Abstract
Introduction: The human population has faced several pandemics throughout history, with the most recent being COVID-19. Studies on COVID-19 in Brazil, in general, have primarily focused on the country as a whole or on large urban centers. However, prevention measures should also consider smaller municipalities, as the disease has significantly affected these areas as well. Objective: To evaluate the geospatial distribution and risk factors associated with SARS-CoV-2 infection in residents of a low-population-density municipality in the state of Minas Gerais, Brazil. Material and Methods: This retrospective cross-sectional study collected data from COVID-19 notification forms recorded by the Municipal Health Surveillance in Santos Dumont, Minas Gerais, Brazil, from March 2020 to July 2021. Variables associated with SARS-CoV-2 infections were evaluated using explanatory univariate and multivariate logistic regression models. The occurrence of possible spatial clusters among the reported COVID-19 cases in the municipality was assessed using Kernel Density Estimation (KDE) and Spatial Scan analyses. The main variables explored as explanatory for SARS-CoV-2 infections were race/ethnicity, gender, and health-related occupations. Results: Out of 8,271 individuals with suspected COVID-19 in Santos Dumont, 55% (4,595) declared themselves as residents of the municipality. Among these, 4,093 had complete records for spatial analysis, with 1,274 (31%) testing positive for SARS-CoV-2. The choropleth map revealed that infections were concentrated in the central region of the municipality. Univariate analysis showed no statistically significant differences in infection rates based on gender or race/color. However, multivariate analysis indicated that non-health professionals had a significantly higher risk of SARS-CoV-2 infection (OR 2.042; 95% CI 1.41-2.94). Conclusion: The central, denser area of the municipality was more susceptible to SARS-CoV-2 transmission. Additionally, non-health professionals faced higher risks of infection. These findings can serve as tools for the development of public health policies to control future pandemics.

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
