Nashville has reported its first human case of West Nile Virus for 2025, according to the Metro Public Health Department (MPHD). The individual, who has not been identified for privacy reasons, is a resident of South Nashville and has no recent travel history. The news comes amid increasing West Nile Virus activity observed in the local mosquito population, with the pests showing higher infection rates in the area.
MPHD's Pest Management Team has been actively monitoring the situation, setting traps and testing mosquitoes throughout the season. They've found the virus in specimens from 27 different trapping sites across the county. Affected neighborhoods have been alerted, as health officials disseminate notifications to homes potentially at risk. The Team is also applying larvicides to stagnant water bodies, aiming to curb the mosquito lifecycle and stave off future population surges.
In their public notice, MPHD issued advice on how residents can protect themselves and assist in controlling the mosquito population. "Limiting time outdoors at dusk and nighttime hours when mosquitoes are most active" is among the key recommendations. They also advise wearing protective clothing and using CDC-approved mosquito repellents such as DEET, Picaridin, and Oil of Lemon Eucalyptus. Moreover, residents are encouraged to eliminate standing water around their homes, a known breeding ground for mosquitoes, and to ensure that window and door screens are in good repair to keep the insects out.
The CDC indicates that most West Nile Virus infections are asymptomatic. Still, those who fall ill often manifest flu-like symptoms, ranging from fever and body aches to vomiting and diarrhea, usually starting two to six days post-infection. The MPHD has underscored the importance of seeking medical attention if symptoms develop, as severe cases can lead to more significant health issues, including impacts on the central nervous system, hospitalization, or even death. More information on the situation and precautions can be found on the MPHD website.
