Objective To understand the epidemiological characteristics of malaria in Xishuangbanna in recent 30 years and evaluate the control effort, and provide evidence for the eradication of malaria. Methods The incidence data of malaria in Xishuangbanna from 1981 to 2010 were collected from the annual reports of malaria in Xishuangbanna and from national database for disease control and prevention to conduct descriptive epidemiological analysis, and the control effect was evaluated. Results A total of 56 934 malaria cases, including 73 deaths, were reported during this period. Among these cases, 42 268 were tertian malaria cases (8 deaths), 13 330 were malignant malaria cases (62 deaths) and 1336 were unspecified malaria cases (3 deaths). In 1981, a total of 4184 cases were reported, the incidence was 660. 25/lakh. In 2010, only 30 cases were reported, the incidence was 2. 79/lakh. More cases occurred in males than in females. The cases were mainly distributed in young adults aged 15-35 years. Farmers, workers, students and children outside child care setings were the major populations affected. The disease mainly occurred during May-September of a year. Conclusion Malaria is under effective control with the incidence declined year on year in Xishuangbanna after the 30 years effort of malaria prevention and control. The local transmission level of the disease is low, but the imported malaria highlights the importance of continued prevention and control of the disease in Xishuangbanna.%目的 了解云南省西双版纳州近30年疟疾流行病学特征,对疟疾控制效果进行评价,对今后消除疟疾工作提供参考依据.方法 疫情资料来源于西双版纳州1981-2010年疟疾年度报表及中国疾病预防控制信息系统数据,对30年疟疾发病情况进行描述性分析,并对控制效果做出初步评价.结果 1981-2010年西双版纳州共报告疟疾病例56934例,死亡73例,其中,间日疟42268例,死亡8例,恶性疟13330例,死亡62例,未分型1336例,死亡3例.1981年报告发病数4184例,发病率660.25/10万,2010年报告发病数30例,发病率2.79/10万.人群分布男性多于女性,高发年龄段在15 ～35岁之间,以青壮年为主,职业分布以农民、工人、学生及散居儿童为主.季节分布分析,作为虫媒传染病,流行的季节和媒介消长时间密切相关.根据近30年西双版纳州疟疾发病情况分析,疟疾流行季节为5-9月.结论 通过30年来的疟疾防治,西双版纳州的疟疾发病得到了有效的控制,发病率逐年下降,该州疟疾已经处于低流行状态.由于境外疟疾的高度流行及输入性风险,加重了西双版纳地区疟疾防控的压力.
