Abstract
Chronic hepatitis B virus (HBV) infection poses significant public health challenges in Canada, particularly among newcomers from regions with high HBV prevalence. In alignment with the World Health Organization’s goal of HBV elimination by 2030, this 2025 guidelines update—developed jointly by the Canadian Association for the Study of the Liver (CASL) and the Association of Medical Microbiology and Infectious Disease (AMMI) Canada—presents recommendations for universal adult HBV screening, vaccination, laboratory assessment, and treatment. These guidelines emphasize patient-centred care, early diagnosis, and expanded antiviral treatment, including for individuals in the indeterminate or grey zone and special populations such as pregnant individuals, children, and those coinfected with HIV, hepatitis C, or hepatitis D. Notably, the guidelines recommend reflex HDV testing and routine use of quantitative HBsAg to support management decisions. These evidence-based recommendations are informed by expert consensus, recent literature, and international standards, with the aim of improving outcomes, reducing stigma, and informing future policy and research priorities.

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
