In 2019, the Association of Medical Microbiology and Infectious Disease (AMMI) Canada reaffirmed both its support for patients and the overwhelming international scientific consensus in a new “Position Statement on the Diagnosis and Treatment of People with Persistent Symptoms That Have Been Attributed to Lyme Disease.”
According to Dr. Todd Hatchette, President of AMMI Canada:
Patients being told they have chronic infection are often given prolonged antibiotics and alternative therapies that have never been shown to work and have, in fact, been harmful.
Patients are suffering from very real and sometimes debilitating symptoms. Unfortunately, there has been a lot of misinformation about Lyme disease. Patients want and deserve honest answers. As Canada’s experts in infectious diseases, we have an obligation to provide answers.
The Position Statement is endorsed by five additional medical groups:
- Association des Medecins Microbiologistes Infectiologues du Quebec
- Canadian Association for Clinical Microbiology and Infectious Diseases
- Canadian Neurological Society
- Canadian Paediatric Society
- Public Health Physicians of Canada
Among other things, AMMI Canada emphasized:
- Patients should be treated in a compassionate, comprehensive, and evidence-guided manner.
- Prolonged antibiotic therapy does not alter patient outcomes, but can lead to potentially severe adverse reactions, like C. difficile and infections arising from intravenous catheters.
- An independent panel, certified free of conflicts of interests, confirmed in 2010 that the IDSA 2006 recommendations were sound.
- FDA and Health Canada approved tests are accurate in late Lyme disease.
- Laboratories that use alternative tests or read tests differently than mainstream doctors can have false positive rates of greater than 50%.
- Patients with chronic symptoms and a negative test for Lyme disease in Canada should not go to the United States to be diagnosed and treated for Lyme disease.
- More research is needed to help patients with ongoing symptoms.
- More education on Lyme disease is needed for health care workers and the public.
In 2020, AMMI Canada endorsed the comprehensive evidence-based Lyme disease guidelines from the Infectious Diseases Society of America (IDSA), American Academy of Neurology (AAN), and American College of Rheumatology (ACR).
The Canadian Medical Association Journal (CMAJ) has also written about how the “chronic Lyme industry” spreads myths that are causing unnecessary concern.
Other medical and science groups in Canada also acknowledge the scientific consensus, including:

- Public Health Agency of Canada
