High-risk behaviors for hepatitis B and C infections among female sex workers.

INTRODUCTION
The prevalence of hepatitis B and hepatitis C and risk behaviors among 402 female sex workers in Central Brazil were investigated by respondent-driven sampling.


METHODS
Blood samples were tested for hepatitis B and C markers by enzyme-linked immunosorbent assay. Two hepatitis B vaccination schedules were performed.


RESULTS
The prevalence of hepatitis B and C infections were 9.3% and 0.5%, respectively. Susceptibility to hepatitis B infection was observed in 61.5% of subjects. There was no significant difference in adherence index (p=0.52) between vaccination schedules and all participants had protective antibody titers.


CONCLUSIONS
This hard-to-reach population requires hepatitis B and C surveillance.
