江苏省经异性性行为感染HIV病例感染方式及经商业异性性途径感染HIV病例确证阳性前后性行为调查分析

摘要：目的 分析江苏省经异性性行为感染HIV病例性行为感染方式及经商业异性性行为感染病例确证阳性前后性行为特征。方法 选取2014年1-6月报告经异性性行为感染HIV病例，询问具体感染方式，调查商业异性性传播病例确证前后性行为信息。结果 调查对象以商业异性性传播为主，占57.21%，但女性主要为婚内传播。经商业异性行为感染病例同时存在固定和临时性行为，三种性行为的比例由确证前100.0%、14.35%和17.72%降至确证后7.59%、5.06%和2.95%，但未坚持使用安全套、性伴不告知和不知晓性伴感染状态等传播风险仍然存在。调查对象的感染及感染后的传播均主要发生在本省内。结论 除继续推行现有的干预措施外，还应进一步缩短发现到治疗的时间以及推进“配偶强制告知”政策的落实。

Classification of heterosexual transmission route and characteristics of HIV cases infected through commercial heterosexual transmission in Jiangsu Province, China, 2014

Abstract Objective: To explore the specific classification of heterosexual transmission route among HIV/AIDS, and clarify the sexual behaviors of commercial heterosexual transmitted HIV cases in Jiangsu, China. Methods: HIV cases reported from January to June in 2014 and infected through heterosexual transmission route were recruited. The specific heterosexual transmission route and sexual behaviors before and after HIV confirmed positive were investigated. Results: The commercial heterosexual mode was the most common transmission route in Jiangsu Province, however, marital heterosexual mode was the major route for female participants. Participants infected through commercial heterosexual route also had regular and casual sexual behaviors simultaneously. Although the proportions of commercial, regular and casual sexual behaviors were decreased from 100.0%, 14.35% and 17.17% before HIV confirmed positive to 7.59%, 5.06% and 2.95% after HIV confirmed positive, the proportions of condoms used consistently, disclosing infection status to sexual partners and sexual partners knowing the infection status of the HIV cases were not high. Infection source and the secondary spread were mainly in Jiangsu Province. Conclusions: Targeted preventive measures should continue to be pushed; shorten the time from confirmed to treatment and strategies on partner notification should be carried out to decrease the risk of HIV infection immediately.
