改善发展中国家千百万人民生活条件的战略规划应包括对热带病的防制。热带病防制的策略应有简单、有效与安全的方法,包括疫苗、药物及诊断试验。目前用以防制热带病的方法看来是不甚合适的。主要的热带寄生虫病尚无疫苗。因治疗药物的疗效欠佳或不够安全或因抗性株的出现使集体治疗受到了限制。某些疾病甚至还缺少化学治疗方法。防制新药的研究受到限制的主要原因为:(1) 增加了疗效与安全试验的有关条理的规定;(2) 生产有效化合物的特需固定设备维修费用的支付;(3) 在流

The main reasons for the limited control of new drugs are: (1) the provisions for the treatment and safety tests have been added; (2) the payment of maintenance costs for special equipment needed to produce effective compounds; (3)
