Why Is This Important?
Lyme disease is caused when an infected tick bites a person. The dynamics of Lyme disease are influenced by a range of factors, including land use, populations of mouse and deer hosts, the number of infected ticks, and climate. Warming temperatures are thought to increase tick abundance while also lengthening their seasonal period of activity. Beyond Lyme disease, a warmer climate may allow other vectors of disease, such as Lone Star ticks, to expand their ranges into Vermont.
