Infection by hepatitis B and C virus in non-intravenous drug using female prostitutes in Spain

We have studied the prevalence of hepatitis B (HBV) and hepatitis C virus (HCV) serologic markers in female blood donors and in female prostitutes and the relationship of antibodies to hepatitis B core antigen (anti-HBc) and of antibodies to HCV (anti-HCV) with the presence of treponemal antibodies (FTA-ABS) in non-intravenous drug using female prostitutes. Hepatitis B surface antigen (HBsAg) was found in 1.0% of the female blood donors, anti-HBc in 15.6% and anti-HCV in 0.7%. In the prostitutes, the prevalence of HBsAg was 6.1%, anti-HBc was positive in 29.0% and anti-HCV in 8.8%. No significant statistical association between the prevalence of anti-HBc or anti-HCV and the age of prostitutes (p = 0.9111 and p = 0.8254 respectively) or the length of time as prostitutes (p = 0.3583 and p = 0.5770) was found. FTA-ABS positive prostitutes had a significantly higher prevalence of anti-HCV than FTA-ABS negative prostitutes (p < 0.001). No statistical association was found between anti-HBc antibodies and positive FTA-ABS prostitutes (p = 0.336).
