Recurrence or Relapse of <scp>COVID</scp> ‐19 in Older Patients: A Description of Three Cases
Bibliographic record
Abstract
BACKGROUND: COVID-19 has infected millions of people worldwide, particularly in older adults. The first cases of possible reinfection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were reported in April 2020 among older adults. DESIGN/SETTING: In this brief report, we present three geriatric cases with two episodes of SARS-CoV-2 infection separated by a symptom-free interval. PARTICIPANTS: The participants of this brief report are three cases of hospitalized geriatric women. MEASUREMENTS/RESULTS: We note clinical and biological worsening during the second episode of COVID-19 for all three patients. Also, there is a radiological aggravation. The second episode of COVID-19 was fatal in all three cases. CONCLUSION: This series of three geriatric cases with COVID-19 diagnosed two times apart for several weeks questions the possibility of reinfection with SARS-CoV-2. It raises questions in clinical practice about the value of testing for SARS-CoV-2 infection again in the event of symptomatic reoccurrence. J Am Geriatr Soc 68:2179-2183, 2020.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
