目的了解平顶山市健康人群中肠道病毒的隐性感染情况。方法在平顶山市选择手足口病发病率高发地区汝州市,开展健康人群感染状况调查。在2013年采集100例儿童及成人的粪便和咽拭子标本,分4个年龄组,0~3岁、3~7岁、7~16岁、成人组,用实时荧光PCR进行肠道病毒核酸检测。结果合计检测100人次的标本中,阳性21人次,健康人群肠道病毒隐性感染阳性率达21.00%。结论在我市健康人群中肠道病毒隐性感染情况比较普遍。3~7岁儿童为主要感染人群,通常引起手足口病的CA16和EV71亚型的隐性感染在健康人群中较为少见。
Objective To understand the latent infection of enterovirus in healthy population in Pingdingshan City. Methods In Pingdingshan City, we selected Ruzhou, a city with a high prevalence of HFMD, to investigate the status of infection among healthy population. In 2013, 100 cases of feces and throat swabs from children and adults were collected and divided into 4 age groups, 0 to 3 years old, 3 to 7 years old, 7 to 16 years old, adults, and real-time PCR for enterovirus nucleic acid Detection. Results In a total of 100 samples, the positive rate was 21, and the positive rate of enterovirus latent infection in healthy population was 21.00%. Conclusion The prevalence of enterovirus latent infection in healthy people in our city is relatively common. Children aged 3 to 7 years are predominantly affected, and latent infections of CA16 and EV71 subtypes, which commonly cause HFMD, are less common in healthy individuals.
