Identified as a potential reference pathogen by the WHO Guidelines for Drinking-Water Quality, Rotavirus (RV) is among the main enteric viruses that cause waterborne diseases. The aim of this study was to identify and correlate the presence of RV in collective and individual water sources of rural communities in the state of Goiás, within the seasons in which the collections were made (rainy and dry seasons). For this, 86 water samples in the dry period and 160 samples in the rainy period were collected. Concentration of water samples, extraction of viral genetic material and molecular tests were performed. When analyzing the presence of RV in the samples, taking into consideration the period studied, RV was found to be more prevalent in the dry season (54.7%) than in the rainy season (20%), showing a strong statistical association with the dry season (-value < 0.001). The presence of pathogenic microorganisms in water is a public risk issue, enabling the emergence of outbreaks, endemics and epidemics. In the present research, there was an association between the presence of Rotavirus and the dry period of the year when compared to the rainy period.
世界卫生组织《饮用水水质准则》将轮状病毒（RV）确定为潜在的参考病原体，它是引起水传播疾病的主要肠道病毒之一。本研究旨在鉴定和关联戈亚斯州农村社区集体和个人水源中 RV 的存在，并对收集季节（雨季和旱季）进行分析。为此，在旱季采集了 86 份水样，在雨季采集了 160 份水样。对水样进行浓缩、提取病毒遗传物质并进行分子检测。分析样本中 RV 的存在情况时，考虑到所研究的时期，RV 在旱季（54.7%）比雨季（20%）更为普遍，与旱季存在很强的统计学关联（-值<0.001）。水中致病性微生物的存在是一个公共风险问题，会导致疫情的爆发、流行和蔓延。在本研究中，与雨季相比，轮状病毒的存在与旱季存在关联。
