COVID-19 Testing Group

The COVID-19 Testing Group is a community resource for sharing the latest information on COVID-19 testing, prevalence, seroprevalence, and burden studies, planning tools, and data. This website is maintained by the Larremore Lab at the University of Colorado Boulder with collaborations in the Grad Lab and the Mina Lab at the Harvard T.H. Chan School of Public Health, and Brennan Klein at Northeastern University.
