目的分析江苏省1997～2009年度疟疾发病的季节性,研究江苏省疟疾流行特征,为积极防治疟疾流行提供参考依据。方法收集江苏省疾病监测信息报告网络直报管理系统中间日疟疫情资料,按月统计间日疟发病数,用圆形分布法分析江苏省间日疟的发病高峰日和高峰期。结果江苏省间日疟发病具有明显的季节性(P<0.01),各年份发病高峰日不全相同(P<0.01),平均发病高峰日为8月5日,发病高峰日最早出现在1997年的7月14日,最晚出现在2006年的9月1日,二者之间相差了49d。结论江苏省间日疟存在明显的季节高峰,其发病高峰日多集中在8月份;间日疟流行高峰期延长与全球气候变暖之间是否存在关联还有待商榷。
Objective To analyze the seasonality of malaria incidence in Jiangsu Province from 1997 to 2009 and study the characteristics of malaria in Jiangsu Province so as to provide reference for the prevention and control of malaria epidemic. Methods The data of Vasilovia malaria in the network reporting system of Disease Surveillance Information Report of Jiangsu Province were collected. The incidence of P. vivax was calculated by monthly statistics. The distribution and distribution of P. vivax in Jiangsu Province was analyzed. Results The incidence of Plasmodium vivax in Jiangsu Province was obviously seasonal (P <0.01). The peak incidence was not the same in all years (P <0.01). The average incidence peak day was August 5, and the peak incidence peak appeared in 1997 July 14, the latest appeared on September 1, 2006, the difference between the two 49d. Conclusions There is a clear seasonal peak in P. vivax in Jiangsu Province. Most of the peak days are concentrated in August. Whether the relationship between the prolongation of P. vivax and global warming is yet to be discussed.
