West Nile Virus Detected in East Providence, Westerly, and West Greenwich

Published on Thursday, August 21, 2025

PROVIDENCE, RI – The Rhode Island Department of Environmental Management (DEM) and Rhode Island Department of Health (RIDOH) have confirmed detections of West Nile Virus (WNV) in the state. The virus was found in mosquito samples collected by DEM in East Providence, Westerly, and West Greenwich on August 12 and tested by the Rhode Island State Health Laboratories. The other samples collected statewide showed no signs of Eastern Equine Encephalitis (EEE) virus, Jamestown Canyon Virus (JCV), or additional WNV. Check RIDOH’s arboviral surveillance data webpage for updated weekly test results. 

WNV is the main mosquito-borne disease in the US. While most people with WNV don’t get sick, about one in five people who are infected develop a fever and other symptoms. There are no vaccines to prevent or medications to treat WNV in people. For more information about WNV, visit www.health.ri.gov/wnv
