Physicians are noticing an influx of patients whose illnesses are directly or indirectly related to global warming

Growing up in southwestern Pennsylvania, Patrice Tomcik had never heard of Lyme disease — an infectious, flu-like illness transmitted by ticks.

But in the last few years, five of her friends have caught it, she’s had to have her dog vaccinated and she regularly finds herself pulling ticks off her children. It can be disconcerting, she said, having to worry about an illness that she had never been exposed to in the past.

“It’s getting warmer, so the season for ticks is lasting longer,” said Tomcik, a field consultant with Moms Clean Air Force. “There are so many more of them, and they just don’t die off. It’s a big issue here in Pennsylvania, because we have so much wood. Our family has 29 acres of land out in the woods, and I’m picking ticks off my dog and my kids like I’ve never seen before.”

Lyme disease isn’t the only contagious illness that is venturing into new territories under a shifting climate. Across the country, physicians are noticing an influx of patients whose illnesses, they say, are directly or indirectly related to climate change. Now, 11 medical associations — representing around half the doctors and physicians in the country — are creating a group that intends to address the links between climate change and health risks.

“I view this as one of the largest environmental health crises of our time because of the many pathways in which climate affects us — be it from direct heat effects and heat waves in urban centers, ground-level smog, ozone red alert days, stagnant air masses and warmer temperatures, to some infectious diseases,” said Jonathan Patz, director of the Global Health Institute at the University of Wisconsin, Madison.
