Abstract
We conducted an anonymous cross-sectional seroprevalence study of a population with a low frequency of injection drug use to determine whether persons with a history of cosmetic procedures, such as tattooing and body piercing, or intranasal drug use were at increased risk for hepatitis C virus (HCV) or hepatitis B virus (HBV) infection. Students 18 years and older from eight college campuses in Houston, Texas, were invited to participate in the study. Of the 7,960 who completed a self-administered questionnaire and provided a blood sample, 5,282 U.S.- or Canadian-born participants were analyzed. Their median age was 21, 62% were female, 42% were white, 26% black, 22% Hispanic, and 10% Asian or other. Two percent reported injection drug use, 13.7% intranasal drug use, 21.2% body piercings, and 25.2% tattoos. The overall prevalence of HCV infection was 0.9% and of HBV infection was 5.2%. Higher HCV prevalence was independently associated with increasing age (odds ratio [OR] per year = 1.11; 95% confidence interval [CI] = 1.08-1.14), history of injection drug use (OR = 18.24; 95% CI = 7.74-42.92), blood transfusion before 1991 (OR = 3.21; 95% CI = 1.02-10.12), and incarceration (OR = 3.48; 95% CI = 1.45-8.37). Among 5,066 students who denied injecting drugs, HCV prevalence was 0.8% in those who reported intranasal drug use and 0.6% each in those who reported tattoos and those who reported body piercing. Increased HBV prevalence was associated with high-risk sexual behaviors and black or Asian race. In conclusion, there was no increased risk for HCV or HBV infection in low-risk adults based solely on history of cosmetic procedures or snorting drugs. However, proper infection control practices for cosmetic procedures should be followed, illegal drug use discouraged, and hepatitis B vaccination provided to adolescents and sexually active adults.

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
