目的分析礼泉县2009—2011年手足口病发病情况,探讨流行规律,为制定手足口病防控策略提供科学依据。方法采用描述性流行病学方法对礼泉县2009—2011年手足口病疫情资料进行分析。结果 2009—2011年礼泉县共报告手足口病894例,年均发病率为62.55/10万,各年发病率分别为48.80/10万(239/489 715)、102.08/10万(502/491 761)和34.17/10万(153/447 771),差异有统计学意义(P<0.01)。发病有明显的季节高峰,主要集中4—7月,共报告721例,占病例总数的80.65%。发病年龄主要集中在5岁以下年龄组,占发病总数的91.50%(818/894)。男性600例,女性294例,男女性别比为2.04∶1;病例职业以散居儿童为主,占发病数的85.79%(767/894)。结论礼泉县2009—2011年手足口病发病具有明显的季节性特征,发病以5岁以下散居儿童为主,今后应在流行季节加强对重点人群的监管和防控,加强疫情监测,减少发病和死亡。
Objective To analyze the incidence of hand-foot-mouth disease in Liquan County from 2009 to 2011, and to explore the prevailing laws to provide a scientific basis for the prevention and control of hand-foot-mouth disease. Methods Descriptive epidemiological methods were used to analyze the epidemic data of HFMD in Liquan County from 2009 to 2011. Results A total of 894 HFMD cases were reported in Liquan County from 2009 to 2011, with an average annual incidence of 62.55 / 100 000. The annual incidence rates were 48.80 / lakh (239/489 715) and 102.08 / lakh (502 / 491 761) and 34.17 / 100000 (153/447 771), the difference was statistically significant (P <0.01). The onset of a significant seasonal peak, mainly in April-July, a total of 721 reported cases, accounting for 80.65% of the total number of cases. The age of onset mainly concentrated in the age group of 5 years old, accounting for 91.50% (818/894) of the total. There were 600 males and 294 females with a sex ratio of 2.04:1. The majority of cases were scattered children, accounting for 85.79% (767/894) of the cases. Conclusion The incidence of hand, foot and mouth disease in Liquan County is obviously seasonal in 2009-2011. The incidence is mainly for children under 5 years of age.
