ASTHO created a Testing Prioritization Guidance layer using Esri’s ArcGIS online mapping tool. Data was sourced from health agency websites, executive orders and guidance documents. The layer displays information on state/territorial level guidance on testing prioritization from health agency websites. Please note, local authorities may also issue declarations or executive orders that are more restrictive in nature. This information is not included on this layer. Information is assessed regularly by ASTHO staff for relevance to state/territorial health officials’ priorities in their COVID-19 response. Updates to this layer will occur periodically.Data Definitions:Testing Prioritization Guidance - Health agencies that have issued guidance on testing prioritization to meet COVID-19 response needs.Terms of Use:If you plan to use this map to advance your own research or to disseminate the information we’ve presented here, please reference the below data citation, using DataCite’s format for citing.ASTHO.
