The first human case of West Nile Virus in Dallas for this summer has been determined, the Dallas County Health & Human Services Director Zachary Thompson confirmed on Tuesday.

An unidentified patient in ZIP Code 75217 southeast Dallas/ Pleasant Grove was diagnosed with West Nile Fever, which is a milder form of the virus. Authorities did not disclose any additional identifying information on the affected individual, wfaa.com reported.

The infected individual was reportedly not hospitalized since what he acquired was a less-serious form of WNV and not the more-severe neuro-invasive disease, Dallas officials said.

"The City's protocol is to conduct targeted ground spraying in areas where WNV has been confirmed in mosquitoes, and in areas where trapping has indicated significant increases in the number of mosquitoes that have the potential to carry WNV," City of Dallas spokesperson Crystal Woods said in a news release. "Existing traps near the human case have not tested positive for WNV. The City will expand surveillance and place an additional trap near the location to gain information on mosquito activity."

Although the victim lives in ZIP Code 75217, mosquito traps set in the area haven't tested positive for WNV, CBS DFW has learned. This caused city officials to believe that the infected man was probably bitten somewhere else.

And since no mosquito traps tested positive for West Nile Virus, the city will not be spraying in the area.

Transmitted by mosquitoes, West Nile Virus affects humans, birds, horses and other animals, according to kvewtv.com.

Most infected people are asymptomatic, but those experiencing fever, headache, fatigue, joint muscles and nausea are adviced to immediately see a doctor.

No vaccine or treatment is currently available for West Nile Virus. Health officials however, are urging residents to avoid being bitten by mosquitoes at all costs.

To reduce the risk of West Nile Virus infection, residents are adviced to: drain all standing water in and around the home or workplace; wear loose, long and light-colored clothing; limit outdoor activities when mosquitoes are most active (dusk and dawn) and use insect repellents that contain DEET.
