PROVIDENCE, R.I. (AP) — The first mosquitoes tested in Rhode Island for West Nile virus and eastern equine encephalitis show no sign of disease.
The state Department of Environmental Management said Monday that 67 of the 99 mosquito pools collected from 20 traps set statewide on June 10 tested negative for both diseases.
Results from the remaining 32 pools are pending at the state health department's laboratory.
Environmental officials trap mosquitoes and the health department tests them regularly during mosquito season.
The DEM normally reports mosquito test results weekly, with additional reports as necessary. Positive mosquito test results generally trigger additional trapping to assess risk.
Last year, six pools of mosquitoes tested positive for eastern equine encephalitis and five tested positive for West Nile.
