Purpose: The Prevalhep study seeks to determine the prevalence of factors associated with hepatitis C virus (HCV) and B (HBV) in Spanish prisoners Methods: Observational, cross-sectional study which randomly selected 18 Spanish prisons to participate, and with 21 prisoners/CentreResults: There were 378 prisoners selected, 370 of whom had serological HCV and 342 had VHB data. The HCV population were predominantly male (91.6%), of middle age (66.7% contact status with HBV (HBcAb+ and/or HBsAg+), while 37.5% were susceptible to HB.
Conclusions:The prevalence of HBV and HCV has decreased in the Spanish prison population, probably as a result of decrease in IDU transmission, and an increase in immigrant prisoner population that does not have this risk behaviour.[Word count = 198]
