Diarrhea is one of the leading causes of death among children, especially in the age under 5, but few studies are available on viral diarrhea in Shenyang. To understand the infection status and the relevant epidemiological characteristics of viral diarrhea and to fill gaps of the distribution of viruses across Shenyang in children under the age of 5 with diarrhea, from 2018 to 2020, stool specimens of children with diarrhea aged 0-59 months and surveillance data were collected in Sentinel Hospital of Shenyang. Specimens were then tested to determine the type of viruses, the seasonal and spatial patterns for major viruses were determined. Viruses were identified in 47.9% of the 897 samples from children with diarrhea. The main viruses of stool samples were rotavirus (16.9%, predominant type G9P[8]), calicivirus (14.7%), adenovirus (11.8%), and astrovirus (4.5%). Viral infections were mainly detected in the age of 0-12 months. In the area of Shenyang, Huanggu had the most cases (198, 22.1%), followed by Dadong (137, 15.3%) and Hunnan (135, 15.1%). The positive rate of viruses varied among patients of different ages, seasons, and regions. Public health entities and the government should develop corresponding measures for different age groups, seasons, and regions.
腹泻是导致儿童死亡的主要原因之一，尤其是 5 岁以下儿童，但关于沈阳病毒性腹泻的研究较少。为了解病毒性腹泻的感染状况及相关流行病学特征，填补沈阳市 5 岁以下腹泻儿童病毒分布的空白，2018 年至 2020 年，在沈阳市哨点医院采集 0-59 月龄腹泻患儿的粪便标本和监测数据。检测标本以确定病毒类型，确定主要病毒的季节性和空间模式。在 897 份腹泻儿童粪便样本中，有 47.9%的样本检测出病毒。粪便样本的主要病毒为轮状病毒（16.9%，主要型别为 G9P[8]）、杯状病毒（14.7%）、腺病毒（11.8%）和星状病毒（4.5%）。病毒感染主要发生在 0-12 月龄。在沈阳地区，黄姑区的病例最多（198 例，22.1%），其次是大东区（137 例，15.3%）和浑南区（135 例，15.1%）。不同年龄、季节和地区的患者病毒阳性率不同。公共卫生实体和政府应针对不同年龄组、季节和地区制定相应措施。
