摘　　要：目的分析深圳市龙岗区手足口病暴发疫情的流行病学特征,为制定预防控制策略提供科学依据。方法采用描述性流行病学方法,率的比较采用χ2检验。结果 2005-2014年期间,龙岗区一共报告141宗手足口病暴发疫情,主要发生在托幼机构127宗(90.07%)。自2008年起,每年首宗暴发疫情较同年疫情高峰提前中位时间2个月。疫情送检不同样本粪便和肛拭子的检出率差异无统计学意义(χ2=20.286,P=0.319),但病后3 d内采样阳性检出率较≥4 d高,差异有统计学意义(χ2=5.766,P=0.016)。结论托幼机构为手足口病疫情防控的重点场所,为提高样品的阳性检出率,应尽量采集发病3 d内的标本。Objective To analyze the epidemiological characteristics of outbreaks of Hand-foot-mouth Disease in Longgang district of Shenzhen City, and provide scientific evidence for HFMD prevention and control. Method Descriptive epidemiological method was used for the epidemiological analysis and,and the comparisons of rate used ？ 2 test was used for comparison. Result There were 141 outbreak cases of HFMD reported during 2005 ~2014 in Longgang district.90.07% cases wereoccurred in kindergartens. The first outbreak case in each year was always observed 2 months（median time） earlier than the peak in the same year since 2008. The positive detection rates from stool, anal swab, throat swab and blister fluid samples were not statistically significant（χ^2=20.286,P =0.319）,but the samples collected ≤3 d after illness were significantly had a higher positive detection rates than ≥4d（χ^2=5.766,P =0.016）. Conclusion The HE kindergartens will should be the key place of the epidemic prevention and control for the outbreaks of HFMD. Samples should be collected ≤3 d after illness in order to improve the positive detection rate.
