免疫荧光抗体技术用于海南省毛阳疟疾防治试点流行监测

THE EPIDEMIOLOLGICAL SURVEILLIANCE IN MAOYANG MALARIA CONTROL TRIAL AREA IN HAINAN WITH IMMUNO FLUORESCENT ANTIBODY TECHNIQUE

目的 为了评价毛阳地区疟疾防治试点的发病率降至较低水平后的防治效果。方法 于 1999年再次应用 IFAT进行流行病学监测及原虫率考核。结果 什益管区和牙合管区居民抗体阳性率分别为 7.7%和 13.9% ;低年龄组抗体率为 3.1%和 7.8% ;原虫率相为 0 .6 0 %和 2 .6 0 %。结论 提示前一管区抗疟措施较有力 ,疟疾已降至低度 ,但低年龄组仍有阳性 ,传播尚未阻断 ;后一管区疟疾乃存在一定程度的流行 。

Objective In order to evaluate the malaria control effect of Maoyang area after the incidence rate reached a lower level.Methods Surveying epidemiologically the area with the indirect fluorescent antibody test(IFAT)and checking the parasite rate again in 1999. Results The antibody positive rates of the inhabitants of Shiyi district and Yahe district were 7,7% and 13.9% respectively,the antibody positive rates of the low age groups of them were 3.1% and 7.8% respectively,the parasite rates were 0.60% and 2.60% respectively.Conclusion It indicated the malarial prevalence of Shiyi district and already dropped to a low degree,but the positive cases still existed tn the low age groups and the transmission was not stopped yet.The malarial epidemic existed in some degree in Yahe district and should be controlled.
