本文根据巴西卫生部提供的资料,应用指数函数公式Y=aeb~t,在Hewlett-Packard YI/O 167-C计算器上,进行“指数拟合”预测2000年前的麻风发现率,以指数方程的斜率“b”作为评价麻风流行增加或降低的指标,对巴西1950～1987年的麻风流行趋势进行了分析,从而为确定工作重点、制定更有效的控制规划服务.作者对两个期间的麻风流行进行了分析.1950～1968
Based on the information provided by the Brazilian Ministry of Health, this paper predicts the leprosy detection rate by 2000 with “exponential fitting” on the Hewlett-Packard YI / O 167-C calculator using the exponential function formula Y = aeb ~ t, Taking the slope of exponential equation “b ” as an index to evaluate the increase or decrease of leprosy epidemic, the epidemic trend of leprosy in Brazil from 1950 to 1987 was analyzed to establish more effective control planning service in order to determine the key points of work. The prevalence of leprosy during the two periods was analyzed .1950 ~ 1968
