We can end the pandemic wearing N95 masks (respirators).

Yet another study using real-world data demonstrating that universal masking reduces transmission by *at least* 9-fold.

This would extinguish the pandemic.

😷 #MasksWork

journals.aps.org/pre/abstract/1… Dr Richard Sear uses a conservative estimate of N95 filtering efficiency (90%). Real-world ‘exhaled breath’ data shows even better performance with non-fit-tested N95s: ~98%

which would then reduce transmission by a factor of 40

stopping the pandemic in its tracks.

AIR FILTERING:

“The problem seems to be one of translating success in the laboratory to success in real-life settings”

Why? Poorly implemented interventions deliver poor results. Like wearing a mask poorly.

Answer … give up? No, do it better.

✅“trend towards the treatment groups to have fewer infections. This finding was more consistent for observational studies, especially HEPA cohorts” ✅🆗

“Is this how it’s always going to be?”

Good question. The virus mutates to get better at infecting us. There’s absolutely no sign that this is slowing.

Lab studies show that the virus’s ability to infect (enter our cells) can potentially grow by a factor of ~600.

This constant, continuing risk of severe illness will be with us for years.

This is like allowing TB to circulate freely … and doing nothing.

“Never-ending waves of severe #COVID19 disease”

How do we get out of this mess? Physical measures (masks, ventilation, HEPA filters …)

PLUS: ‘#NasalSpray’ strategies:
1️⃣ disable virus
2️⃣ disable host entry point (nasal ACE2 receptors)
3️⃣ boost nasal antibodies (secretary IgA) 1️⃣ Melbourne trial of nasal Heparin spray to disable virus spikes (necessary for access yo host cells):
