2nd human West Nile case confirmed in Knox County

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

The first confirmed human case of West Nile in the county in 2012 was reported in early September, and these marked the first such cases since September 2009.

Officials have been working all summer to decrease the mosquito population, and recent cool nights were expected to help as well.

The Knox County Health Department has found the virus in their several of their testing pools in the county.

Every time they receive a positive test in the water, they spray the area around it. They also use mosquito traps and larvacide.

Knox County Health Department Director Dr. Martha Buchanan told 10News earlier in September that there is no way for people to tell which mosquitoes are carrying the virus.

The Health Department recommends avoiding the outdoors between dusk and dawn, wear protective clothing if you can, and use a bug spray that contains DEET.

By keeping your grass cut and emptying any standing water, you can also help prevent the mosquitoes from breeding.

People over 50 are the most high-risk age group to contract the virus.

Symptoms will appear a few days after exposure, but the bites will look like any other mosquito bite.

The virus usually shows up in the form of fever, body aches, head ache and nausea.

In Tennessee, 24 human cases have been reported so far this year, according to data from the state's Department of Health.

The cases were reported in 12 other counties statewide, including Greene County and Hawkins County in East Tennessee.
