Norovirus outbreaks in long-term care facilities. Catalonia, 2017-2018 CSV Version

Dataset about Norovirus outbreaks in Long-Term Care Facilities (LTCF) reported between January 2017 and December 2018 was made in Catalonia, a region in North-western Spain with a population of 7,496,276 in January 2017. Norovirus outbreaks occurring in LTCF confirmed by RTqPCR were included. The numbers of residents and staff, the capacity of the centre and whether transmission was person-to-person or by a common vehicle were collected. A survey was designed for all exposed (affected and unaffected) persons including sociodemographic data, the degree of dependence (estimated using the Barthel index), the medical history, the date and time of symptom onset and the symptoms presented. For staff, information on the type of work was collected. Stool samples were collected to identify the cause of the outbreak. Norovirus was tested for using quantitative reverse transcription PCR (RTqPCR) and identifying the genogroup detected, as described above17. The semi-quantitative value given by the RTqPCR cycle of quantification (Cq) was used to measure the viral load in samples positive for norovirus. Stool samples were obtained from both symptomatic and asymptomatic staff and residents and, in outbreaks where a foodborne transmission was suspected, from food handlers.本数据集涵盖2017年1月至2018年12月间西班牙西北部加泰罗尼亚地区上报的长期护理机构（Long-Term Care Facilities, LTCF）诺如病毒暴发事件。该地区2017年1月常住人口为7496276人。本数据集纳入经实时荧光定量逆转录聚合酶链反应（RTqPCR）确认的长期护理机构诺如病毒暴发事件。研究收集了机构内居住者与工作人员数量、机构承载容量，以及传播途径为人际传播还是共同媒介传播相关数据。研究针对所有暴露人群（包括发病与未发病人员）设计调查问卷，内容涵盖社会人口学数据、日常生活活动依赖程度（采用Barthel指数评估）、病史、症状发作的日期与时间，以及所出现的症状。针对工作人员，额外收集了其工作类型相关信息。研究收集粪便样本以明确暴发病因，采用RTqPCR检测诺如病毒，并如前文参考文献17所述鉴定所检出的病毒基因群。以RTqPCR定量循环（Cq）值的半定量结果，衡量诺如病毒阳性样本中的病毒载量。粪便样本采集自有症状与无症状的工作人员及居住者；若暴发疑似经食物传播，则额外采集食品从业人员的粪便样本。
