How is it that the droplet transmission dogmatists aren't demanding RCTs for handwashing? For any disease. If the thesis that #COVIDisAirborne needs proving by RCT, then what is good for the goose is good for the gander.
While we are at it, can we also demand RCTs of mosquito nets/repellant, and water sanitation systems to prevent waterborne illnesses including cholera and typhoid?
Since we're being RCT purists, don't we also repeat RCTs for COVID vaccines/boosters and antivirals for each new variant that arises? We can't just rely on bench science and observational data to extrapolate safety and efficacy, can we?
Medicine can't sink to the level of physics and be reduced to mechanistic science! What has laboratory determination of mechanistics got to do with science, anyway? Only suck-it-and-see trial-and-error random empiricism can be called scientific!

A 🧵on @3M Aura N95/FFP2/FFP3 respirator models. The Aura is the standard go-to high-filtration respirator of the pandemic. It's kept countless healthcare workers safe. It's hard to go wrong with it. If in doubt when choosing a respirator, ditch the earloops and go for an Aura Image
When asked which was her favourite 3M model, forced to pick among her children, safety division vice-president even Dr Nikki McCoullagh chose the 3M Aura model
The key to the Aura's success is high particle filtration efficacy on more critical tests of PFE like the NIOSH saline test and EU paraffin oil test, combined with a fit test pass rate across diverse subjects of around 93% multimedia.3m.com/mws/media/2045…

1. A bit of a heads up for US followers. SoftSeal have a secret (shhh….) 20% off sale on their N95 respirators. Use the code SECRET20 at checkout. Their Flat Fold N95 comes in children’s sizes too softsealmask.com Image
2. The SoftSeal 3D N95 with the silicone seal is currently the preferred respirator used by @sri_srikrishna (you’ve hopefully seen his excellent website patientknowhow.com). It seems to have an unusually high fit test pass rate
3. I have some SoftSeal 3D N95s on order but haven’t received them yet. I was intrigued by the claim that 63% of those who failed a fit test on a regular N95 (presumably 3M Aura/VFlex N95s?) go onto pass on the SoftSeal softsealmask.com/testimonial-ke…

A little reminder to always buy N95 respirators with head straps. Avoid ones with earloops (unless you've passed a fit test in it— there is an approximately 50% failure rate). There's no such thing as an N95 with earloops masksexplained.com/index.php/many…
In the EU, unfortunately, you can find FFP2 respirators with CE markings, but even these should be avoided as per the warning put out by HSE in the UK
The AU/NZ equivalent of an N95/FFP2 respirator is the “P2” respirator. You can also find earloop P2 respirators like the AMD model. I also failed almost instantly in this though not as quickly as in a KN95/KF94. There is a ~50% chance that you will too.

At the heart of COVID minimisation lies a Social Darwinist assault on medicine. It emanates from the implicit neo-Darwinian lying at the core of neoliberalism, which assumes all societal progress is driven by unfettered market competition.🧵
Government intervention in the natural competitive order undermines market competition, destroying society by propping up uncompetitive entities that ought to be permitted to be liquidated by natural attrition.
We cannot repeat the mistakes of the Soviet block and its unnatural state interference in capitalist competitive marketplaces. A state lead moonshot approach to solving the COVID crisis will see the West suffer a downfall like the Soviet Union @MazzucatoM amazon.com.au/Mission-Econom…

Easy. The libertarian no-war-against-COVID “pacifist” types are laissez-faire WRT COVID as a civilian health problem but if seen as a military assault with a bioweapon, are tempted to use it as a paranoid ruse for total war against economic rival, China. 🧵
The reason the CDC was once a well-funded whip-crack organisation was that it was on the front line of war preparedness in case of all-out biological and nuclear war against the Soviet Union
After the collapse of the Soviet block, the CDC became less of a biomilitary organisation and more of a civilian public health organisation serving the good of the populace. Hence, seen as a costly nuisance that needed to be silenced by its political masters

🧵Heraclitus thought that the universe was in flux like fire. Nothing ever “is”, for everything is always coming into being. Playing with viruses is playing with fire. It is not what a virus “is” but its potential for what can “become” that we must fear
One day, we may look back and realise that by asserting that SARS-CoV-2 “is” a fomite-born disease and not blocking the airborne transmission evolutionary pathway, we accelerated its evolution towards exploiting this loophole ever more efficiently
In future, we should pre-emptively block the ability of novel viral threats to spread efficiently via the airborne route of spread and clip the potential of the virus to evolve flight
