Reviewer: Marcia Firmani, PhD, MSPH, MT(ASCP)

Tickborne infections are the most important of vectorborne diseases in the United States (US). Because tickborne diseases are so difficult to diagnose, deaths and morbidity occur. This course will review the life cycle, geographical ranges, and identification of ticks involved in human diseases. The organisms that cause tickborne diseases will be discussed, to include Lyme disease, Rocky Mountain spotted fever, human monotropic ehrlichiosis and granulotropic anaplasmosis, tularemia, babesiosis, southern tick-associated rash illness, tickborne relapsing fever, Colorado tick fever, and other rare and emerging tickborne diseases. Numerous case studies about tickborne diseases are also presented.
