Counts of COVID-19 reported in WALLIS AND FUTUNA: 2020-2021

Project Tycho datasets contain case counts for reported disease conditions for countries around the world. The Project Tycho data curation team extracts these case counts from various reputable sources, typically from national or international health authorities, such as the US Centers for Disease Control or the World Health Organization. These original data sources include both open- and restricted-access sources. For restricted-access sources, the Project Tycho team has obtained permission for redistribution from data contributors. All datasets contain case count data that are identical to counts published in the original source and no counts have been modified in any way by the Project Tycho team, except for aggregation of individual case count data into daily counts when that was the best data available for a disease and location. The Project Tycho team has pre-processed datasets by adding new variables, such as standard disease and location identifiers, that improve data interpretability. We also formatted the data into a standard data format. All geographic locations at the country and admin1 level have been represented at the same geographic level as in the data source, provided an ISO code or codes could be identified, unless the data source specifies that the location is listed at an inaccurate geographical level. For more information about decisions made by the curation team, recommended data processing steps, and the data sources used, please see the README that is included in the dataset download ZIP file.

第谷计划（Project Tycho）数据集收录了全球各国上报的各类疾病病例数统计数据。第谷计划数据编目团队从各类权威数据源提取上述病例数统计数据，这类数据源通常来自国家或国际卫生机构，例如美国疾病控制与预防中心（US Centers for Disease Control）以及世界卫生组织（World Health Organization）。上述原始数据源涵盖开放获取与受限获取两类渠道。针对受限获取数据源，第谷计划团队已获得数据提供方的二次分发许可。所有数据集收录的病例数统计数据均与原始数据源发布的统计结果完全一致，第谷计划团队未对任何统计数值进行修改，仅在针对某一疾病与地区的最优可用数据为单日汇总数据时，将单条病例数统计数据聚合为日度统计值。第谷计划团队已通过新增变量对数据集进行预处理，例如添加标准化疾病与地区标识符，以提升数据的可解释性。同时，团队将数据统一格式化为标准数据格式。所有国家层级与行政一级（admin1）层级的地理位置，均按照原始数据源中的地理层级进行呈现，前提是可识别出对应的ISO代码；但若原始数据源明确标注该地理位置的地理层级存在偏差，则除外。若需了解编目团队的决策依据、推荐的数据处理流程以及所使用的数据源详情，请查阅数据集下载ZIP压缩包中附带的README文件。
