Ontario’s Pandemic: The Beginning of the End or the End of the Beginning?

 

The last few weeks have seen a major improvement in Ontario’s daily COVID-19 case account.  The fourth wave seems to have peaked at just under 1,000 daily cases several weeks ago and for the last seven days has averaged under 500 daily cases (See Figure).  This is at the bottom of the scenarios that were envisaged just a short while ago as the fourth wave picked up steam and this may indeed be the beginning of the end of the pandemic in Ontario. At the same time, we may simply be embarking on a new post-pandemic era characterized by intermittent ebbs and flows of infection and a long-term change in how things are done.  In the end, it has been a remarkable learning process.

 


 

We appear to owe this new diminished phase of the pandemic partly to continued public restrictions with respect to the wearing of masks in public places and the high rates of vaccination.   The prolonged restrictions and phased in reopening over the summer has also been wise given the experience of Alberta and Saskatchewan with the Delta variant.  The high rates of vaccination in the province have been having their desired effects and the onset of the vaccine passport system has encouraged more hold backs to go and get vaccinated.  Yet, there are bumps.  The fact that the new QR code vaccine passport many can download for the first time today requires iOS 15 - for many of us a new iPhone - means a lot of us are not going to be conveniently loading it into our Apple Wallets.

 

And while the provincial government is apparently planning to announce a further relaxation next week in pandemic restrictions dealing with capacities in assorted public venues at the same time, it is announcing new restrictions reflecting slower progress in other areas.  The easing of pandemic measures will include ending capacity limits in all locations where proof-of-vaccination requirements are in place, such as restaurants, bars and gyms, a senior official in Ford's government said on Wednesday.  To its credit, it is going to retain the requirement for masking in public spaces.  Moreover, future outbreaks will apparently be met with more local response as opposed to province wide one size fits all provincial lock downs though my guess is that is more aspirational given the heavy handed tendency towards centralization of policy at Queen’s Park.

 

At the same time, it has been recently announced that long-term care homes will be instituting testing for staff and visitors whether doubly vaccinated or not at the same time that it is mandating vaccines for all long-term care home staff by November 15th.  While this continued testing has been out forth as “random” testing to provide early detection of breakthrough cases, some evidence to date suggests that Ontario LTC homes will be interpreting it as weekly testing suggesting that things will not be going back to normal for some time. Calling it "random" may be government political word massage to make visitors to LTC homes think it is not going to be formalized but it remains that the Oxford Dictionary defines random as: "done, chosen, etc. without somebody deciding in advance what is going to happen, or without any regular pattern" and not something done on a weekly basis.

 

The fact that testing is going to be used on doubly vaccinated individuals (who granted can still transmit the virus) while some hospitals have announced that visitors (to be clear not patients) will require double vaccination to get in to see their loved ones suggests that the real elephant in the room is still the high proportion of not vaccinated people in Ontario – for which a lot of other vaccinated people will continue to pay the price.  It remains that as of today only 73 percent of all people in Ontario are fully vaccinated.  And in long-term care homes, as of the latest figures for end of August, more than half of homes had less than 90 percent of their staff doubly vaccinated.

 

So, practice and implementation continue to lag science and evidence though the other revealing result of this pandemic has been how much public health, epidemiology and infectious disease science is a lot more like economic science than they would care to admit.  When it comes to scientific expertise, the pandemic has revealed that we are all economists now. Economists have been the butt of jokes for years about how their economic forecasts always seemed off the mark and yet during the pandemic, epidemiologists, bio-statisticians, and other assorted medical experts, have joined the ranks of economists and weather forecasters – not just in the range of forecasts provided but by the constantly shifting advice.   One does not have to think that far back to recall debates and discussion over whether to close border or wait, aerosol transmission or not aerosol, masks are effective or not effective, take AstraZeneca, don’t take AstraZeneca, etc.

 

In the end, this will hopefully be a humbling experience for science that will improve it.  Economic science, like the other sciences is evidence based and empirical with theoretical frameworks driving the analysis.  Facts are indeed facts but interpretation of the facts via theory and explanation is open to debate, consensus only evolves over time, and most importantly:  decision and policy making based on the evidence and the conclusions drawn from the evidence in the end is not done by the scientists but by politicians and civil servants who have agendas and constraints of their own not least of which is public reception and compliance.  The decisions in the end have been much more coloured by the art of the possible than many would have liked. We are indeed at an end but the drama continues.
