KEY FINDINGS FOR PENNSYLVANIA: CLIMATE CHANGE AND HEALTH
1) Case reports of Lyme disease (tick-borne) have gone up five-fold in Pennsylvania in the past decade, as winters have warmed

» Tick populations – that can transmit Lyme disease -- are projected to increase with warmer winters (Brownstein et al. 2005).
» In 2008, more than 3,000 Pennsylvania residents contracted Lyme disease.
» In 2009, that number more than doubled, to close to 8,000 cases, and case reports for 2010 indicate another uptick (WHYY 2010).
