Abstract
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）是全球爆发急性肠胃炎的主要原因。诺如病毒是一种非显性病毒，分为 10 个基因组，其中基因组 I (GI)、II (GII)、IV (GIV)、VIII (GVIII) 和 IX (GIX) 是感染人类的病毒。本文描述了在一所幼儿园爆发的两起急性肠胃炎（A 和 B）。第一次爆发（A）发生在 2018 年 11 月，第二次爆发（B）发生在 2020 年 2 月。为研究这两起疫情，对病毒和细菌病原体进行了检测。此外，还对疫情进行了流行病学调查。在分析的幼儿园儿童和成人的粪便和呕吐物样本中，分别检测到 A 次和 B 次疫情中的 NoV GII.4 [P16] Sydney 2012 和 NoV GI.3 [P13]。由于阿根廷对急性肠胃炎疫情的研究估计不足，因此有必要制定预防、研究和控制方案，并改进我国的疫情通报系统。
