Lyle Petersen, director of the Division of Vector-Borne Diseases at the CDC's National Center for Emerging and Zoonotic Infections Diseases, said "The data show that we're seeing a steady increase and spread of tick-borne diseases, and an accelerating trend of mosquito-borne diseases introduced from other parts of the world," John Tomasic reports for Route Fifty.
In addition to the diseases they cause, bites from the lone star tick can trigger something weirder: an allergy to beef and pork, Zoya Teirstein reports for Grist. Because of global warming, the once-scarce tick has expanded its range to most of the eastern half of the U.S. Lone star ticks thrive in warm, humid environments, and with fewer days below freezing, they're able to stay active longer and breed more. Reforestation efforts may also contribute to the lone star tick's resurgence: they love to hitchhike on white-tailed deer, which are coming back because they have more room to roam.
