目的了解襄阳市感染性腹泻的病原学及流行病学特征,为感染性腹泻的有效控制提供科学依据。方法对襄阳市第一人民医院2013年1月—12月就诊的273例门诊和住院腹泻患者的粪便进行病原学和病毒学检测,并对病原菌的病原谱构成、时间分布、人群分布进行统计学分析。结果从273份粪便标本共检出病原体165份,检出率为60.44%,检出肠道致病菌5株,检出率0.18%;检出肠道病毒160份,检出率为58.61%。肠道腺病毒检出率较高;轮状病毒感染有明显季节特征,秋冬季为发病高峰;诺如病毒感染临床症状表现较重。2岁以下年龄组感染率显著高于其他年龄组。结论襄阳市感染性腹泻以病毒性腹泻为主,其中肠道腺病毒和轮状病毒是主要病原,细菌性引起的感染性腹泻检出率较低。应加强对病毒性腹泻,尤其是婴幼儿病毒性腹泻的监测。
Objective To understand the etiological and epidemiological characteristics of infectious diarrhea in Xiangyang and provide a scientific basis for the effective control of infectious diarrhea. Methods 273 cases of outpatients and inpatients with diarrhea admitted to the First People’s Hospital of Xiangyang City in January-December 2013 were tested for etiology and virology, and the pathogenic profiles, time distribution and population distribution of pathogens were analyzed statistically analysis. Results A total of 165 pathogens were detected from 273 stool specimens, with a detection rate of 60.44%. Five strains of enteric pathogens were detected with a detection rate of 0.18%. 160 strains of enteric viruses were detected with a detection rate of 58.61% . Intestinal adenovirus detection rate is higher; rotavirus infection has obvious seasonal features, autumn and winter peak incidence; Norovirus infection clinical manifestations of severe. The infection rate in the age group under 2 years old was significantly higher than that in other age groups. Conclusions Xiangyang infectious diarrhea is mainly caused by viral diarrhea, in which enteric adenovirus and rotavirus are the main pathogens, bacterial infection caused by diarrhea is lower. Viral diarrhea should be strengthened, especially in infants and young children with viral diarrhea monitoring.
