"Are you my mummy?" [/obscure Doctor Who reference] Well then you've gotten it doubly-good. Typically when an area ratchets up their testing, their reported cases goes up, as well, since un-diagnosed cases are now diagnosed. So even after you have done more testing, the positive cases are going down to nothing. Bravo to that. One of the reasons many elderly deaths are listed as Covid-19-related in some of the larger American cities is financially motivated. When a patient dies from heart failure or kidney disease or any other pre-existing condition, the hospital may get a certain amount of compensation/payment from Medicare or Medicaid, but if they list the death as a result of Covid-19, they get a bunch of other compensation from all the myriad funding resources set up to combat the disease. So if a patient has the virus but also had severe obesity, diabetes or any other condition, you can be sure the hospital will try their best to declare the patient died as a result of the virus and not any of their underlying conditions.
