自1955年开始使用灭活疫苗和1959年推广使用口服活疫苗以来,脊髓灰质炎在世界上得到了有效的控制,有些国家已经基本消灭。但经验证明,要从世界上消灭此病还不容易。我国从1975年全国脊髓灰质炎予防经验交流会以来,进一步降低了脊髓灰质炎的发病率,缩小了发病地区,取得了新的进展。现将1975～1977年我国脊髓灰质炎发病情况综述于下: 发病情况三年来,全国各地认真贯彻1975年制定的控制和消灭脊髓灰质炎的规划要求,力争提早达到1980及1985年的防病指标。在大力开展爱国卫生运动,做好一般性预

But experience shows that it is not easy to eliminate the disease from the world. Since the National Conference on Prevention and Control of Poliomyelitis in 1975, China has further reduced the incidence of poliomyelitis and narrowed the incidence areas, and made new progress. Now from 1975 to 1977, the incidence of poliomyelitis in our country is summarized as follows: In the three years since the onset of the disease, the planning requirements for controlling and eradicating poliomyelitis developed in 1975 have been conscientiously implemented in all parts of the country in an effort to reach the targets of disease prevention earlier in 1980 and 1985 . We should vigorously carry out the patriotic health campaign and do a good job of general advancement
