To determine the worst states for Lyme disease, 24/7 Wall St. reviewed the average annual incidence of Lyme disease between 2016 and 2018 in every state and Washington D.C. from the Centers for Disease Control and Prevention, National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), and Division of Vector-Borne Diseases (DVBD). The 14 states and D.C. are those that reported a “high incidence” of Lyme disease, defined by the CDC as an average incidence of at least 10 confirmed cases per 100,000 persons for the previous three reporting years. We also reviewed annual total cases, which includes confirmed as well as probable cases, for each year between 2009 and 2018 in every state.
The percentage of adults who are physically active came from County Health Rankings & Roadmaps, a Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute joint program. The percentage of state residents who do not have health insurance (uninsured rate) are from the U.S. Census Bureau’s 2018 American Community Survey.
