Abstract

fetched live from OpenAlex

People who are incarcerated (PWAI) and correctional staff face a higher risk of communicable diseases. This study assessed the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and sexually transmitted bloodborne infections (STBBIs) in British Columbia (BC) Provincial Correctional Centres (PCCs). A multicentre cross-sectional serosurvey was conducted from January 4 to February 14, 2021, among PWAI and staff. Antibody and molecular screening assessed pathogen prevalence, with Pearson’s chi-squared tests for group comparisons. Mixed-effects logistic regression explored clinical and sociodemographic factors associated with SARS-CoV-2 or STBBIs. Among PWAI (n=299), seroprevalence was 5.5% for SARS-CoV-2, 14.6% for hepatitis C virus, and 1.3% for syphilis. Among staff (n=505), seroprevalence was 2.9% for SARS-CoV-2, 1.7% for hepatitis B virus, and 0.6% for syphilis. Among PWAI, lower education (adjusted odds ratio [aOR]=2.38, 95% confidence interval [CI]: 1.02-5.56), unstable employment (aOR=2.86, 95% CI: 1.16-6.67), and opioid use (aOR=3.56, 95% CI: 1.15-12.65) were associated with STBBI acquisition. Among staff, working in a PCC with a SARS-CoV-2 outbreak was associated with infection acquisition (aOR=7.97, 95% CI: 2.28-27.97). The ongoing presence of SARS-CoV-2 and STBBIs in correctional facilities highlights the need for balanced public health interventions addressing both transmissions, ensuring timely prevention, testing, and treatment for all individuals.

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.
