All Mosquito Traps in Richardson Return Negative West Nile Virus Tests This Week
Posted Date: 8/30/2013 12:30 PM

The Richardson Health Department reported that mosquitoes in each of its 12 traps returned negative results for West Nile virus this week. This follows six consecutive weeks with at least one trap testing positive.

Richardson began its West Nile virus monitoring program in April, which is the earliest it has ever begun testing for signs of the virus, and weekly testing at the 12 locations will continue through October. The Richardson City Council approved increased surveillance this year due to the heightened incidence of West Nile virus cases experienced in the Metroplex in 2012.

So far this year, the rate of reported infections in people has been significantly less, hopefully the result of more proactive mosquito abatement measures enacted this year. (Watch the video below to learn about the Health Department's increased mosquito abatement program.)

Mosquitoes remain active, however, so people are asked to follow the Four D’s to protect themselves from mosquito bites:

  • DRAIN standing water around the home,
  • Use insect repellent containing DEET,
  • Avoid being outdoors at DUSK and DAWN when mosquitoes are most active,
  • And DRESS to protect yourself with long sleeves and pants to reduce skin exposure.
