In terms of tracking all the chains, because of the dearth of testing in the beginning, I would suspect any shorter chains of transmission that didn't end in a super-spreader could easily be missed.

It is hard to get tested even now. It was essentially a catch-22. You could only become tested if you had contact with a proven case. But there were almost no proven cases, because you can only become a proven case if you had contact with a proven case.

I don't know what the glass infiltrate is, but morgues overflowing could be a symptom of the government shutdown. For example, in Ecuador, there are bodies just lying on the street because the shutdown and general alarm about the virus means there are less people removing the deceased. The deceased are themselves not necessarily dead from covid-19 (although the news article headlines are worded ambiguously in that regard...).

In general, I see a lot of confusion and lack of clarity, along with cherry picking stats and stories to support a catastrophe narrative.
