West Nile Virus



West Nile Virus (WNV) is a potentially serious virus transmitted by mosquitoes that, when contracted by humans, affects the central nervous system. While the large majority of people exposed to West Nile Virus never contract the disease, those who do can suffer very serious symptoms that in extreme cases can result in hospitalization or even death. The elderly, the very young, and persons with underlying health conditions affecting their immune system can be more susceptible. WNV is a blood-borne disease and is not spread through casual contact. Public health officials declared 2012 the worst season on record for WNV in North Texas. More than 30 people in Lewisville came down with WNV in 2012. There are simple precautions people can take to protect themselves and their families from the disease.

Residents also are encouraged to report standing water on city-maintained property by calling Code Enforcement at 972.219.3480.  Reports can also be made online under "Requests/Health Concern."  For additional questions residents can call 972.219.3776.
