摘要
目的分析贺州市手足口病流行病学特征,为防控决策提供科学依据。方法收集2008年5月-2010年5月贺州市手足口病疫情和实验室检测资料,统计分析3年同期的发病率、发病人群特征、病例地域分布特征、流行消长特征和实验室检测结果。结果 2008年5月-2010年5月,发病逐年上升。3年病例分别覆盖81.36%、81.36%和93.22%的乡镇。农村发病占总病例数的64.22%。3年发病高峰期徘徊在3～7月份。4 285例手足口病病例中,以5岁以下儿童为主,占93.23%。发病男性高于女性,为1.69～1.84:1。散居儿童发病(含聚集性病例)明显高于托幼儿童,为3.64～5.32:1。实验室标本检测以EV71阳性为主,占24.10%;CoxA16阳性16例,占19.28%。结论 3年发病呈逐年上升趋势,农村发病比重大于城镇,防控任务依然艰巨。疫情高发地区次年发病会有下降,而发病率低的地区次年发病会有所上升。3～7月为流行高峰。散居儿童发病明显高于托幼儿童,防控难度增大。男性发病高于女性,手足口病发病是否具有性别易感性,有待进一步研究。贺州市手足口病流行的优势毒株为EV71。
Objective To analyze the epidemiological features of hand-foot-mouth disease in Hezhou city of GuangXi for providing scientific bases for its preventive decision-making.Methods The status of the hand-foot-mouth disease and laboratory examination material were collected in Hezhou city from May,2008 to May,2010.The morbidity rate,distribution of the disease in the three years,and the results of relative laboratory test were analyzed.Results The morbidity rate of the disease has increased in the three years.The cases of the disease covered 81.36%、81.36% and 93.22% of villages and towns respectively in these three years and 64.22% of the cases were from rural area.The peak incidence was in March to July.93.23% of the cases were among children aged under five years in total of 4285 cases in Hezhou.The morbidity rate in male is higher than in female which is 1.69-1.84：1.The morbidity rate in scattered children（included aggregation cases） is higher than in nursery and kindergarten children which is 3.64-5.32：1.24.10% of samples were tested with EV71 positive in laboratory and 16 cases with Cox A16 positive which occupied 19.28%.Conclusion The morbidity has increased in the three years,and with higher rate in rural area than in town and city.The morbidity rate in high incidence area would decrease and in low incidence area would increase in next year.The task is still arduous for scattered children with higher incidence than nursery and kindergarten children.
