广西1996～2003年艾滋病哨点监测结果分析

Analysis of data of AIDS sentinel surveillance from 1996 to 2003 in Guangxi province

目的充分利用广西壮族自治区艾滋病哨点监测资料,进一步掌握广西艾滋病流行现状,使其切实服务于政策开发、预防控制策略和措施的制定,以及干预活动的设计和效果评价。方法按照哨点监测方案在13个点对吸毒者、暗娼、性病门诊就诊者和孕产妇等人群进行监测,监测数据用EPI和SPSS统计软件进行统计分析。结果(1)吸毒人群共用注射器吸毒的比例高达50%以上,艾滋病病毒(HIV)感染在此人群中呈现持续上升的趋势:1996年的监测中未发现HIV感染者,1997年HIV感染率为2.5%,2003年上升为17.0%;(2)暗娼中从不使用安全套的比例较高,约为60.0%,这部分人群中已出现HIV感染;由于部分暗娼为吸毒者,以致某些地方感染率高达10.3%;(3)性病门诊就诊者中性传播疾病的罹患率很高,HIV感染者在各哨点中均有发现,感染率约为0.2%;(4)孕产妇的哨点中也发现了HIV感染者,感染率约为0.1%。结论广西艾滋病的流行已开始从高危人群向一般人群扩散,形势非常严峻。必须尽快采取有效的预防控制措施,减缓艾滋病在广西的流行速度。

Objective To fully utilize the data of sentinel surveillance in Guangxi Zhuang Autonomous Region and further understand local current HIV prevalence for the purpose of developing appropriate prevention and control strategies and approaches.Methods According to the sentinel surveillance scheme, surveillance was provided in 13 sentinel sites twice a year, The targeted group were injection drug users, commercial sex workers, STD patients and pregnant women, EPI and SPSS software were used to analyze the sentinel surveillance data. Results （ 1 ）Data from sentinel surveillance showed that more than half of the injection drug users shared injection equipment, and HIV prevalence among this group was increasing gradually. There was no HIV infection case in 1996, but the HIV prevalence increased from 2.5 % in 1997 to 17.0% in 2003;（2）60.0 % of the investigated conmmrcial ,sex workers never used condoms; there were HIV positive cases in this group, and some of them were drug users, which resulted in high HIV prevalence.（ up to 10.3 % ） ; （3）STD infection rate among visitors to STD clinics was quite high and. HIV infection cases were reported in all the sentinel sites; the HIV prevalence rate was about 0.2% ;（4）HIV cases were also found among pregnant women in our sentinel sites,with a prevalence about 0.1%. Conclusions HIV infection in Guangxi has spread from the risk population to the general population. The effective prevention and control measures must be implemented as soon as possible to slow down the spread of HIV/AIDS in Guangxi province.
