Summer may be winding down, but more and more cities in North Texas are reporting an increase in West Nile virus-positive pools.
Dallas County reported four more on Friday, bringing its total to 102 positive West Nile virus mosquito pools located this season.
Six human cases have been reported in Dallas County as of Friday.
And people in Fort Worth received the following message Friday: "FT WORTH: Number of mosquitoes w/ West Nile Virus continues to rise. Drain standing water in flower pots, pet bowls, toys. Use Insect spray w/ Deet."
