Investigation on new infection rate of HIV-1 among MSM in Qinghai from 2009 to 2011
Bibliographic record
Abstract
Objective To know about the infection status of HIV-1 among MSM in Qinghai.Methods The cross-sectional survey of Qinghai Province in the second quarter of three consecutive years from 2009 to 2011 were conducted on MSM.The monitoring samples collected from MSM population in national sentinel were done with preliminary screening and confirmatory test by ELISA and WB method.Then the samples which were recognized as serological HIV-1 positive were detected by the BED HIV-1 capture enzyme-linked method(BED method),so as to estimate new infections.Results A total of 128 HIV-1 positive samples were sifted out from 1 382 samples,including 113 cases detected by BED method and 59 cases determined as newly infected.The new infection rate of the 3 years was 8.14%,9.77%,and 11.13%,respectively.Conclusions The new infection rate of HIV among MSM remained at a high level in Qinghai.The rate of 2011 was more than 10% which suggested that the crowd present a high level of HIV infection which may become bridge populations spread to the mainstream crowd.Thus we should take effective measures to control the wide spread of AIDS in MSM and further block the spread of the epidemic to the general population.

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.
