West Nile Virus and EEE

As of October 28th, the risk of West Nile Virus in Newton was reported as “Moderate.”  The EEE risk in eleven towns in western Middlesex County (including Framingham, Sudbury, and Wayland) was either “Critical” or “High”.  The EEE risk in Newton and most surrounding towns was “Low”.  Lincoln, Weston, and Natick were at the “Moderate” risk level. Twelve Massachusetts residents have tested positive for the disease, and three people have died. Each summer, the Massachusetts Department of Public Health (DPH) tests mosquitoes to see if they are carrying West Nile Virus (WNV) or Eastern Equine Encephalitis (EEE or “Triple E”).  According to DPH, these viruses “can cause illness ranging from a mild fever to more serious disease like encephalitis or meningitis.” DPH posts the test results on web pages that assign a category (ranging from “Remote” to “Critical”) to the risk posed by each virus in each community in the state.
