摘要
目的分析四川省疟疾流行态势与消除疟疾工作进展情况。方法对全省疟疾发病与流行态势进行描述性研究。结果 1950-2012年四川省疟疾发病人数由最高时的58多万下降到近年的100余人,下降达99.98%以上,已连续19年年发病率控制在1/万以下;自2011年及以后全省本地疟疾病例报告均为0,即输入病例占总病例的100%;输入病例散在分布,全年均有发病,无明显季节分布;人群感染以男性为主（男：女=26.5：1）;职业以农民及农民工和工人为多（占72.25%）;年龄集中在青壮年（20-59岁）占95.15%;输入病例中,恶性疟占输入总病例的57.42%,主要输入地为非洲和东南亚。结论四川省疟疾发病大幅度下降,疟防进程已由控制阶段走向消除阶段。在此基础上,应进一步加强疟疾监测和流动人员管理,加快消除疟疾工作。

Results Through the period of 1950- 2012,the patients with malaria had dropped from 580 000 in peak- incidence years to 100 people in recent years,with a drop rate of 99. 98%. The incidence kept below 10 /105 in recent 19 consecutive years. The number of local- reported cases was 0 since 2011 and instead,imported malaria cases accounted for 100% of the total cases. The imported cases showed diffused distribution and were reported all the year round,without obvious seasonal distribution. People infected were mainly male（male： female = 26. 5： 1）.The occupations of the cases were farmers,migrant workers and workers,together accounting for 72. 25% of the total. The age of onset concentrated in young adults of 20- 59 years old,accounting for 95. 15%. Of the imported malaria cases,Plasmodium falciparum accounted for 57. 42% and the main input areas were Africa and Southeast Asia. Conclusion The incidence of malaria in Sichuan has declined sharply and the prevention work of malaria has turned into eliminating phase from phase of prevention and control. To speed up the eliminating work,surveillance work and management work on migrant people are to be further strengthened.
