Gastroenteritis with diarrhea is one of the most infectious diseases in the world following respiratory infections. Notably, diarrhea-causing viruses (DVs) cause more than 70% of such cases. In this study, 3,065 stool specimens from patients with diarrhea (median age, 1.1 years; range, 0.0-91.1 years), who were admitted to the DanKook University Hospital, were examined using multiplex reverse transcription PCR (mRT-PCR). The target viruses were astrovirus (AstV), enteric adenovirus (EAdV), group A rotavirus (RotV), norovirus GI (NoV-GI), and norovirus GII (NoV-GII). The mRT-PCR results were analyzed based on various factors such as seasonality, age, presence of co-infection, and analyzed trends. The detection rate of the DVs during the study period was found to be 30.8% (n = 943/3,065). When the detection rate was analyzed monthly, the DV detection rate was found to be highest between December to January. Of the detected DVs, NoV-GII was the most common, accounting for 45.5% of the detected viruses (n = 446/980). Notably, 86.5% (n = 848/980) of the pathogens were detected in individuals who were less than 5 years of age. During the study period, NoV-GII and RotV showed alternating trends. In addition, both the number and rate of co-infections increased.

[18], and reported the long-term (2010−2018) infection pattern of DVs in Cheonan province. The purpose of this study was to identify the DVs infection trends in the Cheonan area of Korea and to use these trends as baseline data for the prevention of socioeconomic damage caused by gastroenteritis with diarrhea.
However, there have been a number of studies that have examined trends over a short period of 2−3 years or studies on long-term trends for single DVs. The results of this study will help to understand the trend of DVs and will be aid in the prevention and treatment of gastroenteritis with diarrhea caused by DVs.
