Decades of rigorous research has resulted in an overwhelming scientific consensus about Lyme disease diagnosis and treatment.

The scientific consensus has been affirmed by scientific reviews in the British Medical Journal and the Journal of the American Medical Association, and by medical and scientific groups around the world.

In line with the scientific consensus, in 2020, the Infectious Diseases Society of America, American Academy of Neurology, American College of Rheumatology, representatives from 12 other medical specialties, and patient representatives released comprehensive evidence-based guidelines.

An independent review published in the Journal of the American Medical Association rated the 2020 consensus guidelines as “good” or “good/fair” in all evaluated categories.

Additionally, an independent scientific panel conducted an exhaustive review of the science in 2010. The panel held an all-day public hearing and considered 1,025 references. An independent ombudsman certified each panel member as being free from conflicts of interest.

The independent panel unanimously upheld each of the recommendations made by the Infectious Diseases Society of America (IDSA) in 2006.  Among other things, the panel concluded:

  • In the case of Lyme disease, inherent risks of long-term antibiotic therapy were not justified by clinical benefit.
  • To date, there is no convincing biologic evidence for the existence of symptomatic chronic B. burgdorferi infection among patients after receipt of recommended treatment regimens for Lyme disease.

The American Academy of Pediatrics said it more simply:

“Chronic Lyme disease” is not a medical diagnosis.

As of 2022, six randomized controlled trials and a number of other scientific studies provide strong evidence that Lyme disease patients do not benefit from long term antibiotics.

Those with “chronic Lyme” rarely had real Lyme

The pseudoscientific diagnosis called “chronic Lyme” should not be confused with symptoms stemming from authentic Lyme disease, including Lyme arthritis and post-Lyme symptoms.

The vast majority of people diagnosed with chronic Lyme disease never had Lyme infection in the first place. Therefore, any treatment for presumed Lyme disease would be inappropriate.

According to experts:

There are few better examples of health care fraud than the promotion of so called “chronic Lyme disease.”

Chronic Lyme stories typically exhibit many red flags, such as:

  • diagnosis via pseudoscience practitioner (e.g. “Lyme literate”, functional, integrative, or naturopathic),
  • clinical history and non-specific symptoms inconsistent with Lyme disease,
  • a belief that an infection occurred years earlier,
  • diagnosis in an area where real Lyme is rare or non-existent,
  • multiple fake diagnoses, like alternate-universe versions of Bartonella and Babesia that bear no resemblance to the real infections,
  • testing that is not positive or that uses unproven methodology,
  • use of herbs/supplements
  • outrageous treatment regimens, and
  • others listed on our red flags page.

Scientists from the UK emphasize:

The epidemiology of so-called ‘chronic Lyme’ is more characteristic of a cultural phenomenon than an infectious disease. Public interest in Lyme disease has increased considerably due to ‘celebrity’ cases and discussion on social media.

A disturbing epidemic of false Lyme diagnoses 

False positive Lyme disease diagnoses are very common, as found in a number of studies, including an exhaustive review of 14 years of visits to an infectious diseases clinic of the Johns Hopkins University School of Medicine.

In the Hopkins sample of 1261 patients, at least 72% of patients who visited for concerns about Lyme disease did not have the infection. Nevertheless, 84% of the patients with no Lyme disease received needless antibiotics. A follow-up study on the same sample noted that some patients had complications from the antibiotics, including C. difficile infection and venous thrombosis due to IV administration.

In the Hopkins study, roughly 2/3 of the 1061 patients without active Lyme disease were able to receive other diagnoses. The study found:

Leading diagnoses were anxiety/depression 222 (21%), fibromyalgia 120 (11%), chronic fatigue syndrome 77 (7%), migraine disorder 74 (7%), osteoarthritis 62 (6%), and sleep disorder/apnea 48 (5%).

Examples of less frequent but non-syndromic diseases newly diagnosed included multiple sclerosis (n = 11), malignancy (n = 8), Parkinson’s disease (n = 8), sarcoidosis (n = 4), or amyotrophic lateral sclerosis (n = 4).

Results of 1261 patients who visited Johns Hopkins for presumptive Lyme disease from 2000 to 2013: 72% had no Lyme disease, but 84% of the patients with no Lyme disease received unnecessary antibiotics

ILADS Guidelines: “Potential harms”, “Not evidence-based”

Sadly, a dangerous anti-science group called ILADS has formed whose adherents have promoted all manner of quackery. Long term antibiotics are just one of numerous pseudoscientific and potentially dangerous modalities peddled by grifters associated with ILADS.

