In 2003, Dallas County had a total of 54 human West Nile cases with 4 deaths. In 2002, the first year the virus was reported in Dallas County, there were 27 human cases with 3 deaths.
DCHHS staff is partnering with the municipalities to distribute public education materials throughout the community. The best way to avoid exposure to West Nile virus and other mosquito-borne illnesses is to use the three Ds - use insect repellent that contains DEET, picaradin or lemon oil of eucalyptus, drain any standing water, and dress in long clothing.
DCHHS West Nile prevention activities include surveillance, source reduction, larvaciding (killing mosquito larvae or wigglers), adulticiding (spraying for adult mosquitoes), and public education. Dallas County has enhanced is early detection capability through the use of gravid traps for mosquito collection and global positioning systems equipment provided by the Texas Department of State Health Services (DSHS).
