I HATE ticks (continued)

Lyme Disease predicted to surge this year in Northeast US

The correct way to remove a tick

EDITOR'S NOTE: Ticks are already very active in Charlestown. Each time I do yard work, I find a couple. Rhode Island has a remarkable in-state resource at URI. They run a very informative (and very lively) website that is well worth checking out for its great educational content, practical tips and entertainment value. Click here.)

Lyme disease is becoming more common in the Northeastern US, and is spreading more broadly across the eastern US. Commonly thought to be spread by Whitetail deer since it is carried by deer ticks, it is actually carried as well by field mice, chipmunks, and other small mammals.

A new study suggests that the northeastern U.S. should prepare for a surge in Lyme disease this spring. And we can blame fluctuations in acorns and mouse populations, not the mild winter. So reports Dr. Richard S. Ostfeld, a disease ecologist at the Cary Institute of Ecosystem Studies in Millbrook, NY.

This is what a really bad tick bite looks like, but it
doesn't have to be this bad to warrant a doctor's attention

What do acorns have to do with illness? Acorn crops vary from year-to-year, with boom-and-bust cycles influencing the winter survival and breeding success of white-footed mice. These small mammals pack a one-two punch: they are preferred hosts for black-legged ticks and they are very effective at transmitting Borrelia burgdorferi, the bacterium that causes Lyme disease.

"We had a boom in acorns, followed by a boom in mice. And now, on the heels of one of the smallest acorn crops we've ever seen, the mouse population is crashing," Ostfeld explains. Adding, "This spring, there will be a lot of Borrelia burgdorferi-infected black-legged ticks in our forests looking for a blood meal. And instead of finding a white-footed mouse, they are going to find other mammals—like us."

For more than two decades, Ostfeld, Cary Institute forest ecologist Dr. Charles D. Canham, and their research team have been investigating connections among acorn abundance, white-footed mice, black-legged ticks, and Lyme disease. In 2010, acorn crops were the heaviest recorded at their Millbrook-based research site. And in 2011, mouse populations followed suit, peaking in the summer months. The scarcity of acorns in the fall of 2011 set up a perfect storm for human Lyme disease risk.
