When 500 new cases were recorded after the tests, the total number of positive cases increased to 2000 cases + 500 cases = <<2000+500=2500>>2500 cases.
With 50 recoveries, the total number of cases reduced to 2500 cases - 50 cases = <<2500-50=2450>>2450 cases.
On the third day, with 1500 new cases, the total number of cases became 2450 cases + 1500 cases = <<2450+1500=3950>>3950 cases.
If 200 people recovered from the virus, the total number of people with Coronavirus became 3950 cases - 200 cases = 3750 cases
