Abstract

fetched live from OpenAlex

Background/Objectives: We aimed to examine the relationship between COVID-19 cases and Public Health Interventions (PHIs), vaccine coverage, and temperature. We compared our findings with those of other studies that used different methodologies, such as mathematical models. Methods: We developed monthly PHI scores using the Oxford COVID-19 Government Response Tracker from May 2020 to May 2021. We calculated PHI scores by summing the highest monthly score of each intervention and expressed the PHI score as a percentage of the maximum. We obtained vaccine coverage and temperature data from January 2021 to September 2023. We calculated Spearman’s rank-order correlation coefficients to examine correlations. Results: The correlation between cases and PHI was positive (ρ = 0.947, p < 0.0001). The correlation between cases and vaccine coverage was approximately zero (ρ = 0.0165, p = 0.957) from January 2021 to January 2022 and was negative from February 2022 to September 2023 (ρ= −0.816, p < 0.0001). The correlation for cases and temperature was negative from January 2021 to January 2022 (ρ = −0.676, p = 0.0112) and was almost zero from February 2022 to September 2023 (ρ = −0.162, p = 0.494). The models showed a negative correlation between PHI and vaccine coverage, and mixed results for temperature. Conclusions: There was a positive correlation between cases and PHI. Prior to reaching the vaccine threshold coverage, there was no correlation for vaccination and a negative correlation for temperature. Post-vaccine threshold, there was a negative correlation for vaccination and no correlation for temperature. Correlation results for PHI and temperature differed from those of the mathematical models.

Teacher imitation

Not 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.
