摘要
目的了解2005-2010年浦东新区细菌性痢疾发病情况,分析细菌性痢疾发病的季节性规律,并探讨发病季节性对细菌性痢疾发病率变化的影响。方法采用圆形分布法,比较和分析发病率不同的各时期细菌性痢疾发病高峰日和高峰期的情况。结果 2005-2010年浦东新区细菌性痢疾发病高峰日分别为9月10日、9月8日、8月18日、8月30日、7月20日和8月7日;高峰期分别为127 d、130 d、170 d、142 d、169 d和193 d;高峰期可受最高月病例构成的影响发生相应的改变。结论细菌性痢疾的季节性和发病高峰不随细菌性痢疾发病率改变而变动;痢疾发病高峰与蝇类季节消长态势相吻合。圆形分布法分析单峰型有季节特征的细菌性痢疾的发病高峰特征,简明扼要、描述直观。
Objective To investigate the seasonal pr evalence of bacillary dysentery from 2005 to 2010 in Pudong New Area.Methods Circular distribution method was used to analyze influence of the different morbidity of bacillary dysentery on peaks.Results The highest peaks of incidence of bacillary dysentery from 2005 to 2010 were September 10,September 8,August 18,August 30,July 20 and August 7;with the duration of 127 d,130 d,170 d,142 d,169 d and 193 d,respectively.Conclusions The seasonal character and peak incidence of bacillary dysentery do not vary with the change of its morbidity.As a matter of fact,peak incidence of dysentery always tallies with the seasonal prevalence of flies.Simple calculation and intuitive description are such advantages of circular distribution method in analyzing the seasonal variation of diseases with single peak and cyclic change.
