目的 研究云南省艾滋病病毒（ＨＩＶ） 感染流行十年来的特征和趋势，讨论云南省对ＨＩＶ 的流行与控制。方法 用哨点监测的方法纵向观察和比较各类人群流行率，估算ＨＩＶ 感染者总数和流行率。结果 云南省１９８９ ～１９９８ 年累计报告ＨＩＶ 感染者５ ８６８ 例，ＡＩＤＳ２２９ 例；累计流行县达１０３ 个，其中高流行县１５ 个，中度流行县８ 个。ＨＩＶ 流行由农村向城市蔓延、由边境向内地蔓延。ＨＩＶ 感染者在职业构成上农民的比例逐年下降，城市无业者所占比例至１９９８ 年已达５０．２ ％ ；在ＨＩＶ 感染者中男性／ 女性的比例到１９９８ 年为３∶１ ；在暴露因素中１９９８ 年因吸毒感染的占７３ ％ ，性传播占１３ ．６ ％ ；ＨＩＶ 流行率逐年上升，１９９８ 年静脉吸毒哨点ＨＩＶ 流行率全省平均为２４．４ ％ 、暗娼为２ ．４％ 、性病哨点为１ ．６％ 、孕产妇哨点为０ ．２ ％ 。全省至１９９８ 年累计ＨＩＶ 感染人数估计为３７ ７３７ 人，１５ ～４９ 岁成人ＨＩＶ 流行率为０．１５ ％ 。结论 云南省ＨＩＶ 流行在继续发展，加强对该病的防制力度迫在眉睫
Objective To study the characteristics and trends of HIV infection in Yunnan over the past ten years and to discuss the HIV epidemic and control in Yunnan Province. Methods The method of sentinel surveillance was used to vertically observe and compare the prevalence of various types of people and estimate the total number and prevalence of HIV infection. Results From 1989 to 1998, a total of 5868 cases of HIV infection and 229 AIDS cases were reported in Yunnan Province. A total of 103 endemic counties were found, of which 15 were endemic to the epidemic and 8 were moderately endemic. The spread of HIV from rural areas to cities spreads from the border to the interior. The proportion of HIV-infected persons in the occupational composition of peasants has been declining year by year. The proportion of urban unemployed people has reached 50.2% by 1998; the male / female ratio among HIV-infected persons was 3: 1 in 1998; Among them, 73% were drug-induced infections in 1998 and 13 were sexually transmitted. 6%. The prevalence of HIV increased year by year. In 1998, the prevalence rate of HIV among intravenous drug abuse sentinels was 24.4% on average in the province, and 2 for female sex workers. 4%, STD sentinel 1. 6%, maternal sentinel is 0. 2%. The cumulative HIV infection count in the province up to 1998 is estimated at 37,737 and the HIV prevalence among adults aged 15-49 is 0.15%. Conclusions The HIV epidemic in Yunnan Province is continuing to develop. It is imperative to strengthen the prevention and control of this disease
