Let's embrace a new concept: 'Smart Masking'
The Omicron wave is receding, but Covid hasn't vanished and is still a potent risk to a huge portion of the population. Until we get better vaccines/treatments, we should make the common spaces we share as safe as possible.
The new CDC approach of focused protection (which is being mirrored around the world) has been tried multiple times before and failed. It will result in the death or disability of massive numbers of people.
Let's create safe common spaces with the tools we know that work well against Covid: clean air, rapid tests, better masks. Some who deem themselves at low risk will return to pre-pandemic activities, which is fine... but does not mean we abandon those who simply can't do the same
People of all risk categories have no choice but to go to grocery stores, attend schools, or visit hospitals. Unless they're wearing a well-fitting N95, poorly ventilated spaces will be a huge risk to them.
As we better understand the immunological effects of this virus, it is becoming clear that this is not something you want to get repeatedly. Each time carries the risk of Long Covid and immune system over-activation, as I review with @fitterhappierAJ
The end of this wave is a good opportunity to recharge our collective batteries. But Covid has not vanished.
Dismantling our defenses now ignores the certainty that new variants will come at us in future. We need to be smart about keeping our common spaces safe in the meantime.

Why isn’t the pandemic over yet? Why did we require boosters? Authorities including the CDC are finally acknowledging that our vaccines provide protection for only 3-4 months at a time. I interview @fitterhappierAJ to go over possible reasons why.
I’ve been closely following @fitterhappierAJ’s takes on Covid and immunology. Initially I didn’t want to believe his predictions regarding T-cells, but they have stood the test of time and are now being confirmed by multiple lab studies
This is part of a lecture series by @masks4canada, to chart future directions of this pandemic. What can we do to change course, or at least ameliorate ill effects? Many of our political leaders want this to be over now, is this realistic? This is what we hope to address.

Thankfully Covid hasn't touched my family yet. In the absence of any advice from the authorities, these are some tips on how you can minimize your exposure while living a life as close to normal as possible. I'll expand in more detail in this 🧵
The Omicron surge is ending, a huge portion of the population has fresh immunity from boosters or from getting infected. Many have gotten Long Covid via the infection route unfortunately. Hopefully immunity will stand up in the face of the BA.2 variant, but time will tell.
I have two children under 5 who are not eligible for vaccination, and those of us in a similar bind, like the immune compromised and elderly, are being left to fend for ourselves as our governments rush recklessly to remove protections.

What I imagine a chief public health officer would write, but can't:
“Dear citizens, I write to explain some difficult realities. We are tired of fighting Covid-19. Our strategy was entirely based on vaccines, and though they are amazing, their benefits are proving fleeting...
"We could have built a strategy to supplement our vaccines with multiple mitigations, but we did not spend the time or the effort to do so despite having two years to plan and implement this...
"We ignored compelling evidence that the virus was airborne and highly dangerous in poorly ventilated indoor spaces. Instead, to avoid offending powerful personalities within our ranks, we stonewalled and now are completely unprepared to contain this virus...

It is NOT inevitable that our kids will get Covid. The tools exist, including comfortable kid-sized N95 masks, HEPA filters, to prevent this.
Some opine that kids N95 masks are too hard to wear, are harmful, etc.
Let me ask you: do these kids look like they're uncomfortable?
This table from @masknerd shows excellent filtration from well-fitting masks; many are KF94 (N95 equivalent) masks from South Korea, where their use is routine and expected.
It is unfortunate that national media is platforming physicians who push the inevitability narrative. One of the key lessons I learned in medical school: you do not shrink from a problem because it is hard and difficult!

It must be bewildering to sort through the conflicting messaging out there now. Problem is everyone is:
- in a frenzy preparing for an Omicron wave, getting boosters out etc
- in deep shock about the rapidity of spread and what that implies
No one knows what lies next...
So part of the messaging you're seeing is accepting reality that it will be very difficult to avoid getting infected this round. Had we spent the last 2 years preparing to fight an airborne pathogen with ventilation, filtration and N95 masks, maybe most would have had a chance...
But this is likely one of many future rounds with this virus. SARS2 will win this one, and most cases will be mild; boosters will limit the damage, buy us 3-4 months of relative protection for most. The elderly, small children and of course the unvaxxed will be hit hard...

After working several days in a row in the ER, can reasonably say a few things.
Omicron definitely is more mild... for the vaccinated. Unlucky folks on the older end or with comorbidities can get it more severely though.
For the unvaxxed, same deadly virus. No doubt about that.
The symptoms have changed as well.
Before the hallmarks were loss of taste and smell, severe body aches, chest pain and shortness of breath,
Now most (vaccinated) people present with a sore throat, runny nose, mild cough for a few days.
Last night, of around 45 PCR swabs we ordered,every single one was positive for Covid.
If you have cold or flu-like symptoms in Toronto now, you have to assume it is likely Covid regardless of what a rapid test or PCR tells you.
