Short report: prevalence of hepatitis C viral antibody among Brazilian children, adolescents, and street youths.

The prevalence of hepatitis C antibodies (anti-HCV) was investigated in 1,378 central Brazilian children, students, and street youths (homeless adolescents without family links or adolescents working in poorly paid activities). Sera were tested with a second generation enzyme-linked immunosorbent assay, and positive samples were retested by a confirmatory assay (line immunoassay). All children attending day care centers were anti-HCV negative.

High prevalence of hepatitis C infection among Brazilian hemodialysis patients in Rio de Janeiro: a one-year follow-up study.

Nearly 400 hemodialysis patients treated at 5 different hemodialysis units in Rio de Janeiro were tested for one year for the presence of hepatitis C and B markers. During the same period, samples were also obtained from 35 continuous ambulatory peritoneal dialysis (CAPD) patients and from 242 health care workers. Depending on the hemodialysis unit studied, anti-HCV prevalence rates ranging from 47% to 82% (mean 65%) were detected.
