West Nile virus found in R.I. for first time this summer

Mosquitoes trapped in Tiverton and Pawtucket on July 30 have tested positive for West Nile virus, the Department of Environmental Management announced Friday.

It was the first time this year that West Nile virus has been confirmed in Rhode Island, although positive tests had already been recorded in Connecticut and Massachusetts. The DEM noted that mosquito-borne diseases are more prevalent in late summer and early fall.

The remaining 157 mosquito samples from 39 traps set on July 30 tested negative for both West Nile virus and Eastern Equine Encephalitis; however, EEE had been found in four other mosquito samples tested in the state earlier this summer.

The DEM advises people to use EPA-approved bug spray; minimize outdoor activity at dawn and dusk; put insect netting over strollers and playpens; wear long sleeves and long pants whenever possible; remove standing water; clean gutters and downspouts; and change water in birdbaths at least twice a week.

 The agency also notes that horses are particularly susceptible to West Nile virus and EEE.
