Randomized trial analyzes hepatitis C transmission in urban STD clinics, highlighting critical risk factors.

To evaluate the prevalence and risk factors for hepatitis C virus infection among non-injection drug users attending STD clinics.
Analyzed 1039 STD patients and 309 sex partnerships for anti-HCV prevalence.
Conducted logistic regression analyses to identify risk factors associated with anti-HCV.
Assessed RNA homology between partners to evaluate sexual transmission likelihood.
7% of males and 4% of females tested positive for anti-HCV.
Females with anti-HCV positive partners had a 3.7 times higher likelihood of being anti-HCV positive (P=0.039).
94% RNA homology among couples compared to 82% in randomly selected pairs.

Thomas et al. (1995) studied this question.
