High mosquito populations yield positive West Nile Virus samples

The Massachusetts Department of Public Health (DPH) has announced that routine surveillance shows a larger population than normal of Culex mosquitoes that can carry the West Nile Virus (WNV), and that positive WNV samples have occurred earlier this year than last year. The July population was recorded especially high (almost three times higher than last year) and rendered positive WNV samples in Brookline, Worcester and Millbury. So far, no tests for WNV or Equine Encephalitis have yielded positive results in Carlisle, but the DPH is advising all Massachusetts residents to take precautions against mosquito bites. Be aware of peak mosquito hours, often dusk to dawn; wear protective clothing out of doors; apply insect repellent before going out of doors; drain standing water from around your home; keep screens in good repair; report any dead birds you find.
