Whether acting in the capacity of primary care provider, advocate or educator, nurses can take an active role in the prevention and control of Lyme disease. To do this effectively, nurses need to understand issues related to the diagnosis, treatment and prevention of Lyme disease. Nurse's ability to recognize the signs and symptoms of Lyme disease can have a significant impact on the chronic morbidities associated with this illness. Likewise, nurses' ability to educate patients about Lyme disease may be one of the best tools available to prevent exposure to this illness. The purpose of this continuing education program is to provide nurses with the information they need to take on these roles with confidence.
