Editorial correction — October 10, 2026: This historical video post has been corrected against the primary paper. Its earlier Lyme and specimen-percentage claims were inaccurate. The videos below remain as historical advocacy material; their inclusion is not verification of every claim they contain.
The CDC-led investigation included people reporting fibers or other materials with skin lesions or disturbing skin sensations, and it examined collected specimens. Its findings should be described using the original study rather than the interpretations in an advocacy video.
For the non-biopsy material collection, investigators examined 23 specimens from 12 participants. Protein, likely superficial skin, was reported in 83% of specimens and cellulose consistent with cotton in 43%. These categories overlapped. The percentages describe specimens, not patients, and do not demonstrate abnormal keratin or collagen filament production.
The paper reports one positive and one borderline Lyme enzyme immunoassay result, with no positive IgG Western blots. The earlier statement that all 12 patients had Lyme evidence was incorrect: 12 refers to the non-biopsy specimen-collection subgroup. A later Borrelia study investigated a different group of 25 patients.
The original CDC-led paper identified no common infectious source and described similarities to delusional infestation. It also could not determine whether the presentation was a new condition or wider recognition of an existing one. These findings do not constitute a psychiatric diagnosis for every person reporting similar symptoms. See our current analysis of the CDC study for context and limitations.
The original advocacy video honoring study participants is preserved below.
The following historical presentation discusses the CDC study. Compare its interpretations with the primary paper and the corrections above.
These additional presentations are retained as part of this post’s historical record.
This final historical presentation offers an advocate’s interpretation of the research; readers should evaluate its claims against the original sources.
