Through 2026
Read the papers the way they were written, not the way the internet summarized them.
Public-health pages and a smaller laboratory line have spent twenty years talking past each other. Below, each item is dated, claimed, and limited. Nothing here is a prescription.

Morgellons disease: analysis of a population with clinically confirmed microscopic subcutaneous fibers of unknown etiology
Savely VR, Stricker RB · Clinical, Cosmetic and Investigational Dermatology
Claims. Described a clinic population with fibers visible under unbroken skin, female predominance, and frequent co-occurrence with Lyme-like illness.
Limits. Observational clinic series, not a controlled population study. Does not by itself prove cause.
- 2012January 25, 2012Public-health / clinic consensus
Clinical, epidemiologic, histopathologic and molecular features of an unexplained dermopathy
Pearson ML, Selby JV, Katz KA, et al. (CDC / Kaiser Permanente Northern California / AFIP) · PLOS ONE
Claims. Among 115 Northern California cases, prevalence was about 3.65 per 100,000. Median age 52; 77% women. No shared infectious source was identified in the tests used. Most collected fibers were consistent with cotton. Quality of life was markedly reduced. The authors wrote the presentation was similar to more commonly recognized conditions such as delusional infestation, and that they could not say whether this was a new condition or wider recognition of an existing one.
Limits. A limited descriptive study in one health system. Lyme search used serology, not culture or immunohistochemistry. Later summaries sometimes harden this paper into a psychiatric verdict it did not formally issue.

History of Morgellons disease: from delusion to definition
Middelveen MJ, Fesler MC, Stricker RB · Clinical, Cosmetic and Investigational Dermatology (PMC)
Claims. Argues that filaments are human cellular products (keratin, collagen) rather than clothing lint, and reports detection of Borrelia DNA in specimens by multiple laboratories. Compares the presentation to bovine digital dermatitis, a treponemal disease of cattle.
Limits. Review plus prior laboratory work from a small group of investigators. Independent replication at scale remains limited.

Delusional parasitosis (patient education)
Mayo Clinic Staff · Mayo Clinic
Claims. Treats Morgellons as a form of delusional parasitosis. Cites the 2012 CDC study: no infection or parasites found; fibers often explained by fabric and repeated scratching.
Limits. A clinical overview, not new primary research. Reflects the dominant dermatology/psychiatry consensus.
- 2025June 24, 2025Methods review
Morgellons disease: a review on current evidence and the need for consensus, standardized criteria, and future randomized controlled trials
Archives of Dermatological Research review authors · Archives of Dermatological Research, vol. 317, article 815
Claims. After screening 167 papers, found no randomized trials of Morgellons treatments. Calls for an expert group to write diagnostic criteria, then observational studies, then RCTs. Notes that neuroimaging work exists for delusional infestation, not a shared biomarker framework for Morgellons.
Limits. A methods-and-gap review. It does not settle cause.
- 2025November 2025Laboratory / Lyme-associated line
OSU Center for the Investigation of Morgellons — ILADS 2025 poster
Samantha Rice, under Randy Wymore, Oklahoma State University CHS · ILADS Annual Conference, San Antonio (reported by CEHF)
Claims. Reported genetic sequencing consistent with earlier work, and associated organisms including Borrelia species, Helicobacter pylori, Bartonella henselae, and Treponema denticola. OSU and CEHF treat Borrelia as the primary infectious candidate.
Limits. Conference poster, not a completed peer-reviewed trial. Association is not the same as proven causation in every patient.
- 2026February 11, 2026Public-health / clinic consensus
Morgellons disease (patient education)
Cleveland Clinic · Cleveland Clinic Health Library
Claims. Describes crawling, burning, biting, and visible fibers. States fibers are usually skin proteins, hair, or tiny materials made visible by irritation — not parasites. Frames the condition as a signaling disconnect between brain and skin. Care may include medicines that dampen skin sensations and cognitive behavioral therapy.
Limits. Consensus patient page. Does not review the 2025–2026 laboratory papers in depth.
- 2026April 16, 2026Preprint — not peer-reviewed
Metagenomics reveals a phylogenetically informed microbial signature associated with Morgellons disease
bioRxiv preprint authors · bioRxiv preprint
Claims. Deep sequencing of lesions versus unaffected skin in a five-person family cohort found sequences poorly represented in existing databases and a microbial signature that differed from nearby healthy skin.
Limits. Preprint. Tiny, related cohort. Motivates more work; does not establish a single pathogen or a public-health diagnosis.

The cellular origin of Morgellons disease fibers: a twenty year odyssey
Middelveen MJ, Fesler MC, Stricker RB · Archives of Clinical and Biomedical Research 10(4):224–236
Claims. Traces twenty years of fiber work. Reports fibers as keratin and collagen from keratinocytes and fibroblasts, sometimes small human hairs; autofluorescence under UV; unusual melanin; bacterial antigens and amyloid in some fibers. Frames the illness as infection-related, often tied to Borrelia.
Limits. A long-arc review plus unpublished observations from one research line. Needs broader independent replication and agreed diagnostic criteria (the 2025 dermatology review’s point).
What still is not known
- A shared, agreed diagnostic definition across clinics.
- A randomized trial of any treatment aimed at Morgellons as such.
- Whether keratin/collagen filaments, cotton contamination, and “nothing under the skin” describe different people, different moments, or the same sores seen by different methods.
- How often tick-borne infection is necessary, sufficient, or coincidental.
