The Indian Ocean paradox revisited: HIV and sexually transmitted infections in the Comoros
Bibliographic record
Abstract
The combination of high sexually transmitted infection (STI) prevalence and low HIV prevalence has been described as the Indian Ocean paradox. To investigate current epidemiology of HIV and STI in the Comoros, we conducted cross-sectional surveys of a representative sample of the adult population, and convenience samples of female sex workers and male STI patients. Only one (0.025%) of 3990 community participants was HIV-infected, while 142 (3.6%) had treponemal antibodies. Treponemal antibodies were not associated with past genital ulcers, number of sexual partners or adverse outcomes of pregnancies; their prevalence did not increase with age and there was no concordance within couples. Thus, most individuals with treponemal antibodies were probably infected during childhood with a non-venereal treponematosis. Only 1/70 (1.4%) and 0/83 sex workers sampled in 2004 and 2005 were HIV-infected. The Comoros have been protected by their insular status, male circumcision and paucity of syphilis. HIV control should focus on sex workers.

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.
