目的了解2011年郧县手足口病(HFMD)病原分布特征。方法用描述性流行病学方法对郧县2011年手足口病实验室诊断病例进行分析,用Excel及SPSS17.0进行统计分析。结果 2011年郧县共报告手足口实验室诊断病例118例,CoxA16型74例(62.71%)、EV71型30例(25.42%)、其他肠道病毒14例(11.86%)。1～12月CoxA16型构成每月均大于其他2型;CoxA16型每月均有分布,4～6月居多(56.76%);EV71型分布在4～9月,4～6月居多(90.00%);其他肠道病毒分布在4～6月(100.00%);EV71型4～6月构成比大于CoxA16型,差异有统计学意义(χ2=4.551,P=0.033)。3种型别均为散居儿童为主;除4岁年龄组外,其余年龄组CoxA16型均为优势型别。结论 2011年郧县手足口病以Cox-A16型为优势流行型别,且在时间和年龄分布上表现为优势构成,EV71型4～6月分布较多,应重点加强监测。
Objective To understand the distribution of pathogens of HFMD in Yun County in 2011. Methods Descriptive epidemiological methods were used to analyze laboratory diagnosis of hand, foot and mouth disease in Yunxian County in 2011. The data were analyzed by Excel and SPSS17.0. Results In 2011, 118 cases of hand, foot and mouth laboratory diagnosed were reported in Yunxian County, including 74 cases of CoxA16 type (62.71%), 30 cases of EV71 type (25.42%) and 14 cases of other enteroviruses (11.86%). From January to December, the constitution of CoxA16 was larger than that of other 2 types every month; CoxA16 was distributed monthly, from April to June (56.76%); EV71 was from April to September, mostly from April to June (90.00% ). The distribution of other enteroviruses was from April to June (100.00%). The EV71 type from April to June was more than that of CoxA16 type (χ2 = 4.551, P = 0.033). The three types were mainly diaspora; except for the 4-year-old group, the other age groups were predominant CoxA16 type. Conclusion In 2011, Yunxian hand-foot-mouth disease predominated with Cox-A16 type, and its distribution was superior in time and age distribution. There was a large distribution of EV71 in April-June, and monitoring should be strengthened.
