Abstract
We report on a three year-old male who contracted enteric fever during a visit to the Sindh province of Pakistan in the summer of 2018. He was diagnosed after returning to Canada and blood cultures isolated Salmonella enterica serovar Typhi which harbored extensive drug-resistance (XDR) to all first-line antibiotics including ceftriaxone. Empiric ceftriaxone was switched to meropenem and he was successfully treated with a two-week course. An outbreak of XDR typhoid is currently emerging from Pakistan and several outbreak-related cases have been identified in the U.K and U.S. Whole genome sequencing confirmed that our child was infected with the XDR outbreak-strain. Current empiric antimicrobial choices will result in treatment failure if an XDR strain is encountered, therefore clinicians must adapt their empiric approach for those returning from high risk regions. This is the first XDR typhoid case in Canada and the first pediatric case to be diagnosed and treated outside of Pakistan. Clinicians must be vigilant of future cases.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
