DALLAS -- Dallas County reported its 50th case of West Nile virus for the 2016 season on Thursday.

The infected person lives in the 75149 ZIP code in Mesquite and contracted West Nile neoinvasive disease, the more serious form of the virus. No other identifying information was released.

As long as mosquitoes persist this season, the risk of West Nile exists. The best thing to do to prevent infection is to protect yourself.

Dallas County Health and Human Services recommend the “4 D’s” to reduce exposure to mosquitoes:

DEET -- Use insect repellents that contain EPA approved repellents
Dress -- Wear long and loose-fitting clothing outside
Drain -- Drain or treat standing water around your home or workplace
Dusk and Dawn -- Limit time spent outside during these peak mosquito times

Two people have died from West nile virus so far this year in Dallas County. The first human case of the virus this year in the county was confirmed in early July.
