新疆流脑第四次周期性流行特征

Fourth Periodic Epidemic Characteristics of Cerebro-spinal Meningitis in Xiajiang

本文在回顾37年(1951～1987)流脑常规疫情报告资料的基础上,着重对全区6年(1982～1987)流行资料和51县市5年(1983～1987)城乡专题调查结果进行了分层分析。37年新疆流脑流行同全国波动规律一致,显示了新疆流脑流行同全国的关系。连续4年(1984～1987)新疆流脑发病率高出全国水平,打破了既往一直低于全国的流行规律。流行主要先从北(包括东疆)开始,具有先城镇后农村、先北疆后南疆传播的规律。5年病死率为9.26,比全国(一般5％)高,并且农村(9.97％)高于城镇(6.15％),尤以南疆农村为甚(10.45％)。

To understand epidemic characteristics of the disease an investigation was made from the whole region over 1982～1987 and 51 counties and cities over 1983～1987. The prevalent conditions of entire region were also compared with those of the nation. It is suggested that CSM epidemics were related to Xinjiang's and whole countr's epidemics regulation from 1984 to 1987. The Xinji ang's CSM morbidities were higher than those of whole nation, which broken out its lower epidemic state before. The CSM epidemic first started at urban area of the north part in Xiniiang, then to the rural and the south. From 1983 to 1987 the disease mortality (9.26％)was higher than that (about 5％)of the whole country. The rural (9.97％) was higher than that (6.15％)of the urban also, especially the south rural was as high as 10.45％.
