Abstract:
Objective To understand the current status of malaria prevalence,its impacts and malaria transmission trends in Jiangsu Province. Methods The malaria incidence, and its symp- toms, mosquito preventive measures, Anopheles density, mosquito biting rates and related factors were investigated in malaria epidemic villages as surveillance sites such as Guanshan Town of Suin- ing County, Tangzhang Town of Tongshan County, Tianganghu town of Sihong County, Qiuji Town of Xuyi County and Zhangzhu Twon of Yixing City. Results In 2006,the bednet coverage was 20. 29% and bednet-using rate was 34. 32% in 27 903 residents of 7 921 households of 15 ad- ministrative villages. In 2005, 750 Anopheles sinensi were captured from 50 bednets in the early morning, the human biting ratio was 0.17/person per night, and in 2006, 1 927 Anopheles sinensi were captured from 50 bednets in the early morrung, human biting ratio was 0. 38/person per night. The average blood smear checking rate was 2. 72% (6 089 people) and the average positive rate was 0. 48% (29 plasmodium positive individuals). Conclusion The lower blood smear microscopy test- ing,few positive rates of febrile patients and increased Anopheles sinensis density were the main fac- tors of malaria relapses in the area of the North Huaihe River in Jiangsu Prownce.

摘要:
目的 了解江苏省疟疾的流行现状及其影响因素,掌握疟疾流行规律和趋势。方法根据疟疾发病情况,选择近年来发病率较高的睢宁县官山镇、铜山县棠张镇、泗洪县天岗湖镇、盱眙县仇集镇和宜兴市张渚镇作为疟疾监测点,调查居民疟疾发病情况、疟疾症状及防蚊措施、按蚊密度及叮人率等相关因素。结果2006年调查15个行政村,7 921户,27 903人,蚊帐拥有率为20. 29%;蚊帐使用率为34. 32%。2005年在清晨50顶蚊帐内捕获中华按蚊750只,平均叮人率为每夜0.17只/人;2006年在清晨50顶蚊帐内捕获中华按蚊1 927只,平均叮人率为每夜0. 38只/人。血检6 089人,平均血检率为2. 72%,检出疟原虫阳性29人,平均阳性率为0.47%。结论发热病人血检数量较少和镜检阳性率较低,中华按蚊密度增高是江苏省淮北地区出现疟疾疫情反复酌主要因素。
