Abstract
We provide ongoing HIV and Hepatitis B surveillance in residential First Nations alcohol and drug treatment centres in British Columbia, Canada. All clients enter-ing the centres are offered confidential viral testing as part of an education pro-gram on sexually transmitted diseases. Participation is voluntary and approxi-mately two thirds of clients choose to be tested. Information about risk factors for communicable disease and immunization status is not recorded. The testing pro-gram began in January 1992. As of September 2000, 2,345 people have been tested for HIV. Nine tested positive, giving a prevalence of 3.8 per 1,000 (95 % confi-dence interval: 1.3 to 6.3 per 1,000), lower than among all British Columbians who choose to be tested (8.5 per 1,000). Also, 2,166 people were tested for hepatitis B surface antibody, 23 % of these were positive, 10 % were positive for hepatitis B core antibody (indicating prior infection with hepatitis B). Seven clients (3.2 per 1,000; 95 % CI: 0.8 to 5.6 per 1,000) were positive for hepatitis B surface antigen and are therefore presumed to be chronically infected. The prevalence of hepatitis B markers was intermediate between what has previously been found in high risk groups and that found in the general population. (Int J Circumpolar Health 2002; 61;

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
