The News' COVID-19 dashboard is based on data from the
Yale COVID-19 Statistics webpage,
which reflects data for both Yale's asymptomatic testing program as well as tests given to
symptomatic individuals. Yale's data is generally delayed by two to three days, and the News
updates our dashboard each time Yale publicly releases its latest counts. Yale has
de-duplicated these numbers so that students who test positive multiple times are only
counted the first time, and so that total tests given reflects the
number of unique individuals tested on a single day.
