湖北省1989～1992年脊髓灰质炎疫情分析

湖北省１９８９年～１９９２年４年中，脊髓灰质炎（脊灰）发病１１５２例，１９９０年为流行高峰，共发病９９０例。流行特征为：从地区分布看，平原高于山区，农村高于城市，从季节分布看，发病主要在春夏季节；从年龄分布看，出现年龄偏小现象；流行毒株以Ⅰ型为主。究其原因，是计划免疫工作不落实。１９９２年脊灰发病率大幅度下降，又与强化了免疫工作有关。作者认为，加强疫情快报制度、提高病例随访率、抓好标本及时采集、做好疫情监测工作是加快消灭脊灰步伐的重要举措。

Analysis of Poliomyelitis Epidemic Disease Situation in Hubei Province from 1989 to 1992

Within the four years from 1989 to 1992, there came 1 152 cases of poliomyclitis in Hubei Province, among which 990 cases came in 1990, reaching the peak of epidemic disese. It is characterized by incidences of such disease being higher in plains than in mountain areas, and in countryside than in city from the viewpoint of region distribution, by epidemic diseases occurring mainly in spring and summer from the viewpoint of season, and by ages being younger and Type Ⅰ being the main epidemic infected plants. The reason for it is that the immunity plans haven't been well carried through effectively. In 1992, the incidences of poliomyclitis decreased by a margin,the fact of which had something to do with the immunity work enhanced. the autor supposes that the key way of quickening the step of exterminating the poliomyclitis should be to strengthen the system of quickly reporting the epidemic situation, to augument the work rate of visiting the diseases cases, to reinforce the work rate of collecting specimens immediately and to enhance the work of supervising and controlling the epidemic diseases.
