SouthernWorldwide.com – Health officials in Nashville are urging residents to take precautions against mosquito bites following the detection of West Nile virus in mosquitoes for the first time this year.
The Metro Public Health Department (MPHD) confirmed that the virus was identified in a mosquito pool collected near Cass Street in North Nashville. This marks the city’s initial detection of West Nile virus in 2026 and represents the earliest positive mosquito sample recorded for the season.
This discovery comes on the heels of elevated West Nile virus activity observed in mosquito pools during 2025, a year that also saw one confirmed human case of the virus.
“We can all play a role in reducing the presence of mosquitoes in our community, making our outdoor areas both more pleasant and safer from mosquito-borne diseases like West Nile virus,” stated Dr. Sanmi Areola, director of health at the Metro Public Health Department, in a statement to Fox 17.

“As our team educates those in the area where West Nile virus was found, we hope the rest of our community does what they can to protect themselves and their families from mosquitoes this summer.”
According to the Centers for Disease Control and Prevention, West Nile virus is the most prevalent mosquito-borne disease in the United States. A majority of individuals infected with the virus remain asymptomatic. However, approximately one in five will experience symptoms such as fever, headaches, body aches, vomiting, diarrhea, or a rash.
Fewer than 1% of infected individuals develop a serious neurological illness that can impact the brain or spinal cord. Older adults and those with compromised immune systems are at the highest risk for severe complications.
Public health officials regularly conduct mosquito trapping and testing throughout the summer months to monitor for West Nile virus activity. A positive mosquito sample does not automatically indicate that individuals in the vicinity will contract the virus, but it serves as an important early alert that the virus is actively circulating in the local area.
In response to the positive test result, the MPHD has initiated several measures. Crews are distributing educational flyers in the affected neighborhood, intensifying mosquito trapping efforts, monitoring areas with standing water, and applying larvicide as needed to help curb mosquito populations. The department has clarified that it does not engage in spraying insecticide to eliminate adult mosquitoes.

Additionally, residents have the option to request a complimentary backyard inspection from the department’s Pest Management team. This service aims to identify potential mosquito breeding grounds around homes.
Health officials strongly recommend eliminating standing water from various outdoor sources. This includes bird baths, flowerpots, buckets, discarded tires, children’s toys, and any other containers that can accumulate water where mosquitoes lay their eggs. Keeping overgrown vegetation around homes trimmed can also contribute to reducing mosquito activity.
To further prevent mosquito bites, the health department advises using EPA-approved insect repellents that contain DEET, picaridin, or oil of lemon eucalyptus. Wearing long sleeves and pants when outdoors, particularly during the peak mosquito activity hours around dusk and dawn, is also recommended. Ensuring that window and door screens are in good repair is another crucial preventive measure.
Officials emphasize that by reducing mosquito breeding sites around homes, the risk of West Nile virus and other mosquito-borne illnesses can be significantly lowered throughout the entire community.
