Why We Do What We Do

The incidence of tickborne illness in the US has been rising in recent years as we experience milder winters and expanding tick habitats. On Martha's Vineyard, we spend significant time outdoors; in our yards, on beaches, hiking, biking, exploring, playing, horseback riding, farming, working, socializing, fishing. This time spend outdoors puts us at risk for tick bites and, therefore, tickborne illness. Additionally, tickborne illness is now a year round concern. 

Locally, we contend with Lyme Disease, Babesiosis, Ehrlichiosis, Anaplasmosis, Rocky Mountain Spotted Fever, Tularemia, Alpha-Gal Syndrome, Powassan Virus, and Borrelia Miyamotoi Disease.

Given our unique island ecosystem and geography—including an over abundance of white tailed deer, the primary breeding ground for ticks—Dukes and Nantucket Counties have the highest rates of tickborne illness in Massachusetts.
 

  • Lyme disease (our biggest issue) is 11x more common on MV than elsewhere in the state.

  • Our rates of Ehrlichosis is 140x higher than state levels.

  • Rocky Mountain cases are over 185x higher than state levels.


Alpha-Gal Syndrome, which became reportable to state in April of 2026 to help us quantify cases, is likely to surpass our number one tickborne illness on the island.


The fact is, either you or someone you know has been, or will be, affected by tickborne illness. These illnesses not only have significant physical impacts, but often result in emotional distress, including depression and anxiety. They make it difficult to enjoy the things we love such as spending time outdoors. Alpha-Gal Syndrome can be socially isolating as we fear accidentally encountering food that that trigger an uncomfortable or potentially dangerous allergic response at gatherings or restaurants.

At best, many of these conditions are short-lived and easily treated with antibiotics coupled with supportive and other kinds of care. At worst, they can be life threatening if not recognized and managed quickly and properly and can have longer term health implications . They disrupt our health and wellbeing, our workforce and our economy. 

At TickWiseMV, we want to our patients to feel they have quick and personalized access to help with tick-related health issues, be it for diagnosis and treatment, tick checks or tick removal, management of bites or simple conversation and education about tickborne illness and bite prevention.  

The problem of tickborne illness is REAL and can be scary. BUT, prevention of tick bites works, and tickborne illnesses can be managed in a way that need not ruin our enjoyment of life on this beautiful island we call home.
