我国男男性行为人群艾滋病流行情况及HIV-1基因亚型特征

AIDS epidemic among men who have sex with men in China and related HIV-1 genetic subtypes

我国男男性行为（MSM）人群中艾滋病的发病率呈逐年上升趋势，需要引起社会重视。近年来，我国MSM人群中各种新HIV-1独特重组型（URFs）和流行重组型（CRFs）不断被发现，CRF01-AE和CRF07-BC已经成为我国主要的HIV-1流行亚型。及时发现和鉴定各种HIV-1亚型，对预防和控制艾滋病流行具有重大意义。

The prevalence of HIV among men who have sex with men （MSM） in China is increasing year by year, which is associated with a variety of factors and should be aroused social attention. In recent years,various novel unique recombinant forms（URFs） and circulating recombinant forms（CRFs） have been identified in MSM in China, CRF01_AE and CRF07_BC are the primary HIV-1 genetic subtypes. Timely discovery and identification of various HIV-1 genetic subtypes will play an important role in preventing and controlling epidemic of AIDS.
