Fig. 1. Data flow overview. SARS-CoV-2 viral samples and contextual data are collected by Public Health, hospitals and labs. Some samples are selected for sequencing based on national and regional priorities. After sequencing, regional Public Health authorities select samples that will be shared publicly. Sequence and contextual data from these samples are uploaded to the data portal using the DataHarmonizer and FASTA uploader. From the portal, the public can view or download contextual and sequence data from across the country. Data can also be accessed for value-added resources, such as Duotang, ViralAI, COVID-MVP, and CoVizu, via the API. Green check marks on the figure indicate points in the data flow where human quality assurance/quality control (QA/QC) and/or ethical oversight take place.