Experts have raised alarm about unethical practitioners claiming to be “Lyme literate”, including current or former ILADS leaders.

See more:

For example, ILADS leader Daniel Cameron, MD was disciplined after “allegations included practicing the profession of medicine with negligence on more than one occasion, incompetence on more than one occasion, gross negligence, gross incompetence, and/or failing to maintain accurate patient medical records.” Disturbingly, he was able to keep his medical license.

In addition to quack diagnoses of tick-borne diseases, ILADS leaders have promoted other unrecognized conditions, such as electromagnetic hypersensitivity, “toxic mold illness”/CIRS, and Morgellons.

Tellingly, ILADS admits all twelve of its 2014 recommendations—co-authored by Cameron—are based on “very low-quality evidence”. Infectious disease expert Mark Crislip, MD comments:

  • What do you call a recommendation based on very low quality data? Belief. Belief is what you do in the absence of data.
  • But more than basing their suggestions on low quality data, they ignore the fact that there is data that contradicts their position.

The above-mentioned British Medical Journal review states that the 2014 ILADS recommendations “have not provided any credible clinical or scientific evidence to support prolonged antibiotic therapy. Their designation as ‘evidence based guidelines’ belies their anecdotal nature and lack of coherent and evidence based guidance.”

In 2010, the Healthcare Protection Agency of UK—after noting the vulnerability of patients “desperate for an explanation and possible cure for their illnesses”—issued scathing conclusions about guidelines issued by ILADS:

  • The ILADS guidelines are not evidence-based and are poorly constructed.
  • Application of the ILADS guidelines’ poorly defined case definitions will result in a very high risk of misdiagnosis.
  • Use of ILADS guidelines’ vague treatment recommendations, including prolonged use of antibiotics, has potentially serious consequences.
  • Patients misdiagnosed with Lyme disease risk losing opportunities for diagnosis and treatment of other conditions. They also risk serious physical, psychological social and financial adverse events.

🌍 Experts agree around the world 🌎

Below are medical and science groups that support the scientific consensus about diagnosing and treating Lyme disease:

Other affirmations of support for science-based Lyme disease testing:

Studies show scientific consensus

Connecticut, USA study

A 2010 survey of Connecticut primary care physicians found 98% indicated they neither diagnosed nor treated presumed chronic Lyme disease.

British Study

In 2010, Dr. Sue O’Connell, a microbiologist who headed the Health Protection Agency Lyme Borreliosis Unit in the UK, performed a survey of Lyme diagnosis and treatment guidelines from 16 groups of medical experts in Europe and North America. She noted:

There is overall agreement regarding the clinical features of Lyme borreliosis and on the requirement for supporting laboratory evidence of a clinical diagnosis of later-stage infection. Two-tier serological testing, with immunoblot as a second-stage test, is currently recommended in most guidelines and reviews.

and:

No evidence-based European or North American guideline recommends prolonged or multiple courses of antibiotics for persistent symptoms following previously treated Lyme disease.

French Study

In 2018, a French review of European and American Lyme diagnostic guidelines noted “a global consensus.” This review concluded:

Contrary to the intense debate taking place on the Internet and in the European and American media, our analysis shows that the great majority of medical scientific guidelines with a high quality score, agree on the clinical diagnostic methods of Lyme disease.

Of the 16 guidelines reviewed in 2018 from 7 countries, only the guidelines of the pseudoscience group German Borreliosis Society (Deutsche Borreliose-Gesellschaft, DBG) were an outlier. DBG’s guidelines received the lowest quality score, 1. Similar to its America-based counterpart ILADS but unlike mainstream organizations, DBG recommended non-standard testing and defined a “chronic stage” of Lyme disease.

Presumably ILADS is not in the French review because no published diagnostic guidelines were available.

Independent Report from Washington State

In 2016, the Washington State Medical Quality Assurance Commission produced an independent report on the effects of long-term antibiotic treatment for Lyme disease.

The independent report acknowledged the overwhelming scientific consensus:

Long-term antibiotic treatment of “chronic Lyme disease” – a term the medical community doesn’t find meaningful – is not in patients’ best interest. Most patients with medically unexplained symptoms who received a diagnosis of post-treatment Lyme disease will require more than antibiotics to manage their symptoms. These patients should consult with their physician regarding a treatment plan that also includes emotional support, nutritional guidance and physical therapy. Practitioners should openly address any concerns and should reassure patients. Antibiotics are no substitute for sympathetic listening and explanation.

