Summer is winding down. The risk of West Nile in Rhode Island, is not.

PROVIDENCE, R.I. — The calendar may be turning toward fall, but Rhode Island’s mosquitoes have not received the memo.

West Nile virus was detected in mosquito samples collected in Providence and Cranston, state health and environmental officials announced Thursday. The samples were collected Aug. 17 and later tested by the Rhode Island State Health Laboratories.

The findings were enough for officials to repeat a warning that is easy to ignore late in the summer: The risk of West Nile virus remains high across Rhode Island.

No new human infection was announced with the mosquito results. That distinction matters. Finding the virus in mosquitoes does not mean someone nearby has contracted it, but it does tell health officials that the virus is circulating and capable of reaching people.

Most people infected with West Nile virus never experience symptoms. About one in five develops a fever or other illness, according to health officials. In rarer cases, the virus can cause serious neurological disease.

Older adults and people with weakened immune systems face a greater risk of severe illness. There is no vaccine available for people and no medication specifically designed to treat a West Nile infection.

The positive samples came from two of Rhode Island’s most populated communities, but the state’s warning is not limited to Providence and Cranston. Officials continue to classify the risk as high statewide.

Other mosquito samples collected around Rhode Island showed no evidence of Eastern equine encephalitis, Jamestown Canyon virus or additional West Nile virus, according to the Department of Environmental Management.

For residents, the recommended response is not complicated. Use insect repellent, cover exposed skin when practical and be especially careful around dawn and dusk.

Then walk around the yard.

A forgotten bucket, clogged gutter, flowerpot, tire or children’s toy can hold enough water for mosquitoes to breed. Birdbaths and other outdoor containers should be emptied or refreshed regularly, and damaged window screens should be repaired.

The precautions may sound familiar because they are. Mosquitoes are not particularly innovative. They need water, access and an opportunity to bite. Removing one of those can make a difference.

The important part is not abandoning those habits simply because September is approaching.

Mosquito activity can continue into the fall as long as temperatures remain favorable. For now, Rhode Island’s summer may be nearing its unofficial end, but the state’s West Nile warning remains very much in season.

Rhode Island residents can review current mosquito-testing information and prevention guidance through the Department of Environmental Management and Department of Health.
