Second positive test for West Nile virus in Rhode Island

Rhode Island has its second human case of West Nile virus in 2025, according to recent test results.

The Rhode Island Department of Health (RIDOH) confirmed Tuesday that a Providence County resident in their 50s tested positive for the mosquito-borne virus. While the individual began showing symptoms in early October, they have since made a full recovery.

The state’s first human case of West Nile virus this year was reported on September 25.

The virus was also detected in a mosquito sample collected in East Providence on July 21, according to a joint statement from the Department of Environmental Management (RIDEM) and RIDOH.

West Nile virus is a mosquito-borne illness that primarily spreads through the bite of infected mosquitoes. While most people infected with the virus do not develop any symptoms, some may experience mild flu-like symptoms such as fever, headache, body aches, and fatigue. In rare cases, the virus can lead to serious neurological complications, including encephalitis or meningitis, which can be life-threatening. There is currently no vaccine or specific treatment for West Nile virus, so prevention focuses on reducing mosquito exposure by using insect repellent, wearing long sleeves and pants, and eliminating standing water where mosquitoes breed. The virus is most active during the warmer months, and the risk decreases once temperatures drop and mosquito populations decline.
