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. The News' data begins on August 20th while the distribution of cases by students and staff begins on August 26th.
