Don't ‘pooh-pooh’ stool cultures for surveillance of acute flaccid paralysis
Bibliographic record
Abstract
With the continuing risk of poliovirus importation into Canada, active surveillance of acute flaccid paralysis (AFP) in children younger than 15 years of age for potential cases of paralytic poliomyelitis continues to be the focus of surveillance activities. The single most important laboratory investigation to confirm or rule out a diagnosis of paralytic poliomyelitis, which is recommended by the national Working Group on Polio Eradication, is a stool specimen collected within two weeks of the onset of paralysis for isolation of wild or vaccine strains of poliovirus. In 1999, stool specimens were taken for 25 (40.9%) of 61 confirmed cases. Sixteen of the 25 cases were reported as negative for the poliovirus and other enteroviruses; however, laboratory results were unknown for nine cases. The 1999 rate remains significantly lower than the World Health Organization's target of an adequate stool investigation in 80% of AFP cases. A protocol for the investigation of AFP and suspected cases of paralytic poliomyelitis has been published (1) and may be accessed electronically via the Internet at http://www.hc-sc.

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.
