13 Batches of Mosquitoes Test Positive for WNV, One Human Case Reported in Davidson County


Multiple batches of mosquitoes collected by the Metro Public Health Department's Pest Management Division have tested positive for West Nile virus.  One human case was reported this past week in Davidson County.  The individual is expected to recover from the illness. The batches of mosquitoes were trapped in the following locations:

  • Antioch – Near the intersection of Edge O Lake Drive and Murfreesboro Pike
  • Green Hills – Near the intersection of Woodlawn and Estes Road
  • Old Hickory – Near the intersection of Swinging Bridge Rd and Ensley Ave.
  • Hermitage – Near the intersection of Andrew Jackson Pkwy and Highland View Dr.
  • Hermitage – Near the intersection of Anderjackson Pkwy and Albany Dr.
  • Donelson – Near the intersection of Donelson Pike and Lakeland Dr.

  • Goodlettsville – Near the intersection of Gallatin Pike N. and Alta Loma Rd.
  • East Nashville – Near the intersection of Eastland Ave. and Preston Dr.

  • West Nashville – Near the intersection of 28th Ave and Charlotte Ave.
  • South Nashville – Near the intersection of Polk Ave. and Nolensville Pike
  • Waverly/Belmont – Near the intersection of 12 Ave. South and Acklen

The Health Department's Pest Management staff will visit areas in the coming week to pass out mosquito protection and prevention educational materials and monitor standing water looking for mosquito larvae.  Staff will apply a granular larvicide to any areas where mosquito larvae are present. There are no plans to spray at this time.

Staff began trapping mosquitoes in all parts of Davidson County the first week in May. Health Department staff sends the mosquitoes to the Tennessee Department of Health's lab for testing.

The Health Department recommends taking the following steps to protect against biting mosquitoes, including:

  • Limit time outdoors at dusk and nighttime hours when mosquitoes are present.
  • If you must be outdoors then wear a mosquito repellent that is approved for use by the CDC – those include products that contain DEET, Picaridin, and Oil of Lemon Eucalyptus.
  • Wear shoes, socks, long sleeve shirts and pants when outdoors during dusk to dawn when mosquitoes are most prevalent.  Clothing should be light colored and made of tightly woven materials to keep mosquitoes away from the skin.  Pant legs should be tucked into shoes or socks, and collars should be buttoned.
  • Make sure your windows and doors have screens and are in good repair.

Health Department officials recommend taking steps to reduce mosquito breeding areas.  This includes:

  • Reduce or eliminate all standing water in your yard – especially in children's toys, bird baths, clogged gutters, tires, flowerpots, trashcans, and wheelbarrows.
  • Aerate ornamental pools or stock them with Gambusia fish.
  • Apply mosquito dunks in standing water areas on your property.
  • Cut back overgrown vegetation (mosquito hiding areas).

Health Department staff began monitoring standing water in all areas of Nashville in late February.  Staff applies larvicide when mosquito larvae are present to kill the larvae before they become adult mosquitoes.

Please visit the Health Department's website and Facebook and Twitter pages for updates on West Nile Virus and Zika.  Davidson County residents that are having mosquito problems can call 615-340-5660 to arrange to have a Pest Management staff member come and inspect your property and provide mosquito control and prevention advise.  Pest Management staff will check your property for standing water and apply the larvicide if mosquito larvae are present.
