“I haven’t seen a Covid patient in the E.R. in weeks and go to work now expecting not to,” Spencer told me, “despite a swirl of Covid in the community.”
Among other things, a decoupling of cases and severe illness would mean that hospitals were less likely to become overwhelmed during future Covid surges. When hospitals avoid getting swamped, they can provide care to every patient who needs it — which becomes another factor that reduces bad health outcomes.
‘Misleading’
Going forward, this newsletter will begin to pay less attention to statistics on coronavirus cases and more attention to statistics on hospitalizations. “Looking at the data in the same way we’ve been accustomed over the past two years can be misleading,” Spencer said.
We won’t completely ignore the case numbers, because they still have some relevance. But the cases data has become both less reliable and less meaningful than earlier in the pandemic.
It is less reliable because of the recent closure of many testing clinics and the shift toward at-home testing. The data on Covid hospitalizations and deaths doesn’t suffer from these problems and appears to be as accurate as it was earlier in the pandemic.
The cases data is less meaningful than it used to be because vaccines are universally available to U.S. adults — and vaccines tend to turn Covid into an illness of similar severity to a flu, including for the elderly and the immunocompromised. More recent treatments like Paxlovid play a role, too.
One telling comparison: In the county that includes Seattle (which keeps detailed data), the daily Covid death rate for boosted elderly people has recently hovered around two per million. That’s higher than the national flu death rate during a mild influenza season and somewhat lower than the rate during a heavy influenza season.
