目的了解2006～2010年泰安市手足口病流行病学特征。方法应用描述流行病学方法对泰安市2006～2010年手足口病疫情资料进行分析。结果 2006～2010年泰安市累计报告手足口病19 213例,死亡4例,年均发病率为68.95/10万,死亡率为0.01/10万,病死率为0.02%;发病呈逐年上升趋势,其中2006年623例,发病率为11.29/10万;2010年8 337例,发病率为147.67/10万。手足口病每年5～8月发病较多,个别年份10～12月可再次发生流行,并可使次年手足口病流行提前;经济发达及沿交通干线分布的区域为手足口病的高发地区;手足口病发病以散居儿童为主,占全部报告病例的69.47%,1～2岁发病率最高,报告病例占全部报告病例的46.07%;2008和2009年以EV71为优势流行毒株,2010年以CA16为优势流行株。结论秋冬流行峰的出现预示来年手足口病流行将提前,EV71与CA16交替流行使手足口病疫情居高不下。
Objective To understand the epidemiological characteristics of HFMD in Tai’an from 2006 to 2010. Methods Epidemiological methods were used to analyze the data of HFMD in Tai’an from 2006 to 2010. Results A total of 19 213 hand-foot-mouth disease and 4 deaths were reported in Tai’an City from 2006 to 2010. The average annual incidence was 68.95 / 100 000, with a mortality rate of 0.01 / 100,000 and a case fatality rate of 0.02%. The incidence increased year by year, Including 623 cases in 2006, the incidence was 11.29 / 100,000; 2010 8 337 cases, the incidence was 147.67 / 100,000. Hand-foot-mouth disease occurs more frequently from May to August every year, and the epidemic may occur again from October to December in individual years, and may make the epidemic of hand-foot-mouth disease advance in the next year ahead. The economically developed areas along the main arterial routes are areas with high incidence of hand-foot-mouth disease . The incidence of hand-foot-mouth disease was mainly for scattered children, accounting for 69.47% of all the reported cases, the highest incidence was found between 1 and 2 years old. The reported cases accounted for 46.07% of the total reported cases. EV71 was the predominant epidemic strain in 2008 and 2009, 2010 CA16 is the dominant epidemic in years. Conclusions The appearance of the peak of autumn and winter indicates that the epidemic of HFMD will advance in the coming year. The prevalence of HFMD in EV71 and CA16 is still high.
