News Summary
A mosquito sample in East Providence has tested positive for West Nile virus, marking the 12th case in Rhode Island this summer. This recent finding adds to multiple positive samples across several municipalities. Health officials continue to emphasize the high risk associated with West Nile virus and urge residents to take precautions against mosquito bites. Preventative measures are crucial to reduce the spread of this virus, which poses serious health risks, especially to vulnerable populations.
East Providence, Rhode Island – A mosquito sample collected on September 2, 2025, has tested positive for West Nile virus, marking the 12th confirmed case of the virus in Rhode Island this summer. This most recent positive finding was processed by the Rhode Island State Health Laboratories and follows the detection of the virus in East Providence just one week prior.
In addition to East Providence, positive samples have been reported in other municipalities, including Johnston, East Providence, and Cranston, from tests conducted the week before the latest result. Earlier in the summer, recorded instances of the virus also included Westerly, West Greenwich, and another earlier detection in East Providence, along with a case in Bristol.
Currently, Rhode Island’s overall risk level for West Nile virus remains high for the entire state, which is concerning for public health officials. Though most individuals infected with the virus do not exhibit any symptoms, approximately 20% of people may develop mild symptoms like fever and headaches. Severe cases of West Nile virus can potentially lead to serious illnesses such as encephalitis or meningitis, with a notable 10% fatality rate associated with severe infections, particularly among the elderly and immunocompromised populations.
The state has reported a notable increase in West Nile virus activity throughout the summer. The first positive sample of the season was detected on July 21, 2025, and the largest cluster of positive samples emerged on August 12, with the virus noted in East Providence, Westerly, and West Greenwich. Mosquito samples collected on August 25 have also indicated positive findings in North Attleborough, which is categorized as having a moderate risk level for the virus.
Health officials have confirmed the presence of the Culex mosquito, a known vector for transmitting West Nile virus, among the positive samples. Testing of these insects also confirmed negative results for other diseases, such as Eastern Equine Encephalitis (EEE) and Jamestown Canyon Virus.
In the wider context, as of August 26, 2025, there have been 433 reported cases of West Nile virus across the United States, over half of which are categorized as neuroinvasive illnesses, highlighting the significant public health challenge posed by this mosquito-borne disease. West Nile virus is recognized as the most commonly identified mosquito-borne illness in the United States.
Given the ongoing presence of the virus and the high risk levels statewide, public health officials are strongly advising residents to take preventative measures against mosquito bites. These measures include the use of EPA-registered insect repellents, wearing protective clothing, and eliminating any standing water around homes to reduce potential mosquito breeding sites.
The critical nature of the West Nile virus outbreak this summer, supported by multiple confirmed cases and ongoing high-risk assessments, underscores the importance of vigilance in personal and community health practices to combat the spread of this virus.
