Prevalence of Hepatitis and Injection Drug Use
"The hepatitis prevalence rates among ever-IDUs at treatment was obtained analogously to the HIV prevalence rate described above, and was also collected through Standard Table 9. An overview of the hepatitis B and C prevalence rates for 2003-2010 are given in Table 6.3 and Table 6.4, respectively (ST9P2_2003-2011_BE). Regarding Hepatitis B, 2.8% (Free Clinic) and 0% (De Sleutel) of the patients tested in 2010, tested positive for HbsAg, 56.3% (Free Clinic) and 0% (De Sleutel) for antiHBC and 55.2% (Free Clinic) and 20.0% (De Sleutel) for antiHBs. Regarding Hepatitis C, 80% (Free Clinic) and 28.1% (De Sleutel) of the patients tested positive for HCVab in 2010. The patient population of the Free Clinic is known to be a strongly marginalized population, explaining the high prevalence rates. Comparing the results for the 2010 prevalences with previous years, does not reveal significant time trends."
