Define “Confirmed COVID-19 Cases by Day”
Your Pima County case count totals don’t add up. As of 5/28/2020, the website lists 202,914 PCR tests with 6.6% positive (13,392), and 84,691 Serology tests with 3.0% positive (2,540). This gives a combined test total of approximately 15,932. However, the website lists a total of 17,763 confirmed cases. So, even combining the PCT and Serology tests gives a shortfall of 1,831 cases. How do you account for the missing confirmed cases? Are you combining Serology and PCT test in the "Confirmed COVID-19 Cases by Day" and "Number of Cases" results? Why? Please explain your methodology for determining total confirmed COVID-19 cases.
