A Lyme disease rash may be a symptom of Lyme disease. About 50% of people bitten by a deer tick develop an erythem migrans (EM) rash at the bite site. A classic bull’s eye rash with a central clearing is a type of an EM rash, and only about 9% develop that classic bull’s eye, other EM rashes look different. Some of those who are bitten by a tick do not develop any rash. Rashes at other than a bite site means disseminated diseases.
The Lyme Disease Association gave a grant to Columbia University to develop and distribute a poster to physicians. With Columbia’s permission, we have made the poster available here for anyone to print and distribute. It must be printed in its entirety.
