It’s like Lyme disease and has recently been spotted in the Northeastern United States, as well as in a few parts of the Upper Midwest.
The bacteria that causes this new disease is called Borrelia miyamotoi, and, like Lyme, it hitches a ride in ticks. It can cause something like the flu, or a fever that just keeps coming back. Scientists first identified it in Japan. But a couple of years ago, Yale researchers discovered it in deer ticks in New England.
