News Summary
Rhode Island officials have announced the first detection of West Nile virus this year, following the identification of the virus in a mosquito sample collected in East Providence. The sample, collected on July 21, tested positive for the virus. Health officials urge residents to take precautions against mosquito bites and actively eliminate standing water to reduce mosquito breeding sites.
East Providence – Rhode Island officials confirmed the first detection of West Nile virus for the year on Thursday, following the identification of the virus in a mosquito sample collected in East Providence. The sample, which tested positive for the virus, was collected on July 21 as part of the routine mosquito surveillance conducted by the Rhode Island Department of Environmental Management (DEM).
The mosquito sample that contained the virus was confirmed at state laboratories and was identified as belonging to the Aedes albopictus, commonly known as the Asian tiger mosquito. This species is recognized as a carrier of West Nile virus, raising concerns among health officials.
This recent detection is comparable to last year when Rhode Island reported its first positive sample around July 15. For 2025, a total of 192 mosquito samples—representing 2,838 individual mosquitoes—were tested, with only the East Providence sample showing signs of West Nile virus. Notably, no samples tested positive for Eastern Equine Encephalitis (EEE) or Jamestown Canyon Virus.
West Nile virus is the most widespread mosquito-borne disease in the United States. While many infected individuals remain symptom-free, approximately 20% will experience symptoms including fever, headache, and body aches. In a smaller percentage of cases, infections can lead to serious neurological complications such as encephalitis or meningitis. The fatality rate for severe cases is around 10%, predominantly affecting adults over 60 years of age and individuals with weakened immune systems.
According to preliminary data from the Centers for Disease Control and Prevention (CDC) for 2025, there have been 53 reported cases of neuroinvasive West Nile virus out of 98 total cases nationwide. Between 1999 and 2024, the CDC documented a total of 60,992 cases of West Nile virus in the United States, which resulted in 3,134 deaths.
To mitigate the risk of infection, Rhode Island health officials are advising residents to take precautionary measures. These recommendations include wearing insect repellent containing DEET, as well as donning long sleeves and pants, particularly during peak mosquito activity periods at dawn and dusk. Residents are also encouraged to eliminate standing water around their homes to reduce potential breeding sites for mosquitoes.
For those interested in the ongoing mosquito testing efforts, the Rhode Island Department of Health provides weekly updates on its website, offering insights into mosquito activity and any new findings. Additionally, comprehensive information and prevention tips focusing on mosquito control can be accessed via the Department of Health and the Department of Environmental Management’s official websites.
As mosquito season progresses, health officials will continue monitoring the population and testing for various mosquito-borne viruses. Community awareness and proactive measures remain vital in preventing the spread of diseases like West Nile virus.
