Abstract
The importation of drug-resistant malaria is a growing public health problem in non-endemic countries. The combination of atovaquone and proguanil (Malarone) has become established as an agent of choice to prevent and treat chloroquine-resistant Plasmodium falciparum malaria in travelers. We describe the first reported case in North America of genetically confirmed atovaquone/proguanil-resistant P. falciparum malaria. Polymerase chain reaction and sequence analysis of the primary and recrudescent isolates confirmed the acquisition of a point mutation (Tyr268Ser) in the cytochrome b gene of the recrudescent isolate known to confer high-level resistance to atovaquone. Suboptimal therapy may have played a contributory role in the emergence of resistance.

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
