Collin County health officials have alerted the city of Frisco of the first human case of West Nile virus in the city this year. The case was reported in the 75035 ZIP code. The person has recovered from the virus and did not report any travel outside of the United States, according to a news release. Environmental Health Supervisor Julie Stallcup said no ground spraying is scheduled in response to this case because the patient is no longer ill, and the city does not know when or where the person was infected. "However, staff will continue routine checks for stagnant water throughout the city, treating as needed," Stallcup said in a news release. The city of Frisco supports precautionary steps promoted by the Texas Department of State Health Services, which are commonly referred to as “The Four D’s”:

  • drain all standing water;
  • dress in light-colored, long-sleeve clothing when outdoors;
  • deet—use mosquito repellents that contain deet; and
  • dusk or dawn—avoid outdoor activities during these hours when mosquitoes are most active.
Last year the city began increasing the number of sites that were tested for West Nile virus in an effort to better control the mosquito population in Frisco. Municipal Mosquito has worked with the city since 2010 to set up traps and spray the area when positive results called for it. When a positive pool is found, Municipal Mosquito will treat positive standing water pools with larvicide to prevent mosquito eggs, larvae or pupae from developing. As an additional treatment step, Municipal Mosquito will conduct ground-based adult mosquito control, known as fogging and spraying, in the targeted areas by using organic solutions.
