目的　了解云南省HIV/AIDS流行现状和趋势。方法　采用哨点综合监测、现患调查、高危人群常规筛检和自愿匿名检测 4种血清流行病学调查方法收集HIV流行资料和全省AIDS病例报告资料。结果　2 0 0 3年全省共监测各类高危和重点人群 10 6587人 ,发现HIV新检出者 2 4 5 3人 ,诊断艾滋病病人 172人 ,死亡81人。哨点监测静脉吸毒人群HIV感染率为 21.2 % (0.6% - 63.0 % ) ,8个地区静脉吸毒HIV感染率达高水平流行 ;性病门诊男性就诊者HIV感染率为 2.6 % (0 - 10.8% ) ,其中思茅地区孟连县性病门诊男性就诊者HIV感染率为 10.8% ;孕产妇HIV感染率为 0.4 % (0 - 1.3% ) ,其中德宏州陇川县、盈江县医院孕产妇HIV感染率达到 1.3%、1.0 % ;昆明暗娼、嫖客HIV感染率分别为 2.5 %、0.8% ,全国HIV流调暗娼感染率 3.74 % (46/1230 ) ;高流行地区医院无关联人群HIV感染率为 1.3% ,献血员 0.07% ,自愿匿名咨询检测检出率为 13.1%。感染者主要为20-30岁汉族男性静脉吸毒者，以农民和无业人员居多，主要分布于我省德宏、红河、大量、昆明、临沧和保山。结论云南省HIV流行经静肪吸毒人群蔓延到全省，HIV感染率继续上升，并且造成性乱人群中的传播和流行，孕产妇人群HIV感染率进一步上升，高流行地区医院无关联人群HIV流行率超1%.全省面临艾滋病广泛流行的严重威胁。

Analysis on Survey Results of HIV/AIDS in Yunnan Province in 2003

Objective To learn the epidemic situation and tendency of HIV/AIDS in Yunnan province. Methods Adopting 4 serological and epidemiological methods such as sentinal surveillance, cross-sector survey, routine screening for high-risk people and voluntary anonymous test to collect epidemic data and reported cases data of HIV/AIDS in Yunnan province. Results Total of 105.587 high-risk people were surveyed in the whole province in 2003, of which there were 2 453 newly detected cases and 172 diagnosed AIDS patients and 81 deaths. The rate of HIV infection of venous drug addicts at surveillance sentinel was 21.2%(0.6%-63.0%),and the rate of venous drug addicts in 8 areas had reached a high level. The rate of HIV infection of male outpatients at venereal diseases clinics was 2.6%(0-10.8%),of which the rate of male outpatients at venereal diseases clinics in Menglian county of sima region was 10.8%; the HIV infection rate of pregnant and lying-in women was 0.4(0-1.3%), of which the rate of pregnant and lying-in women in the hospitals in Longchuan county and Yingjiang county of Dehong region was 1.3% and 1.0%; the HIV infection rate of unrelated people in hospitals of highly prevalent area was 1.3%; and that of blood donors was 0.07%, the positive rate among voluntary anonymous people was 13.1%. The infected people were mainly 20 to 30 years old male venous drug addicts of Han nationality, of which peasants and loafers took a large part, mainly distributing in Dehong, Honghe, Dali, kunming, Lincang and Baoshan of Yunnan Province. Conclusion The HIV infection of venous drug addicts prevailed with a increasing infection rate in Yunnan province, and caused HIV propagation and prevalence among sex promiscuity people. For pregnant and lying-in women, HIV infection rate had been increasing further, and the prevalence rate of unrelated people had been over 1% in the hospitals of highly prevalent areas. So the whole province was threatened by AIDS wide prevalence.
