Tick Prevention in New England
As ticks and tick-borne disease continue to increase in the region, it’s incredibly important to be tick-aware. The New England Center of Excellence in Vector-borne Diseases (NEWVEC) has rolled out “Project ITCH (“Is Tick Control Helping?”). They are asking New England residents to complete a survey about tick prevention methods that you are doing to reduce tick bites and the transmission of disease. Please help them gather this important information so we are better able to identify and manage the spread of tick-borne illnesses.
