目的探讨北京市密云县病毒性腹泻的病原学特点,为病毒性腹泻的防控提供参考依据。方法 2011年4月—2012年3月采集在密云县医院、中医院和妇幼保健院肠道门诊就诊的腹泻患者粪便标本,进行病原学监测。结果 133份粪便标本实验室检测结果显示,杯状病毒的阳性检出率最高,为16.54%;其次为轮状病毒阳性率,为7.52%。对上述2种病毒与感染者性别、年龄以及发病季节的比较发现,除轮状病毒和杯状病毒与发病季节差异有统计学意义(P<0.05)外,其余均无统计学意义。结论轮状病毒和杯状病毒是引起密云县病毒性腹泻的主要病原体,应进一步开展病毒性腹泻监测和阳性毒株分型工作。
Objective To explore the etiological characteristics of viral diarrhea in Miyun County, Beijing, and provide reference for the prevention and control of viral diarrhea. Methods From April 2011 to March 2012, stool specimens from diarrhea patients in the enteric clinics of Miyun County Hospital, Chinese Medicine Hospital and MCH Hospital were collected and pathogenically monitored. Results 133 laboratory tests of stool specimens showed that the positive rate of calicivirus was 16.54%, followed by that of rotavirus (7.52%). The comparison of the sex, age and season of onset of the two viruses with those of the infected persons showed that there was no statistical significance except for the difference between rotavirus and calicivirus and the onset season (P <0.05). Conclusions Rotavirus and calicivirus are the major pathogens causing viral diarrhea in Miyun County. Viral diarrhea monitoring and typing of positive strains should be further carried out.
