The Metro Public Health Department announced on Wednesday they are investigating the first human case of West Nile virus in Davidson County.
Health officials said the affected individual, whose identity was not released, lives in the Antioch area.
No additional information was immediately released regarding the case.
Also on Wednesday, the health department reported additional mosquitoes recently collected have also tested positive for the virus.
The mosquitoes were captured near the intersection of Myatt Drive and Anderson Lane in Madison, near the intersection of Apache Trail and Packard Drive in Antioch and near the intersection of Lebanon Road and Old Hickory Boulevard in Hermitage.
“We need to reduce breeding sites, but we need to prevent mosquito bites, so that even when we have activity in mosquitoes, it doesn't necessarily translate to human cases,” toxicologist Dr. Sanmi Areola said.
On Thursday, health department employees spent time going door-to-door giving residents information on how to prevent mosquito bites.
“Anytime we see increased activity, our response is to educate the public,” Areola said.
The health department began trapping the insects in May.
Currently, the West Nile virus has been confirmed in batches of mosquitoes found in Antioch, Goodlettsville, Hermitage, Madison and north and south Nashville.
The Health Department's Pest Management staff has increased trapping efforts in the areas where the mosquitoes tested positive.
Staff will also continue to monitor standing water in the area and apply larvicide when mosquito larvae are present.
In an effort to prevent mosquito bites, health officials recommend limiting time outdoors at dusk and nighttime hours, in addition to wearing mosquito repellent, as well as shoes, socks, long sleeve shirts and pants.
Health officials said currently there are not any plans to spray neighborhoods for the insects.
A spokesperson said cooler temperatures and the end of mosquito season should significantly slow down the insects' activity.
