De-emphasizing COVID case counts would be a mistake

We seem to be at a bit of a turning point in the COVID-19 pandemic in Canada, maybe not so much because we are nearly out of it (cases remain low, if climbing very slowly, but a fourth wave is expected to ensue as the summer wanes and the Delta variant begins to outperform the vaccines). Rather, it is expected that Canada, and possibly much of the rest of the world, will move away from daily case counts and concentrate more on hospitalizations and deaths.

I must confess this worries me a bit. Yes, I understand that the virus and our ability to control it has changed. Daily cases in many countries are already approaching the height of the second wave, even outstripping it in some, but the death rate is probably a tenth of what it was during the second wave. This, at least, is a good thing. 

But to begin to ignore case counts is to risk losing track of the fact that case counts are, or should be, still important, partly because a higher number of cases means that the virus is still circulating, meaning that we cannot let our guards down and pretend that life has returmed to normal, and partly because the more cases that occur the greater the likeihood of new (and potentially even worse) variants arising.

But also, we should be ensuring that no-one catches the virus, let alone becomes hospitalized by it, because even mild cases can lead to debilitating illnesses. Not only is there the risk (admittedly low, but nonetheless very real) of "long COVID", whose symptoms can persist for months, but also long-term lung, heart and brain damage are increasingly being identified as distinct possibilities. And now, it is becoming clear that there is a cognitive cost to even mild cases of COVID

If we start to get blasé about keeping track of cases, we risk losing track of these implications too. And that would be a shame. Simply put, daily cases are just a really easy method of tracking how we are doing in eliminating the virus. Not foolproof, by any means, but a good rough-and-ready metric.

Certainly, abdicating all responsibility for the virus, even as new cases spike, as Alberta is planning to do (and as several US states have done already) cannot be a sensible move at this juncture, as most medical people, both within and without Alberta, are warning. This thing is far from over; pretending it is finished will not make it happen, as this  Globe and Mail cartoon says quite eloquently.
