Lyme disease is a bacterial infection caused by the spirochaete Borrelia burgdorferi. It occurs worldwide, is increasing in incidence and is the most common tick-borne disease in the northern hemisphere. Whilst early recognition and treatment lead to resolution of the illness for many patients, late or missed diagnosis may result in persistent, debilitating symptoms.

Lyme disease symptoms may be non-specific and difficult to recognise. Raising awareness amongst primary care clinicians will increase the likelihood of patients receiving early and effective treatment. Clinicians should be aware of the genuine scientific uncertainties and ongoing research in relation to both diagnosis and treatment of this disease.

This toolkit is a user-friendly guide to Lyme disease for general practitioners and other healthcare professionals. Patients and the public may also find it helpful.
