全世界疟疾流行情况在1984～1985年仍未取得普遍改善,尤其在亚洲、美洲及农村经济开发地区持续恶化。仅中国和印度有下降趋势。不包括非洲地区,年发病数就有530万。但疟原虫对抗疟药物的抗药性严重地影响着抗疟方案的进行。因此,了解抗药性疟疾的地理分布,诊断方法,探索其抗性机理及寻找防治对策等已是刻不容缓的现实问题。现将几个问题分述如下。
The prevalence of malaria in the world has not seen a general improvement from 1984 to 1985, especially in Asia, the Americas and rural areas where economic development continues to deteriorate. Only China and India have a downward trend. Excluding Africa, there are 5.3 million annual morbidity. However, the resistance of malaria parasites to anti-malarial drugs severely affects the anti-malarial program. Therefore, understanding the geographic distribution of drug-resistant malaria, diagnosing it, exploring its resistance mechanism and finding control strategies are all immediate problems. Now a few questions are as follows.
