CDC NREVSS（国家呼吸道和肠道病毒监测系统）周度RSV检测标本和阳性数据集，是一个来自美国疾病控制与预防中心（CDC）的开放监测数据集。该数据集专注于呼吸道合胞病毒（RSV）的实验室检测数据，通过NREVSS多病原体实验室网络收集，但此Socrata视图仅包含RSV部分（其他病原体如流感、副流感、hMPV、腺病毒等存在于兄弟数据集中）。数据覆盖时间从2010年7月10日到2020年6月27日，更新频率为每周（观察中位数间距为7天），地理覆盖美国次国家级区域（10个唯一位置ID，如HHS N区域）。主要数据列包括：rsvpos（每周RSV阳性标本数，单位：标本/周）和rsvtest（每周RSV检测总标本数，单位：标本/周），均为事件类型数据，聚合方式为求和。附加列包括：testtype（测试类型，分为抗原或PCR，每个日期和区域对应两行数据，分别代表一种测试类型，下游阳性率按测试类型计算）、outlier（异常值标志，1表示源数据标记为异常点，被排除在CDC发布的趋势外）、location_name（位置名称，例如HHS N，用于追溯性，规范位置ID为US-HHS-N）。解释注意事项：PCR和抗原检测计数不可直接比较，PCR在2018年后增加使用，而抗原检测是长期骨干但敏感性较低，因此不应跨测试类型求和数据。数据集通过Socrata开放访问，许可证为其他，层级为2，用于呼吸道监测。

CDC NREVSS — weekly RSV test specimens and positives is an open surveillance dataset from the U.S. Centers for Disease Control and Prevention (CDC). It focuses on laboratory test data for Respiratory Syncytial Virus (RSV), collected through the NREVSS multi-pathogen lab network, but this Socrata view exposes only the RSV portion (other pathogens such as influenza, parainfluenza, hMPV, adenovirus, etc. are in sibling datasets). The data covers the time period from 2010-07-10 to 2020-06-27, with a weekly cadence (observed median spacing of 7 days), and geography at the subnational-region level in the US (10 unique location IDs, e.g., HHS N regions). Key columns include: rsvpos (specimens testing positive for RSV per week, unit: specimens/week) and rsvtest (total specimens tested for RSV per week, unit: specimens/week), both of value type incident and aggregated by sum. Additional columns include: testtype (Antigen or PCR, with always 2 rows per (date, region) — one per test type, and downstream % positive computed per testtype), outlier (1 indicates the source flagged this point as an outlier, excluded from CDCs published trend), and location_name (e.g., HHS N for traceability, with canonical location_id as US-HHS-N). Interpretation caveats: PCR vs antigen counts are NOT comparable; PCR ramped up post-2018, while antigen has been the long-term backbone but is less sensitive, so do not sum across testtype — they are parallel signals. The dataset is openly available via Socrata, with license other, tier 2, and used for respiratory surveillance.
