Using official epidemiological informations, authors study evolution of sleeping sickness epidemiological situation in seven OCCGE countries: Benin, Ivory Coast, Upper Volta, Mali, Niger, Senegal and Togo. 745 new cases were diagnosed in 1977 and more than 600 in 1978. We observe the extinction of historic foci in Niger and Senegal, the persistance of foci in Upper Volta and Mali and the reviviscence of foci in Benin, Ivory Coast and Togo. One of the prominent points of the present endemia is the importance of people migrations, especially between Ivory Coast and Upper Volta. It would be of major interest to enter upon an epidemiological study of this problem. An outline of situation in neighbouring countries is given. The important reviviscence of certain foci must lead to increase energies for medical surveys and vector control.
作者利用官方流行病学信息，研究了贝宁、象牙海岸、上沃尔特、马里、尼日尔、塞内加尔和多哥这七个赤道非洲国家锥虫病流行病学情况的演变。1977年诊断出745例新病例，1978年超过600例。我们观察到尼日尔和塞内加尔的历史疫源地消失，上沃尔特和马里的疫源地持续存在，贝宁、象牙海岸和多哥的疫源地复苏。当前这种地方病的一个突出问题是人口迁移的重要性，尤其是在象牙海岸和上沃尔特之间。对这个问题进行流行病学研究将具有重大意义。文中给出了邻国的情况概述。某些疫源地的重要复苏必然要求加大医学调查和病媒控制的力度。
