Yesterday we released “The Persistent Dozen.”

It includes 12 papers on SARS-CoV-2 persistence. There are 100s & we are currently sorting through them, but here are 12 interesting ones.

There is no doubt, SC2 & spike protein persist.

- SARS-CoV-2 (SC2) Found 45% Of The Time In Plasma Of Those With Persistent Symptoms After Acute SC2

pmc.ncbi.nlm.nih.gov/articles/PMC88…

11. Persistence of spike protein at the skull-meninges-brain axis …

Keys:

- SC2 Spike P Persists In The Skull-Meninges-Brain Axis In COVID-19 Patients

- Spike Protein Is Sufficient To Induce Brain Pathological & Behavioral Changes In Mice

These are 12 of 100s of papers that show, or discuss, SARS-CoV-2 viral persistence, spike protein persistence, or SC2 particle persistence.

There is absolutely no doubt, SARS-CoV-2 persists & those with Long COVID face unique issues that can’t be dealt with via conflation.

3/16/25 is the last day of Long Covid Awareness week, so …

let’s never forget that SARS-CoV-2 persists when demanding better testing, trials, & treatments.

Cure Long COVID!
