Several viruses have been associated with acute gastroenteritis (AGE), and group A rotavirus (RVA) and norovirus (NoV) are the most prevalent. This study aimed to assess their prevalence among children hospitalised for diarrhoea during a three-year surveillance study. From May 2008-April 2011, overall positivity rates of 21.6% (628/2904) and 35.4% (171/483) were observed for RVA and NoV, respectively. The seasonality observed indicated distinct patterns when both viruses were compared. This finding may explain why hospitalisation for AGE remains constant throughout the year. Continuous AGE monitoring is needed to better assess the patterns of infection.
几种病毒与急性胃肠炎（AGE）有关，其中A组轮状病毒（RVA）和诺如病毒（NoV）最为常见。本研究旨在评估在一项为期三年的监测研究中，因腹泻住院的儿童中这些病毒的流行情况。2008年5月至2011年4月期间，RVA和NoV的总体阳性率分别为21.6%（628/2904）和35.4%（171/483）。观察到的季节性表明，两种病毒相比较时存在明显差异。这一发现可能解释了为什么AGE住院病例全年保持稳定。需要持续监测AGE，以更好地评估感染模式。
