Orange County adds faster testing for mosquito-borne illnesses

New laboratory technology could provide same-day results and accelerate mosquito-control responses

Posted

In Summary:

Orange County Mosquito Control can now test mosquito samples in-house for several mosquito-borne illnesses. The molecular testing technology searches for the genetic material of viruses including West Nile, dengue, Zika, and chikungunya. County officials said faster results will allow crews to respond more quickly when a virus is detected.

The new molecular testing capability uses PCR technology to detect the genetic material of specific viruses in mosquito samples. The highly sensitive method allows laboratory staff to determine whether mosquitoes collected through the Mosquito Control surveillance program are carrying certain mosquito-borne illnesses.

The staff can now test mosquitoes for:

  • West Nile Virus
  • Eastern Equine Encephalitis Virus
  • St. Louis Encephalitis Virus
  • Dengue Virus – all four types
  • Zika Virus
  • Chikungunya Virus

“This new technology’s biggest advantage is saving time,” said Steve Harrison, manager for Orange County Mosquito Control. “Previously, we had to send samples outside of our laboratory. Now, we can potentially have results the same day, which will lead to faster responses and mitigation efforts.”

Orange County Government strives to serve its residents and guests with integrity, honesty, fairness, and professionalism. Located in Central Florida, Orange County includes 13 municipalities and is home to world-famous theme parks, one of the nation’s largest convention centers and a thriving life science research park. Seven elected members make up the Board of County Commissioners, including the Mayor, who is elected countywide. For more information, please visit www.OCFL.net.

Key Points:

  • Orange County Mosquito Control has added PCR testing technology to its laboratory.
  • Samples previously had to be sent to an outside laboratory for testing.
  • Laboratory employees could now receive results on the same day.
  • The county can test for West Nile, Eastern equine encephalitis, St. Louis encephalitis, dengue, Zika, and chikungunya viruses.
  • Faster detection could improve mosquito mitigation efforts while reducing costs and waiting times.
