Abstract:

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５８６８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３７７３７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

English Abstract:

Objective To monitor the epidemic trends and explore effective strategies to control the epidemic of HIV. Methods HIV infection rates among different groups were monitored using sentinel surveillance strategy while the actual number of people infected with HIV and overall prevalence were estimated based on the surveillance. Results From 1989 to 1998, a cumulative of 5 868 HIV infections and 229 AIDS cases were reported from 103 of 126 counties in Yunnan. Among them, 15 counties were classified into high epidemic level, 8 were in middle level and rest in low level. The epidemic spread from countryside to cities and from borders to inland gradually. The proportion of farmers among all occupations dropped year by year. Unemployed people accounted for 50.2% of total reported infections in 1998. Male to female ratio dropped from 20 in 1989 to 3 in 1998. Injecting drug use and sexual transmission accounted for 73% and 13.6% of total HIV infections respectively reported in 1998. On average, the prevalence of HIV infection were 24.4% in injecting drug users, 2.4% among prostitutes, 1.6% among STD patients, and 0.2% among pregnant women of HIV infections was 37 737 until 1998. The prevalence rate among adults aged 15 to 49 years was 0.15%. Conclusion The epidemic of HIV infection keep spreading in Yunnan and vigorous responses for controlling the epidemic need to be launched urgently.
