Rotavirus diarrhea is often referred as "winter diarrheal disease" as it causes nearly 50% of the pediatric hospitalizations during winter season. This study was done with the objective of bringing out the epidemiological nexus of rotavirus cases with different seasonal parameters like maximum, minimum temperature, humidity, and average rainfall. This prospective observational study was conducted in a tertiary care teaching hospital of Eastern India from February 2016 to December 2018. Data on daily maximum and minimum temperature, relative humidity, and rainfall were collected. Of 964 children admitted, 768 stool samples were collected for rotavirus assay. A total of 222 children (29%) were positive. The maximum, minimum temperature, average rainfall, and average humidity of 83.4 mm, 79.2%, 28.1, and 21.9, respectively, were significantly associated with positive rotaviral cases. The incidence of rotavirus positivity cases was found to be inversely associated with average temperature, humidity, and rainfall. The knowledge about the seasonal pattern in a particular geographical area would help in the reallocation of hospital services (staff and bed) to tackle the epidemic or emergency situations resulting from clustering of cases.
轮状病毒腹泻常被称为“冬季腹泻病”，因为它导致了冬季近50%的儿科住院病例。本研究旨在揭示轮状病毒病例与最高气温、最低气温、湿度和平均降雨量等不同季节参数之间的流行病学联系。这项前瞻性观察研究于2016年2月至2018年12月在印度东部的一家三级护理教学医院进行。收集了每日最高气温、最低气温、相对湿度和降雨量的数据。在964名入院儿童中，采集了768份粪便样本进行轮状病毒检测。共有222名儿童（29%）呈阳性。最高气温、最低气温、平均降雨量和平均湿度分别为83.4毫米、79.2%、28.1和21.9，与轮状病毒阳性病例显著相关。发现轮状病毒阳性病例的发生率与平均气温、湿度和降雨量呈负相关。了解特定地理区域的季节性模式将有助于重新分配医院服务（人员和床位），以应对病例聚集导致的疫情或紧急情况。
