The death toll is dropping largely because the most vulnerable older people have been isolated. Right now, the typical resident at an assisted living, nursing, or memory center facility is locked in their room 24 hours a day with virtually no human contact other than the minimum necessary to keep them alive. .
That is certainly one of the contributing factors for lower death rates. There were reports from several hospitals that since about a month ago, the severity of illness due to COVID-19 infection has significantly reduced and recovery times have also reduced. That is how all virus behave, they are not "constant".
An anecdotal evidence:
In the middle of April, three of my sister's friends, retired doctors in their early 70 died of corona virus in Baltimore County. They were in decent health for their age. That is how potent Corona was then. Now, its a totally different story.
