疟疾血清流行病学调查已广泛用于流行区程度的判定、疟疾防制效果的考核和控制后期易感人群及地区的监测。为探明单次横向血清学调查能否反映出泰国疟疾的流行情况,以及比较酶联免疫吸附试验(ELISA)和间接血凝试验(IHA)在评价疟疾流行程度中的效用,作者于1982年4月在泰国选择三个以恶性疟为主的村庄进行了研究。所选的三个村中,第11村处于防制的早期阶段,DDT喷洒和主动、被动检测病例同时进行,当年成人血检原虫阳性率为15.2％;
Serological epidemiological survey of malaria has been widely used in the determination of endemic area, the evaluation of malaria control effect and the monitoring of late-stage susceptible population and area. To determine whether a single horizontal serological survey can reflect the prevalence of malaria in Thailand and compare the utility of ELISA and indirect hemagglutination (IHA) in assessing the prevalence of malaria in Thailand, A study was conducted in Thailand in April on the selection of three predominantly falciparum villages. Among the three selected villages, the 11th village was in the early stage of prevention and control. The DDT spraying and the active and passive test cases were carried out at the same time. The positive rate of blood test was 15.2%.
