Clinical presentation of Enterovirus D68 in adults with acute respiratory infections consulting in emergency departments in Quebec, Canada
Bibliographic record
Abstract
Objectives: Enterovirus D68 (EV-D68) is mainly studied in children, while data in adults are limited. We described the clinical presentation of EV-D68 in adults, compared with other enterovirus/rhinovirus (EV/RV) infections. Methods: We used clinical and laboratory data from 1143 adults visiting four emergency departments in Quebec, Canada, for acute respiratory infections (February 2022 to March 2023). We analyzed nasopharyngeal swabs using a multiplex polymerase chain reaction; positive EV/RV samples were further tested with EV-D68-specific polymerase chain reaction assays. We calculated the Pandemic Medical Early Warning Score (PMEWS) to assess severity. Results: = 0.02) and tended to have more underlying chronic respiratory diseases (26% vs 20%) and respiratory symptoms (e.g., dyspnea: 84% vs 75%; wheezing: 63% vs 44%; and chest pain: 63% vs 49%), although these differences were not statistically significant. PMEWS, hospitalizations, and median time spent in the emergency department did not differ significantly between the EV-D68 and the other EV/RV group. Conclusions: Respiratory symptoms tended to be more common among participants with EV-D68 than those with other EV/RV, although disease severity was similar. Larger studies are needed to better characterize EV-D68 infections in adults.

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.