The benefits associated with long-term antibiotic treatments do not outweigh the risks to the residents of Washington. Evidence-based science has not determined the best long-term treatment option for post-treatment Lyme disease syndrome. Evidence-based treatments should remain the standard in Washington to ensure our residents’ safety.

In Washington State, Lyme disease cases are almost non-existent (generally only 0 to 3 endemic cases per year) and greatly outnumbered by fictional cases.

Sources to avoid because they deny the scientific consensus

The harmful chronic Lyme movement started in the late 1980s and was described as a cult in a 2001 New York Times story. Allen Steere, one of the discoverers of Lyme disease, was being stalked and harassed by Lyme conspiracy theorists:

Early on, he tried to explain why, based on the science, he didn’t believe many of them had Lyme disease and, even if they did, why long-term antibiotics might not help. But none of it seemed to matter. On the Web, in virtual worlds Steere did not know or understand, patients who believed they had the paralyzing illness vilified him. Egged on by advocacy groups, they infected his sterile world, trying to destroy his reputation and career.

Much like Scientology, this movement was anti-psychiatry:

Because of the stigma of mental illness as well as the lack of cures for other diseases like fibromyalgia or chronic fatigue, they say, there is a constellation of forces pushing for such a diagnosis. Many companies often will not help mentally ill employees or those with poorly understood disorders like fibromyalgia; worse, insurance companies still don’t want to pay for long-term psychiatric care. As a result, they say, there is now a movement to treat other illnesses — including chronic fatigue syndrome and fibromyalgia — as Lyme disease and to attack doctors when they don’t.

Says one doctor in Steere’s camp: ”There is now a cult out there — these advocacy groups — that says to people: ‘This is not depression. This is not your fault. You have a spirochete in the brain. You should sue your doctor. What’s more, we’ll be your expert witness.”’

Steere puts it more philosophically. ”We’ve come to have the idea in America that it is possible to cure anything and that everyone could be well, and it’s even their right to be well, and they should be angry if the medical profession doesn’t make you well.”

A 1991 article in Harvard Health Letter reported on the “Lymeys” in a manner that still fits today:

Lymeys are unified by their belief that infection with the Lyme agent is the cause of their symptoms and by a general mistrust of standard medicine and its limitations. Many of them shun treatment at major medical centers known for research on Lyme disease. Instead, following what they read in the newsletters, some Lymeys travel great distances to consult self-appointed specialists with dubious credentials.

These doctors often prescribe intravenous antibiotic regimens lasting for months or, in extreme cases, years, at a cost of literally hundreds of thousands of dollars. Acting on physicians’ orders, private companies will administer intravenous drugs in patients’ homes. Some of these companies advertise their services in Lymey newsletters, help pay the publications’ costs, and publicize support groups.

Decades later, the bizarre beliefs of the “Lymeys” have been disproven over and over. Nevertheless, the chronic Lyme movement has supersized thanks to the internet, social media, celebrities, the wealthy, politicians, and quacks.

A 2004 study of web sites about Lyme disease revealed many that promoted inaccurate information. Web sites with information determined to be inaccurate tended to have the word “Lyme” in their names and included LymeDisease.org, IgeneX, ILADS, and Lyme Disease Association.

Sadly, the epidemic of misinformation about Lyme disease has only grown since 2004.

In 2017, March for Science had to cut ties with a pseudoscience group that falsely claimed to be representative of Lyme patients.

In 2018, scientists in the Department of Dermatology at Johns Hopkins University reported that sites such as Lymedisease.org are spreading inaccurate information about Bartonella, which is not a known tick-borne disease in North America or coinfection of Lyme disease.

Unfortunately, substantial confusion is caused by pseudoscience being legitimized in academia, almost entirely by initiatives funded by wealthy conspiracy theorists.

The easiest way to determine if an entity is dedicated to dangerous chronic Lyme pseudoscience is if it refers patients to predatory “Lyme literate” doctors or other practitioners of unscientific medicine (see below).

Follow the money

As of 2024, over $100 million has been pumped into promoting chronic Lyme pseudoscience, including funding universities and researchers who undermine long-settled science and are inclined to violate basic standards of ethics. An example is ILADS leader Leona Gilbert, who was found guilty of scientific misconduct along with her business partner Kunal Garg.

In one of the more appalling scandals, US government employees dedicated taxpayer-funded resources to pump out anti-science and anti-patient propaganda and accepted millions of dollars from crank billionaires Steven and Alexandra Cohen. Additionally, Cohen-funded scientists appeared in the Cohen-produced conspiracy theorist documentary The Quiet Epidemic, which exploited an abused teenager.
