West Nile Virus detected in Davidson County for the first time in 2025
NASHVILLE, Tenn. (WKRN) — The Metro Public Health Department's Pest Management Team has reported the presence of West Nile Virus in Davidson County.
The team said that the virus was detected in a mosquito pool; the trap for the pool had been established off Neelys Bend Road in Nashville's Madison neighborhood. This is the first detection of West Nile Virus this year with no human cases reported so far in 2025.
The Metro Public Health Department said that last year, there was a high level of virus detected in area mosquito pools. The department first started monitoring the mosquito traps for the 2024 season at the end of April.

In all, the Pest Management team captured and tested more than 39,000 mosquitos across 32 Davidson County sample sites. By mid-October, the virus had been detected at every sampling site in the county.
'Keeping our community safe and healthy means monitoring mosquito-borne diseases like West Nile Virus and informing those who might be at risk,' Dr. Sanmi Areola, Metro Public Health Department's Director of Health said. 'Education is a big part of our work, ensuring that we know that we all have a roles to play in reducing breeding of mosquitoes and preventing bites so that those who are at risk know what they can do to protect themselves and their families.'
The Pest Management Team revisits impacted sites and sets additional traps, monitoring standing water and applying larvicide when they see mosquito larvae. However, the department does not spray to kill adult mosquitos.
The health department sends fliers to residences in impacted areas with steps to protect against mosquito bites and reduce standing water, which is where mosquitos can lay eggs.
There are some other steps you can take, including:
Limit time outdoors at dusk and nighttime, when mosquitos are most active.
Wear a mosquito repellant approved for use by the U.S. Centers for Disease Control and Prevention, including products that contain Picardin, Oil of Lemon Eucalyptus and DEET. The Environmental Protection Agency has a tool that helps you find the right repellant for you; you can find that tool here.
Wear shoes, socks, long-sleeve shirts and pants when mosquitos are the most prevalent. Additionally, any clothing you wear should be lightly colored and made of tightly-woven material to keep mosquitos away from the skin. Any pant legs should be tucked into shoes or socks and collars should be buttoned.
Make sure any windows and doors have screens that are in good repair.
⏩
The department encourages you to check things like bird baths, tires or other backyard toys and trim overgrown vegetation to discourage breeding.
If you would like a free backyard inspection, you can call the Metro Public Health Department's Pest Management Team at 615-340-5660 to learn about places on your property where mosquitos could easily breed and multiply.

Williamson County veterinary clinic warns cat owners of deadly Bobcat Fever
FAIRVIEW, Tenn. (WKRN) — A Williamson County veterinary clinic is warning cat owners about the dangers of a deadly, tick-borne disease after seeing a surge in cases over the last two weeks. Bobcat Fever, also known as Cytauxzoonosis, is a deadly parasite transmitted to cats by the Lone Star tick, which is known to have one white dot on it. The parasite normally lives in bobcats without causing illness, however, when domestic cats are infected, they often die within 72 hours of first symptoms, which may include fever, lack of energy, decreased appetite, and yellow skin or eyes, deadly, according to Fairview Animal Clinic. Over the last few weeks, Fairview Animal Clinic has seen nine cases of Bobcat Fever. 'We haven't had this many cases in such a short two-week period, so I'm kind of nervous about what's going to happen over this the rest of the summer since it's a long tick season, and it goes all the way to the fall,' said Dr. Eric Fold, associate veterinarian at Fairview Animal Clinic. More than a dozen arrested by Lebanon police in 'targeted operation' Dr. Simone Godwin, a relief veterinarian at Fairview Animal Clinic, said even with aggressive treatment including hospitalization, antimicrobials, and supportive care, the disease is often fatal. In this recent cluster of cases at Fairview Animal Clinic, 78% of cats died or were euthanized. Of the five that were treated, only one survived. Additionally, one cat who did not receive treatment survived. 'So far, we've only had a 20% success rate, and it's really hard on the cats,' Fold said. 'They're very, very sick, and a lot of owners actually elect to euthanize because of the poor prognosis, the just the state of their cat when they bring it in, and it's pretty expensive. The medications are very, very pricey to obtain.' Fold said early detection is crucial as survival rates drop drastically without treatment. 📧 Have breaking news come to you: → 'We've got to get our cats on the prevention, and if you do notice any signs of illness in your cat, bring it in as fast as you can that way we can get them started,' Fold said. 'We've seen some success with it, but it's still a very difficult disease to try to manage.' Dr. Danielle Grigsby, owner of Fairview Animal Clinic, said keeping cats indoors and on year-round flea and tick prevention is the best way to prevent Bobcat Fever and a host of other issues that outdoor cats are at risk for, like trauma, eating something toxic, and other infections. Since some of the fipronil products can take up to 48 hours to actually kill the tick, Fold said the clinic is recommending some of the prescription-based prevention products, such as the Seresto® Flea and Tick Collar for Cats. 'The problem that we're seeing with the Seresto® collar is that the owners actually aren't keeping them tight enough on the cats so they don't actually have contact with the skin, so it has to be tight enough to actually transmit the medication to the cat,' Fold said. 'Just make sure that you go by the label instructions, but it's usually going to be one to two fingers tight, where you can only slip one or two fingers between the cat and the collar. ⏩ Even though the disease does not affect dogs or humans, veterinary experts said both can carry ticks indoors which could ultimately infect a cat. 'The life expectancy of outdoor cats is only 2-5 years, versus up to 15 for indoor cats, Godwin said. 'Your veterinarian can help you make the best decision on prevention products and lifestyle changes to make sure your cat lives a long and healthy life.' Copyright 2025 Nexstar Media, Inc.
