The "we are finding more because we are testing like crazy" theory is bogus. You are finding them because they exist.
You won't get rid of it unless you test. The US test rate is only about average, but came too late anyway.
When the patients arrive almost dead to the hospital is too late.
Here is Australia we had no deaths for over a month, and now we have had two and a spike in cases in one state.
From the start though we have not had a mask policy. Well actually we did, the policy was that masks were not necessary, and that has been the case.
Masks do not protect the wearer, they protect other people.
Basically the people who would wear masks voluntarily are those that care about other people and therefore didn't get it in the first place because they took precautions.
The ones that are reckless probably wouldn't wear them anyway, unless to hide their identity.
