Norovirus (NoV) is the leading cause of outbreaks of acute gastroenteritis worldwide. These are non-enveloped viruses that are classified into 10 genogroups, of which genogroup I (GI), II (GII), IV (GIV), VIII (GVIII), and IX (GIX) are the ones that infect humans. Two outbreaks (A and B) of acute gastroenteritis that occurred in a nursery school are described. The first outbreak (A) occurred in November 2018, and the second (B) in February 2020. The detection of viral and bacterial pathogens was performed to study both outbreaks. Additionally, an epidemiological investigation of the outbreaks was conducted. In the analyzed fecal and vomit samples from both children and adults in the nursery school, NoV GII.4 [P16] Sydney 2012 and NoV GI.3 [P13] were detected in outbreaks A and B, respectively. Since the study of acute gastroenteritis outbreaks is underestimated in Argentina, it is necessary to design prevention, study, and control protocols, as well as to improve the outbreak notification system in our country.
诺如病毒（NoV）是全球急性胃肠炎暴发的主要原因。这些是无包膜病毒，分为10个基因群，其中基因群I（GI）、II（GII）、IV（GIV）、VIII（GVIII）和IX（GIX）可感染人类。本文描述了一所幼儿园发生的两起急性胃肠炎暴发事件（A和B）。第一次暴发（A）发生在2018年11月，第二次（B）发生在2020年2月。为研究这两起暴发事件，对病毒和细菌病原体进行了检测。此外，还对暴发事件进行了流行病学调查。在分析的该幼儿园儿童和成人的粪便及呕吐物样本中，分别在暴发事件A和B中检测到了诺如病毒GII.4 [P16] 悉尼2012株和诺如病毒GI.3 [P13]。由于阿根廷对急性胃肠炎暴发事件的研究被低估，因此有必要设计预防、研究和控制方案，以及改进我国的暴发事件通报系统。
