2010 Metro Mitigation Plan

Human cases have been reported in all states except Maine, Oregon, and
Washington;
Neuroinvasive disease and high mortality is the most common among people over
60 years of age; There is an impressive westward movement of most intense WNV
transmission;
No currently approved and effective vaccine and no currently approved and
effective antivirals exists; and
Mosquito control reduces the WNV risk of human infection.

WNV is seemingly at its worst during a state‟s second year of exposure. If this continues
to hold true, Nashville-Davidson County may be past the peak period, while still
remaining susceptible.
