Either illness onset date (for symptomatic) or test collection date (for asymptomatic) is used. This differs from Reported Date.A sum of this field will not equal the amount of reported cases, because it only includes cases with complete information.The 7-day average is an average of the 7 days leading up to the event date (including the event date). The purpose of this statistic is to balance out the fluctuation from day to day of reported cases.
