目的：探讨五指山区近年来恶性疟发病规律，为加强疟疾防治提供依据。方法：收集区内1993—1996年各年度恶性疟疾人管理卡和疫点处理登记卡，进行统计分析。结果：区内发病呈下降趋势，1996年恶性疟带虫发病率及其在疟疾中比例，已降至1／万以下和5％左右的低水平，病例中以男性青壮年为主，呈激发性，每年6—9月份为发病高峰季节，除村寨和上山感染外，外地输入也是重要的来源，流动人口增多和灶点处理拖延是导致1994年发病明显回升的主要原因。结论：采取强化灭源结合灭媒的措施，及时管好病人和病灶，以及流动人口，是继续巩固和发展防治成果的主要措施。
Objective: To explore the law of incidence of falciparum malaria in Wuzhishan mountainous area in recent years and provide basis for strengthening the prevention and treatment of malaria.
