Diagnosing and Managing Early Lyme Disease in Ontario

Public Health Ontario Grand Rounds

As Ontario continues to see a rise in the incidence of Lyme disease and an increase of ticks, there is a need for health care providers and the public health community to be aware of the most current evidence when working with patients.

Health Quality Ontario (HQO) released a clinical guidance document to assist health care providers when considering the diagnosis and management of Lyme disease in its early stage. This presentation demonstrates how to use the guidance document and provides an updated summary on Lyme disease epidemiology and testing in Ontario.
