The number of uninsured Tennesseans has dropped to its lowest total in four years, according to a University of Tennessee study released on Monday.

The Knox County Health Department on Friday confirmed that a human case of West Nile Virus had been reported in Knox County.

They're not releasing any details about the case, but Knox County Health Department Director Dr. Martha Buchanan said she expected to see a case of West Nile here and is not surprised that it has happened with cases popping up around the country.

This is the first confirmed case of West Nile in the county in 2012, and the first one reported since September 2009.

Officials have been working all summer to decrease the mosquito population.

Flu season is just around the corner, and already drug stores and doctor's offices have supplies of this year's vaccine.

The shots will be available to patients by the end of the month.

But if you get your shot now, will you be protected all season? The Centers for Disease Control says "yes."

The CDC recommends that people get their shots as soon as possible. It suggests everyone from six months old and older get a yearly vaccine.

One local flu shot clinic opens Tuesday.
