摘要
目的了解攀枝花市细菌性痢疾发生的高峰日及高峰期,掌握发病动态,提前做好监测,采取预防控制措施。方法采用圆形分布法对攀枝花市2005-2013年细菌性痢疾的季节分布特征进行分析。结果攀枝花市细菌性痢疾全年均有发病,5～6月份达高峰,11～12月份最低;2005-2013年细菌性痢疾发病逐年下降（趋势χ2=4 602.51,P〈0.01）;发病存在明显的高峰日和高峰期（P〈0.01）,总高峰日在6月23日,总高峰期为3月12日～10月3日,各年发病高峰日不相同或不全相同（F=44.67,P〈0.01）。结论攀枝花市细菌性痢疾发病有明显的季节性分布特征,3～10月为该病的流行高峰期;总体发病逐年下降,季节性有提前趋势,建议应根据其流行特点的变化适时采取和调整防控策略。
Objective To investigate the peak day and the crest time in the occurrence of bacillary dysentery in Panzhihua city and master the prevalent trend in advance to work on supervision and take precautions. Methods Circular distribution method was used to analyze seasonal distribution characteristics of bacillary dysentery from2005 to 2013 in Panzhihua city. Results Bacillary dysentery in Panzhihua city occurred in each month all the year,arriving the peak time in May and June. The disease nu mber was in lower level from November and December. The incidence of bacillary dysentery decreased annually from 2005 to 2013（ trend χ2= 4602. 51,P 〈0. 01）. There were obvious peak day and crest time（ P 〈0. 01）. The peak day through year was 23 rd June,and the crest time was from 12 th March to 3rd October. The peak day of the incidence of bacillary dysentery in each year was different or partly different（ F = 44. 67,P〈0. 01）. Conclusion There is an obvious seasonality of the incidence of bacillary dysentery in Panzhihua city,and the crest time is from March to October. In general,the incidence of bacillary dysentery decreased year by year,and the trend of the seasonality is in advance. Prevention and control strategy should be adopted and adjusted according timely to the change of epidemic characteristics of bacillary dysentery.
