目的探讨山东省2008至2014年手足口病发病的季节性分布特征。方法选取山东省法定传染病报告系统中2008至2014年手足口病监测数据,进行季节性特征分析。结果山东省2008至2014年手足口病年均增长率为22.96%,发病率从35.02/10万增长到121.01/10万。总报告例数中,5~7月报告的病例数占总病例数的51.29%(188 564/367 655)。集中度M值为0.42,手足口病有一定的季节性;圆形分布γ=0.42,珔α=185.196°(110.216°,260.176°),P<0.01,即山东省手足口病发病高峰日为6月8日,流行高峰期为3月22日至8月24日。山东省2008至2014年各年的平均角之间差异有统计学意义(F=2 401.14,P<0.01),即各年手足口病高峰日不同。M值和γ值呈高度相关(r=1.000,P<0.01)。结论山东省2008~2014年手足口病发病有一定的季节性特征,3~8月为该病的流行高峰期,各年度流行期持续时间不同。
Objective To investigate the seasonal distribution of HFMD in Shandong Province from 2008 to 2014. Methods The surveillance data of HFMD from 2008 to 2014 in the reporting system of legal infectious diseases in Shandong Province were selected for seasonal characteristics analysis. Results The average annual growth rate of hand-foot-mouth disease in Shandong Province from 2008 to 2014 was 22.96%, the incidence increased from 35.02 / 100000 to 121.01 / 100000. Among the total reported cases, the reported cases from May to July accounted for 51.29% (188 564/367 655) of the total number of cases. Concentration M was 0.42, hand-foot-mouth disease had a certain seasonal; circular distribution γ = 0.42, 珔 α = 185.196 ° (110.216 °, 260.176 °), P <0.01, that is, June 8, the peak period of March 22 to August 24. There was a significant difference between the average angles in Shandong province from 2008 to 2014 (F = 2 401.14, P <0.01), that is, the peak days of hand-foot-mouth disease were different in each year. M and γ values were highly correlated (r = 1.000, P <0.01). Conclusion The incidence of hand, foot and mouth disease in Shandong Province from 2008 to 2014 has certain seasonal characteristics. The peak period of the disease is from March to August, and the duration of epidemic period is different in each year.
