Respiratory Syncytial Virus Laboratory Data (NREVSS)

Approximately 600 public health and clinical laboratories located throughout the United States, participate in surveillance for respiratory syncytial virus (RSV) through CDC's National Respiratory and Enteric Virus Surveillance System (NREVSS). The dataset contains a weekly summary of the total RSV tests and RSV detections reported to NREVSS. These data are reported on a voluntary basis. Clinical laboratories do not report demographic data through NREVSS. Testing practices and the number of participating laboratories may change from year to year. Results can be changed two years after the initial reporting week. However, discrepancies may be noted and updated at the discretion of the data stewards and key stakeholders. Data are collected from collaborating university and community hospital laboratories, select states and county public health laboratories, and commercial laboratories. This information is submitted and updated on a weekly basis. While NREVSS strives to present the most precise national, regional and state respiratory viral trends with the least amount of burden possible for participating laboratories, there are a number of inherent limitations to this surveillance system. NREVSS does not collect patient-data or demographic information. Multiple samples may be collected from a single patient, so NREVSS results do not necessarily reflect the number of patients tested nor does it reflect hospitalizations or deaths related to a particular virus. Participating laboratories vary in size, testing capabilities, and areas served. Some institutions may receive and test samples from sites across a given state or even from multiple states. Without direct knowledge of the population base, NREVSS cannot be used to determine the prevalence or incidence of infection.

美国各地约有600家公共卫生和临床实验室通过美国疾病控制与预防中心（Centers for Disease Control and Prevention，CDC）的国家呼吸道和肠道病毒监测系统（National Respiratory and Enteric Virus Surveillance System，NREVSS）参与呼吸道合胞病毒（respiratory syncytial virus，RSV）的监测。该数据集包含向NREVSS报告的RSV检测总数和RSV阳性检出数的每周汇总。这些数据为自愿上报。临床实验室不通过NREVSS上报人口统计学数据。检测实践及参与实验室数量可能逐年变化。结果可在初始报告周后两年内修改。然而，数据管理员及关键利益相关方可根据实际情况记录并更新差异。数据收集自合作的大学及社区医院实验室、选定的州和县公共卫生实验室，以及商业实验室。这些信息每周提交并更新。尽管NREVSS力求在为参与实验室减轻负担的前提下，呈现最精准的全国、区域及州层面呼吸道病毒流行趋势，但该监测系统仍存在若干固有局限性。NREVSS不收集患者数据或人口统计学信息。单个患者可能被采集多个样本，因此NREVSS结果未必反映接受检测的患者数量，也不反映与特定病毒相关的住院或死亡情况。参与实验室在规模、检测能力及服务区域方面存在差异。部分机构可能接收并检测来自某一州内多个地点甚至跨州的样本。由于缺乏对人群基数的直接了解，NREVSS无法用于确定感染的患病率或发病率。如需了解RSV监测与研究的更多信息，请访问：https://www.cdc.gov/surveillance/nrevss 及 https://www.cdc.gov/rsv/research/us-surveillance.html
