The Know NOW! App from CentrAlert sources its data from a variety of public and private entities. Due to the fluid nature of the COVID-19 pandemic, sources may be added or removed over time. The Know NOW! App is always seeking to find new and reliable data sources to keep pace with this public health emergency but as of June 17th, 2020, the App is utilizing the following:

• The COVID-19 US Data Map uses the Data API from The COVID Tracking Project at The Atlantic, available under a Creative Commons CC BY-NC-4.0 license.
• The COVID-19 Test Sites Map uses data from each individual state’s COVID-19 resources (COVID-19 websites, governor websites, state Departments of Health, etc), with GoodRx.com and CastlightHealth.com used for further information and verification.
