近年来,男男性行为者(MSM)感染HIV人数出现快速增长,成为艾滋病疫情上升的主要原因之一。由于MSM人群高度的隐蔽性等特点,目前尚无有效的干预手段。随着互联网的普及,越来越多的MSM人群使用互联网来寻找性伴,其性伴数和HIV相关危险性行为都呈上升趋势。本文就基于互联网的MSM人群艾滋病流行病学相关研究与进展进行综述。 In recent years, there has been a rapid increase in the number of MSM infected with HIV, which has become one of the major causes of the AIDS epidemic. Due to the high degree of covert MSM population and other characteristics, there is no effective means of intervention. With the popularization of the Internet, more and more MSM people use the Internet to find their partners, and their sexual partners and HIV-related dangerous behaviors are on the rise. This article reviews the research and progress on HIV epidemiology of Internet-based MSM population.
