目的了解柳州市1996-2010年人类免疫缺陷病毒感染者(human immunodeficiency virus,HIV)和获得性免疫缺陷综合征病人(acquired immuno deficiency syndrome,AIDS)流行病学特征,为制订防控措施提供科学依据。方法对1996-2010年艾滋病疫情报告和流行病学调查资料进行统计分析。结果柳州市艾滋病感染情况呈明显上升趋势,所辖区县均有病例出现,总体呈弥漫性扩散趋势,感染病例已进入发病和死亡高峰;男性高于女性,女性比例有所增加;20～39岁年龄组为主,约占50%;40～59岁及60岁以上人群所占比例逐年增大;以农民和家务待业人员为主,约占60%,农民所占比例逐年增大;以异性性传播为主,占80%以上;非婚异性性行为是异性性传播的重要影响因素,样本来源中临床医疗机构占了新报告病例的75.1%,是最主要的疫情报告来源。结论柳州市HIV/AIDS流行情况愈趋严重和复杂,控制传染源,切断传播途径,保护易感人群是防止艾滋病向普通人群蔓延的重要策略。
Objective To understand the epidemiological characteristics of human immunodeficiency virus (HIV) and acquired immuno-deficiency syndrome (AIDS) from 1996 to 2010 in Liuzhou and to provide a scientific basis for the development of prevention and control measures .
