Testing is miles better now, the real infection rate was perhaps 10 times or more higher than confirmed cases early on, they were only testing hospital admissions at first because of lack of tests.
Deaths might be lower now because care homes and hospitals are protected better, oldies and vulnerable are being cautious, higher % of infections are in the young, viral load is smaller in some of those contracting it because of mask wearing, distancing etc. Those admitted to hospital have a better chance of survival too, dexamethasone and remdisivir is reducing mortality by a 5th up to a third in some patients.
I think we are in a lull now. I think cases and deaths will rise again over winter, to what extent will depend on how well we combat it, and how open the govmt want the economy to be. Doubt we'll see anywhere near the death rate of April, just hope tbe economy can recover quickly.
