Epidemiology of GB virus type C among patients infected with HIV in Singapore
Bibliographic record
Abstract
Several studies have shown that individuals co-infected with GB virus type C (GBV-C), and human immunodeficiency virus (HIV) have slower progression to acquired immunodeficiency syndrome (AIDS) and a prolonged lifespan, compared to those infected with only HIV. In Singapore, despite the steadily increasing number of HIV infections in recent years, there are no studies documenting the extent of GBV-C/HIV co-infection in this group of patients. To fill this dearth of information, two GBV-C screening assays was performed on 80 archived HIV-1-positive samples from the National University Hospital. The overall prevalence of GBV-C co-infection among patients infected with HIV in this study was 10% (8/80). Phylogenetic analysis of the eight dual-infection cases revealed that genotypes 3 (4/8, 50%) and 2a (2/8, 25%) were the main genotypes circulating among these Singaporean HIV patients. One case each of genotypes 2b (1/8, 12.5%) and 4 (1/8, 12.5%), which have not been described previously in Singapore, were identified. These findings hint at the complex epidemiology of GBV-C in different patient groups and a larger study would be needed to characterize, and understand the potential clinical impact of GBV-C co-infection on the patients.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
