| 摘 要： | 本文应用圆形分布法对淄博市１９７１～１９９５年流脑疫情进行了分析。结果表明，淄博市流脑发病及死亡有明显的季节性特征，其发病高峰期为２月２０日至５月２３日，死亡高峰期为２月２１日至５月７日。流脑多糖体菌苗接种使流脑发病高峰日提前，发病及死亡更趋分散，季节性减弱。随发病率升高流脑发病高峰日明显推迟，季节性增强，发病更趋集中。淄博市流脑发病有其独特的规律。

| Abstract: | An Analysis on the data of epidemic cerebrospinal meningitis from 1971 to 1995 in Zibo by using circle distribution was carried out. The results showed that there were significant season peaks of the morbidity and death rate of this disease.The peak period of morbidity was from Feb.22 to May 23 and peak period of death rate was from Feb 21 to May 7 .Using group A menigococcal polysaccharide vaccine made peak date of onset in advance,the case and death number of patients were more dispersive and no significant season characteristic. The peak date became to delay,season distribution became significant and case number was concentrated when the high morbidity appeared. Those characteristics of epidemic cerebrospinal meningitis were special in Zibo |
