目的通过对新会区戒毒所吸毒人员 HIV、HCV 和梅毒的检测，了解吸毒人群经血传播疾病的危险因素，为预防控制艾滋病在吸毒人群的流行提供科学依据。方法对新会区2011年戒毒所的436例吸毒人员进行问卷调查，采取静脉血的方法抽取血样，进行 HIV、HCV 和梅毒抗体检测，并对结果进行统计和分析。结果436例吸毒人员 HIV 感染率为3.4%(15/436)，HCV 感染率为36.9%(161/436)，梅毒感染率为9.4%(41/436)。HIV、HCV 的感染途径以共用注射器静脉吸毒为主。结论被调查人群中存在血源性疾病传播和流行的风险，应加强对吸毒人群的监测，同时开展防病知识宣传教育和行为干预，以降低 HIV、HCV 和梅毒在该人群中的传播和扩散，控制艾滋病等血源性传染病的蔓延和流行。% Objective The present study was conducted to investigate the status on the infection of HIV, HCV and Syphilis in a drug rehabilitation center in Xinhui and find out the risk factors that the diseases were transmitted by blood route among drug addicts in order to provide scientific basis for the prevention and control of AIDS among this population. Methods Antibodies of HIV, HCV and Syphilis were detected in 436 drug addicts of a voluntary drug rehabilitation center in Xinhui in 2011 and the results were analyzed. Results The infection rate of HIV was 3.4%(15/436), HCV 36.9% (161/436), and syphilis 9.4%(41/436). HIV and HCV were mainly transmitted by sharing syringes among the intravenous drug users. Conclusion There existed the risk that blood-borne diseases were transmitted and spread among the investigated drug addicts. It is necessary to enhance surveillance, education on the prevention of the diseases and behavioral intervention for drug addicts so as to reduce the transmission and spread of HIV, HCV and syphilis in the population,and control the spread and prevalence of blood-borne infectious diseases such as AIDS.
