

While everyone is at risk of being affected by West Nile Virus, the very young and people age 50 and older are at a higher risk of developing a severe infection.

While human West Nile infection is rare, as a precaution against mosquito bites and potential infection North Texans should:

• Stay indoors at dawn, dusk and in the early evening
• Wear long-sleeved shirts and long pants when outdoors
• Spray clothing with repellents containing permethrin or DEET
