目的了解广西某市新报告艾滋病感染者的感染途径,根据现阶段的艾滋病流行特征和趋势制定有针对性的防治策略。方法对广西某市2009年5月1日至8月31日确认为新报告的HIV感染者/艾滋病患者以及他们所提供的高危行为接触者进行问卷调查,详细了解其高危行为信息,分析感染途径。对未知艾滋病感染状况的溯源对象采血进行HIV抗体检测。结果共完成3个层次的溯源调查,共调查165名HIV感染者/艾滋病患者及其高危行为接触者,确认为HIV感染者/艾滋病患者156例,其中HIV感染者106例,艾滋病患者50例。经固定异性性接触途径传播占48.7%(76例),经商业异性性接触途径传播占29.5%(46例),经吸毒途径传播占9.6%(15例),经非固定非商业性接触途径传播占9.0%(14例),经母婴途径传播占1.3%(2例),经性与吸毒途径传播占1.9%(3例)。结论广西某市新报告的艾滋病感染者的感染途径以配偶等固定异性性途径感染为主,今后要进一步加强艾滋病各项综合防治措施,特别是要控制艾滋病经配偶或固定性伴间的传播,减少二代感染。
Objective To understand the new ways of HIV infection in a city of Guangxi and to formulate targeted prevention and control strategies according to the characteristics and trends of AIDS epidemic at this stage. Methods A questionnaire survey was conducted among HIV-infected persons / AIDS patients who were confirmed as newly reported in Guangxi from May 1 to August 31, 2009 and the high-risk sex workers they provided, to learn more about their high-risk behaviors and to analyze the routes of infection . HIV antibody testing was performed on the traceable source of unknown HIV status. Results A total of three levels of traceability surveys were conducted. A total of 165 HIV / AIDS patients and their contacts with high-risk behaviors were investigated and confirmed as 156 HIV / AIDS patients, including 106 HIV-infected patients and 50 AIDS-infected patients.
