dallasWest Nile Virus (WNV) is a disease that is spread by the bite of an infected mosquito. Mosquitoes can become infected when they feed on the blood from infected birds. The infected mosquitoes can then transmit WNV to humans and animals. Severe WNV infections can cause neurologic complications such as encephalitis. Milder symptoms include fever, headache and muscle aches. There is no vaccine or specific treatment for WNV.

Dallas County has also reported 4 cases of another mosquito borne disease, chikungunya, this year to date. All four cases are associated to overseas travel.

As of Aug. 19, Texas has reported 27 WNV cases and 19 chikungunya.
