2015-2018年揭阳市手足口病病原学监测分析

Etiology surveillance of hand-foot-mouth disease in Jieyang, 2015-2018

目的掌握2015-2018年揭阳市手足口病病原学特征及流行规律,为其防控提供科学依据。方法2015-2018年揭阳市手足口病监测哨点医院采集手足口病普通临床病例标本,进行肠道病毒检测。结果共采集手足口病标本1008份,检出阳性标本703份,阳性率为69.74%,病例主要集中在5岁以下儿童。2015-2018年手足口病阳性率逐年下降,其中以EV71阳性率下降最明显。2015、2016及2018年手足口病均以其他肠道病毒为主,2017年手足口病以CVA6为主。结论2015-2018年揭阳市手足口病流行的季节性及人群特征明显,EV71所占比例下降较快,应继续监测,对于手足口病的防控具有重大的意义。

Objective To explore the epidemic pattern of hand-foot-mouth disease(HFMD)pathogen in Jieyang from 2015 to2018,so as to provide scientific evidence and technical support for the further prevention and control of this disease.Methods The samples from common clinical cases of HFMD were collected in sentinel hospitals,and enterovirus was tested in Jieyang from 2015 to 2018.Results Out of total 1008 samples collected,703 were identified as HFMD positive and The positive rate was 69.74%.Most of the positive cases were under 5 years old.The positive rate of HFMD decreased year by year,and the positive rate of EV71 decreased most significantly.The other enteroviruses were the major pathogens in 2015,2016 and 2018,while CVA6 was predominant in 2017.Conclusion The seasonality and population characteristics of HFMD were obvious in Jieyang from 2015 to 2018.The proportion of EV71 decreased rapidly,and monitoring should be continued,which is of great significance for the prevention and control of HFMD.
