Never, infections have always been a foucs of tracking because infections lead hospitalizations lead deaths (and hospitalizations have second-order impacts on mortality from other causes when they reach a critical level, even beyond direct COVID deaths.)
If you only focus on deaths, you are weeks behind the curve in reacting.
I guess, death numbers weren't growing as expected.
It's a bit like climate warming temperature predictions.
I appreciate it's hard to do forecasts but the media doesn't help selling actual problems to the public by constantly twisting the narrative.
From a non-medical, "just following the news" perspective, there was a pronounced shift. A few simple google news search will show this.
That’s based on taking the IFR and working backwards from reported deaths at different ages.
Infections happen earlier than hospitalizations and deaths but the count depends on people getting tested.
