Prevalence and risk factors of syphilis infection among drug addicts.

Abstract

BACKGROUND: Recent epidemiological data show an increased trend of official estimates for syphilis infection in the general population. Many of the infected cases remain undetected leaving an underestimation of the true prevalence of syphilis in the general population, but also among subpopulations such as illicit drug users. There is limited epidemiological data published on the proportion and risk factors of syphilis infections associated with illicit drug abuse. METHODS: Illicit drug addicts (n = 1223) in inpatients units in Germany were screened (2000-01) for syphilis and interviewed regarding patterns of drug use and sexual behaviour. TPHA-test for initial screening and FTA-ABS-IgM test..
