    Abstract:
    Rotavirus and norovirus are well-known causes of viral infectious diarrhea. There are few reports on diarrhea caused by other viruses in Korea, although cases of gastroenteritis attributable to other viruses are increasing worldwide. The aims of this study were to detect various causes of viral diarrhea and to investigate their prevalence. A total of 801 fecal specimens submitted to a clinical microbiology laboratory for the detection of diarrheal viruses were included. We sought to detect rotavirus A/B/C, adenovirus, astrovirus, norovirus GI/GII, sapovirus, Aichi virus, human parechovirus, enterovirus, human cosavirus, human bocavirus, and Saffold virus using multiplex reverse transcription polymerase chain reaction (RT-PCR). At least one diarrheal virus was detected in 223 (27.8%) fecal specimens. Among them, two viruses were detected in 11 specimens. Rotavirus A was most common (17.1%; N = 137), followed by norovirus GII (5.0%; N = 40), enterovirus (4.2%; N = 34), adenovirus (1.0%; N = 8), astrovirus (1.0%; N = 8), human parechovirus (0.6%; N = 5), and human bocavirus (0.2%; N = 2). Rotaviruses B and C, norovirus GI, sapovirus, Aichi virus, human cosavirus, and Saffold virus were not detected. We confirmed that various diarrheal viruses can be detected in fecal specimens. We must consider the possibility of viruses other than rotavirus and norovirus being present in cases of diarrhea.
