Department officials say this is the first human case reported this year. By August last year there were three confirmed cases. They say two mosquito samples have also tested positive with the virus.
Susan Morris of the Wichita County Public Health Department said, "The most common mosquito is Wichita Falls is the mosquito that we call the Southern House Mosquito. And at this time of year you are going to find that type of mosquito in your house. You will see it on your walls you will see it in the bathrooms, it will come up through your drains."
Morris says you should keep a fly swatter to kill the mosquitoes in your home. The Environment Health Division is also reducing the risk of illness by mosquito control measures, like spraying for adult mosquitoes, treating standing water to eliminate breeding and testing mosquitoes for the virus.
Health officials say you can also do your part to reduce your risk and it's as easy as following the four "Ds."
They say stay indoors during Dawn and Dusk because that's when mosquitoes are most active.
Dress in long sleeves and pants when you are outside.
Use repellent that includes Deet in the ingredients.
Drain standing water in your yard and neighborhood to avoid mosquitoes breeding.
