Analysis of HIV/AIDS sentinel surveillance in Shenzhen

Objective To monitor the prevalence and the risk factors of HIV in high-risk population,so as to provide a scientific basis for policy-makers in evaluating the effectiveness of HIV prevention,and formulating strategic measures for HIV prevention and treatment.Methods In 2004 collected samples were screened for HIV antibody by enzyme linked immunosorbent assay(ELISA) in Shenzhen among 245 clandestine commercial sex workers(CSWs),1 100 outpatients visiting STD clinics and 852 drug users.Results The main groups of the STD outpatients in 2004 were unmarried men coming from other provinces,who were mainly infected with NGU,syphilis,and CA etc.In the year of 2004,three cases with positive HIV antibody were detected among this group of population and the rate of infection was 0.27%.Besides,the clandestine commercial sex workers(CSWS) were mainly unmarried women emigrating from other provinces,among whom the rate of using condoms was 73.9%,and the rate of drug use was 0.8%,but no injection drug use or syringe sharing was found.In the two rounds of sample screening among CSWs in 2004 no HIV carrier was found and the infection rate was 0%.Most of drug users were unmarried immigrants from other provinces and among them 27.7% used condoms,66.3% admitted that they had offered or received commercial sex services,and 55.5% used drugs by injection and sharing syringes with others.In 2004,ten cases with positive HIV antibody were identified among the drug users and the rate of infection was 1.2%.Conclusion The results of this surveillance indicate that HIV is prevalent among the high-risk population of IDU and STD outpatients and there exist a number of risk factors,leading to the prevalence of HIV in this municipality.
