WHAT IS THE RISK OF GETTING WEST NILE VIRUS IN MIDDLE TENNESSEE AND DOES SPRAYING HELP?

The risk of human West Nile virus in 2002-2006 in the 6 neighboring counties which have NO MOSQUITO CONTROL* was .16 per 100K. Davidson County was .11 per 100K. The rate of West Nile is extremely low and there is no significant difference in disease incidence whether we spray or not in Middle Tennessee.

*Two exceptions we've found are the city of Murfreesboro they do not spray but larvicides and the city of Hendersonville which sprays and larvicides currently but we have not confirmed how long they have been doing this.
