Dallas, Texas – In a recent public health update, Dallas County Health and Human Services (DCHHS) has announced the detection of the second human instance of West Nile Virus (WNV) infection within Dallas County for the year 2023.
The impacted individual, a woman residing within the boundaries of the 75231 postal code in the City of Dallas, has been medically identified with West Nile Neuroinvasive Disease (WNND). To maintain and uphold stringent principles of privacy and confidentiality, DCHHS is refraining from releasing any additional details pertaining to the patient’s identity.
“Mosquito activity continues in Dallas County, and we are now reporting the second human case of West Nile Virus of the 2023 season. WNV is transmitted to humans by the bite of an infected mosquito, and people should be careful when going out outside to enjoy outdoor activities,” said Dr. Philip Huang, DCHHS Director. “Please follow the 4 Ds to do everything you can to avoid mosquito bites.”
West Nile virus: what should you do to be safe
- DEET: The use of insect repellents containing DEET or other EPA-endorsed compounds is advised, alongside adherence to their prescribed usage instructions.
- DRESS: Adorn long, loose, and light-colored attire during outdoor ventures.
- DRAIN: Undertake measures to drain or treat all instances of stagnant water in and around residences and workplaces, which often serve as breeding grounds for mosquitoes.
- DAWN to DUSK: Curtail outdoor activities during dawn and dusk, the periods when mosquitoes are most active.
The West Nile Virus is a disease predominantly spread by the bite of an infected mosquito. Mosquitoes often become carriers of the virus following the consumption of blood from an infected bird. Consequently, these contaminated mosquitoes can transmit WNV to humans and animals alike. Severe WNV infections can engender neurological complications such as encephalitis, while milder manifestations can cause fever, headache, and muscle aches. Currently, there exists no designated vaccine or specific treatment for WNV.

The first West Nile human case in Dallas in 2023
The first West Nile human case in Dallas this year was identified earlier this month. North Texas sees a few cases of West Nile every year, with three human cases reported by the DCHHS in 2022. The virus is spread through the bite of infected mosquitoes, and can infect both humans and animals.
