Lyme Disease (and Other Tick-borne Diseases)—Child Care and Schools

An infection caused by a type of bacteria, known as spirochetes, that is transmitted when particular types of ticks attach to a person’s skin and feed on that person’s blood. These ticks are very small, only a few millimeters (about the size of a freckle); the ticks that transit Lyme disease are found mainly in the Northeast and Midwest and on the West Coast.
