中国云南省瑞丽等地艾滋病病毒Ⅰ型C亚型的分布研究

１９９４年中国预防医学科学院艾滋病监测中心与美国ＣＤＣ合作，首次发现在中国云南省存在ＨＩＶ－１Ｃ亚型病毒的流行，为了解该省Ｃ亚型流行分布及流行时间，取“八五”国家科技攻关项目采集的静脉吸毒者ＨＩＶ－１抗体阳性血清共１９２份，用特异肽ＥＬＩＳＡ进行测定，结果表明１９９２年Ｃ亚型在瑞丽开始出现５．１％，１９９３年Ｃ型瑞丽达１２．９％，陇川达３０．４％，１９９４年Ｃ亚型主瑞丽达３１．９％，陇川达３３．３

Study on the Distribution HIV-1 C Subtype in Ruili and other Counties, Yunnan, China

Cooperating with CDC, USA, the Center for AIDS Surveillance, Chinese Academy of Preventive Medicine, first identified the epidemic of HIV-1 C subtype virus in China in 1994. As part of the Eighth-Five National Scientific Program and to get information about the geographical distribution of C subtype of HIV-1 and its epidemic time span in Yunnan, using specific peptide ELISA, we tested 192 anti HIV-1 positive serums,among intravenous drug users. The results indicated that C subtype of HIV-1 started to appear in Ruili (5.1%)in 1992,and the rates were 12.9% in Ruili and 30.4% in Longchuan in 1993,up to 31.9% in Ruili and 33.3% in Longchuan in 1994. The porpotion of C subtype is increasing among the drug users by year. Whether C subtype would become the main the main epidemic subtype in this areas remains to be under observation.
