Rhode Island reports first human West Nile virus case of 2026, likely contracted out of state

A Washington County resident in their 60s is recovering in the hospital. Health officials said the person had traveled to an area where the virus was spreading.

Rhode Island has recorded its first human case of West Nile virus in 2026, the state Department of Health and the Department of Environmental Management said Thursday.

The patient is a Washington County resident in their 60s who began showing symptoms in early September, according to the health department. The person has been recovering in the hospital and is expected to be released, the department said. The Centers for Disease Control and Prevention confirmed the positive test.

The patient had traveled to an area where West Nile virus was actively spreading, and the infection was most likely picked up outside Rhode Island, health officials said.

The statewide risk of West Nile virus is low because mosquito numbers fall off at this point in the season, the department said. Some risk will remain until the entire state has a hard frost, which officials define as three straight hours below 32 degrees, cold enough to kill adult mosquitoes.

West Nile virus is the leading cause of mosquito-borne disease in the continental United States, and there is no vaccine or treatment for it in people. Most people who are infected do not feel sick, according to the department. About one in five develop a fever and other symptoms, and about one in 150 develop a serious illness that can be fatal.

No cases of Eastern equine encephalitis, a rarer but more deadly mosquito-borne virus, have been found in people or mosquitoes in Rhode Island in 2026, the department said. The state has finished its mosquito trapping and testing for the season.
