Warmer weather has arrived, along with new questions and concerns over ticks, Lyme disease, and the large number of U.S. cases reported in the Northeast. 

2015-dot-map-CDC-269568-edited250x193.jpgAccording to the CDC, there are 30,000+ cases of Lyme disease reported each year. Since national Lyme surveillance began, in the early 1990s, the number of annual Lyme cases has increased. Seasonal variations have contributed to what appears to be a northward expansion. These shifts are suspected to be associated with global climate change. Increases in temperature, changes in precipitation patterns, increases in extreme weather, and rising sea levels are capable of influencing the life cycle, distribution, and prevalence of vector-borne diseases by altering habitat availability and reproduction rates. Reasons contributing to the seasonal variability of tick activity and the probable northeast spread of Lyme disease are tick and host habitat range expansion, longer seasons for tick activity, and increased human exposure seasonally.
