Expansion of the <i>Plasmodium falciparum Kelch13</i> R622I Mutation in Northwest Ethiopia
Bibliographic record
Abstract
Abstract According to the World Health Organization, almost two-thirds of the Ethiopian population is at risk of contracting malaria, where infection with Plasmodium falciparum accounts for approximately 60% of cases today. The risk of artemisinin resistance spreading from southeast Asia to Africa is a major concern. We conducted a 28-day in vivo efficacy trial of artemether-lumefantrine (Coartem) for treatment of uncomplicated malaria (n = 97) in the Gondar area, northwest Ethiopia, from 2017 to 2018. Our results confirmed 100% adequate clinical and parasitologic response, with no parasites observed at day 3 by microscopy. Further analysis of day 0 samples showed the expansion of a Kelch13 mutation R622I to 9.5% from 2.4% of isolates reported 3 years earlier. Closer examination of the R622I mutation in vitro is warranted.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
