Last spring, the Environmental Protection Agency (EPA), named Lyme disease as one of the indicators of climate change. That’s because the range of the black-legged tick, which carries the bacteria that causes Lyme disease, is growing. Factors such as suburban sprawl and warmer temperatures are causing the ticks to spread across the country. Even though Lyme disease was only discovered 40 years ago, cases have doubled since the 1990s, while the number of counties at high risk has more than tripled.
