What is displayed: Daily number of cases. For cases where illness onset date is available, the illness onset date is used.
For asymptomatic cases or cases with no available onset date, the test collection date is used.
A white trend line is also shown: each white dot shows the average of the case numbers over the 5 preceding days.
How it's calculated: Metro Health conducts an interview with each COVID-19 case to determine their illness onset date (i.e. the first day their symptoms developed).
Additionally, Test collection date is available for every case reported to San Antonio Metro Health, and this date is used in instances where a case could not be interviewed or didn't have any symptoms even though infected.
The results for each day are tallied to show daily number of cases.
Goal: A sustained decline in the number of new COVID-19 cases for at least 14 days.
