应用因子分析理论，结合随州市８年来的流脑监测资料，对影响流脑流行的１２个因素进行了研究。结果表明，影响流脑流行的前六位因素是：人群流脑菌Ｂ群、Ａ群带菌率、一月份相对湿度、一月份发病率、流行前期流脑接种率和人群抗体平均滴度。尽管当前流脑发病以散发为主，但影响流脑流行的因素并未完全消失，继续广泛使用流脑Ａ群多糖菌苗，加强对流动人口及重点地区人群的监测工作仍具有重要意义

Based on a 8 year surveillance data,a factor analysis theory was used to analyze the 12 risk factors influencing the epidemicity of epidemic cerebrospinal meningitis.The results showed that the first sixth risk factors were the rate of carrying meningococci A and B in the population,relative air humidity in January,morbidity rate in January,vaccination rate before epidemic,and the titre of antibody.Although the incidences of epidemic cerebrospinal meningitis are scattered,the risk factors influencing the epidemicity did not disappear.It is important to use meningococci A vaccine continuously and widely to strengthen the surveillance among migrated population and population at high risk.
