“The confirmation of additional human cases and deaths due to West Nile virus this year is an extremely important reminder to the community of the need to take steps to avoid mosquito bites and to reduce mosquito populations,” said Dr. Philip Huang, Director of DCHHS. “Staying vigilant and practicing the 4Ds are the best ways to avoid exposure to mosquito-borne diseases.”
• DEET: All Day, Every Day: Whenever you’re outside, use insect repellents that contain DEET or other EPA approved repellents and follow instructions.
• Dress: Wear long, loose, and light-colored clothing outside.
• Drain: Drain or treat all standing water in and around your home or workplace where mosquitoes could lay eggs.
• All Day long: Day, Dusk and Dawn - Limit your time outdoors mosquitos are active anytime day or night.
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. For more information, visit www.dallascounty.org/departments/dchhs/westnile.php.
