1800 cases of poliomyelitis has been observed in Mali during 8 years from 1968 to 1975. Children, and specially infants from 6 months to 2 years are specially concerned with a sex-ratio giving a higher frequency in boys though this difference goes decreasing with age. The dry season and the hotter one are the two periods of great morbidity. The three types (I, II, III) have the same importance. Oral immunization at the age of 3 or 4 months must be extended.
1968年至1975年的8年间，马里共观察到1800例小儿麻痹症病例。儿童，尤其是6个月至2岁的婴儿特别容易感染，男女性别比显示男孩的感染频率更高，不过这种差异会随着年龄的增长而减小。旱季和炎热季节是发病率极高的两个时期。三种类型（I型、II型、III型）的重要性相同。必须扩大3或4个月大时的口服免疫范围。
