The latest round of mosquito samples collected in Rhode Island have tested negative for West Nile virus just days after the disease was confirmed in the state for the first time this year.
The Rhode Island Department of Environmental Management reported last week that it found mosquitoes carrying the virus in Pawtucket from traps set on July 25.
The agency, which traps mosquitoes weekly, said Tuesday that remaining samples from the same 37 traps have all tested negative for the West Nile virus and another mosquito-borne disease, eastern equine encephalitis.
It's still waiting on test results from traps set on Aug. 1.
There have been no human cases in the state this year.
