【摘要】 目的研究疟疾流行规律,探讨防治措施与方法,控制疟疾流行,进一步消除疟疾。方法在建立健全市县、乡、村三级灭疟网的基础上,以自然村屯为单位,划分疟区,分类防治。全面防治阶段,按上年疟史率的高低分类防治,采取“三根治、一预防和两喷洒”的综合性措施;基本消灭疟疾阶段,采取血检发热病人为主(县为单位年血检率10%以上)和重点村屯居民血检以及血清学监测的“查源拔灶”措施;消除疟疾阶段,以“四热病人”血检为主(县为单位年血检率5%以上)和加强血清学的横向监测,进一步肃清残存传染源。结果发病率从1954年228.7/万降至1993年为零;居民血检原虫率从1951～1957年18.74%,降至1980年2.73%及1990年为零。发热病人血检阳性率从1980年8.21%降至1993年均为零。30个市县考核达标至今已有7～15年未发现当地疟疾病例;儿童间接荧光抗体阳性率为0.05%。结论研究的防治策略与技术措施科学有效,灭疟指标达到消除疟疾标准。更多还原

【Abstract】 Objective Investigate the prevalent regulation of malaria, discuss the control measures for control its prevalence and eradicate malaria. Methods Based on the establishment of county-township-village three level malaria network in the whole city, malarial control activities were performed with the village as unit after stratification and classification of malaria endemic areas. During the overall control period comprehensive measures were taken. In the period of basic elimination the measures of blood examination of feverish patients (with blood examination rate of 10% in a county) and the blood examination of inhabitants in foci of heavy endemic villages and seroepidemiological suveillance were conducted. In the period of elimination The measures of blood examination of patients with four kinds of fevers (coverage of 5% in a county) and crosssectional seroepidemiological surveillance were carried out. Results The incidence rate reduced from 228.7/10 000 in 1954 to 0 in 1993. The parasite rate in the inhabitants reduced from 18.74% in 1951～1957 to 0 in 1990. The positive rate of feverish patients reduced from 8.21% in 1980 to 0 in 1993. No local infections were detected in the last 7～15 years in 30 city/counties after attained the criteria of basic elimination. The positive rate for IFAT in children was 0.05%. Conclusion The Control strategy and technical measures are effective and all the results meet the criteria of elimination of malaria.更多还原
