2006年浙江省疟疾重点监测县疫情分析

目的 通过对2006年浙江省疟疾重点监测县(市、区)疫情分析,了解新形势下浙江省疟疾流行特征,为制定新的防制策略提供科学依据.方法 对三热病例进行血检,对疟疾病例进行流行病学个案调查,对疟疾媒介进行分类鉴定,对部分人群进行疟疾抗体监测.结果 15个疟疾重点监测县(市、区)共145例疟疾病例,年发病率1.76/10万.本地发热病例血检疟原虫阳性34例,阳性率为0.16%;外来流动人口发热病例血检疟原虫阳性111例,阳性率为2.28%.本地感染者占病例总数14.48%;输入病例占总病例数85.52%,其中,外来人口占输入病例89.52%,本省人口外出感染占输入病例10.48%.结论 浙江省外来流动人口疟疾输入病例呈逐年上升趋势,因此,要制定适应新形势的防疟措施,加强疟疾的监测力度.

Epidemiological analysis on malaria in focally supervised counties in Zhejiang Province in 2006

Objective The study provided an insight into the current epidemiological characteristics of malaria in Zhejiang Province by analyzing the malaria epidemic in focally supervised counties (cities,districts)in Zhejiang in 2006,in favor of the development of new control strategies.Methods "Three fever"patients were required to receive blood test.Epidemiological case investigation was performed for malaria patients,with the malaria media indentified and classified.Monitoring of malaria antibody was conducted for some of the patients.Results There were 145 malaria patients from 15 focally supervised counties(cities,districts),with the annual incidence being 1.76/lakh.Blood test revealed 34 cases of positive plasmodium with the positive rate of 0.16%;and 111 cases of positive plasmodium among floating population,with the positive rate being 2.28%.Local infected patients accounted for 14.48% of the total cases,while the import cases for 85.52%.Immigrant patients accounted for 89.52% of the import cases,and local travelers for 10.48%.Conclusion A rising trend by year of import malaria cases in the floating population was found in the study.Hence,it was necessary to formulate anti-malaria measures adaptable to the new circumstances to intensify the surveillance of malaria.
