“In seven studies conducted in endemic areas, comprising a total of 1902 patients referred for suspected Lyme disease, only 7–31% had active Lyme disease and 5–20% had previous Lyme disease. Among the remainder, 50–88% had no evidence of ever having had Lyme disease.”

So what is causing the symptoms of “chronic Lyme” patients?
The CDC and NIH emphasize that experts do not support the use of the term “chronic Lyme disease” because of confusion. Writing in the New England Journal of Medicine, 31 doctors and scientists classified those with the chronic Lyme label into four predominant groups:
- Category 1: Symptoms of unknown cause, with no evidence of Borrelia burgdorferi infection
- Category 2: A well-defined illness unrelated to B. burgdorferi infection
- Category 3: Symptoms of unknown cause, with antibodies against B. burgdorferi but no history of objective clinical findings that are consistent with Lyme disease
- Category 4: Post–Lyme disease syndrome
Feder et al observed “Only patients with category 4 disease have post–Lyme disease symptoms.” Looking at references 31-33 below, Feder et al stated:
Data from studies of patients who underwent reevaluation at academic medical centers suggest that the majority of patients presumed to have chronic Lyme disease have category 1 or 2 disease.
In other words, evidence indicates that the symptoms of most “chronic Lyme” patients were clearly not caused by Lyme disease. In addition, most “chronic Lyme” stories contain a number of red flags of quackery, including multiple false diagnoses.

Untreated Late Lyme Disease
In the United States, the typical manifestation of Lyme disease that is untreated for months or longer involves Lyme arthritis. In this stage, antibody tests are expected to be positive.

According to Steere and Arvikar:
Patients with Lyme arthritis have intermittent or persistent attacks of joint swelling and pain in one or a few large joints, especially the knee, usually over a period of several years, without prominent systemic manifestations.
In Europe, a skin manifestation called acrodermatitis chronica atrophicans can occur in late stage Lyme infection.
