Abstract:
Objective:To explore incidences of HIV and HCV infections in injecting drug users (IDUs) in community.Methods:A community-based survey was conducted to recruit 200 HIV sero-negative IDUs for a prospective cohort study based on the local needle and syringe exchange program in Longyang district of Baoshan city, Yunnan province from June 2014 to June 2019, China. Follow-up was carried out every six month to investigate the prevalence of drug use behavior and sexual behavior in IDUs. Blood samples were collected from them to test HIV and HCV serum antibodies. The cohort was opened for recvuitment every year to replenish the cohort to 200 subjects.Results:A total of 231 IDUs were recruited after 5 years of follow-up. Cohort retention rate was 82.0% (164/200) in 5 years. No HIV sero-positive conversion was found during the 5-year study. There were 89 HCV negative IDUs. Totally, 384.6 person years were observed and the HCV sero-positive conversion in this cohort was 0.26 per 100 person-years.Conclusion:It was found that the incidences of HIV and HCV in IDUs in communities of the study area were at low levels, while comprehensive and effective intervention measures are still needed to control HIV and HCV infections in this population.
