...says the title of the article at the above url. And although I can see/understand the potential for increased risk I can't help but think the headline overstates the 'problem.'
The article states that the white-footed mouse is the preferred host of the black-legged tick (see...integration is natural...). Infected by the ticks, the mice are described as being a very effective vector of the disease. Acorns are important to the mice and, supposedly, acorn production crashed this past year. This will lead to a smaller population of the mice. "This spring, there will be a lot of...infected black-legged ticks...looking for a blood meal. And instead of finding a white-footed mouse, they are going to find other mammals—like us." (emphasis mine).
That all sounds logical but the tick's leap from mice to humans sounds like a stretch to me. More ticks (and more humans) can easily lead to more Lyme disease but the article seems to say it's a given that the ticks will make the transition to humans. The mice population crashes because of the lack of acorns but nothing is said about the potential crash of the tick population because of the lack of mice.
There's a risk in popular press (mis)reporting of scientific findings just as there's a risk in readers' interpretations (guilty as charged). Still, be careful out there.
