WHO document drops on #SARS2 transmission, so I opened this up as if it was a tactical nuke needing defusing.
But holy cow...
WHO Airborne Risk Indoor Assessment (ARIA) Technical Advisory Group with LIDIA MORAWSKA as the CO-CHAIR!?!?
CERN?!?!?
WHO Environment and Engineering Control Expert Advisory Panel (ECAP) with Cathy Noakes on it and ASHRAE liason?
An actual model?
I do see the dreaded Dr. IPAC Droplets on the committee... hmm.

Indoor #airborne#risk#assessment in the context of #SARSCoV2 : description of airborne transmission mechanism and method to develop a new standardized model for risk assessment
I'm only at the Executive Summary, but, holy cow is correct.
"The SARS-CoV-2 virus can spread in several ways: through zoonotic transmission, direct and indirect contact transmission, direct deposition transmission, and inhalation or airborne transmission. An increasing body of evidence [28]–[31] suggests that it is transmitted through infectious fluids released from an infected individual as particles of different sizes and quantities, such as during breathing, speaking, coughing and sneezing. While the largest particles travel downwards quite rapidly, the smaller ones remain suspended in the air for longer periods and can travel farther distances. When people are in close proximity, transmission of infectious particles can occur through direct inhalation (short-range) and deposition onto the mucous linings of the respiratory tract and ocular membranes of a susceptible host particularly in the absence of face covers and ventilation. ‘Long-range’ transmission can occur in enclosed settings when infectious particles accumulate over time in a given volume, where the concentration of virions is sufficient enough to cause infection once infectious particles are inhaled by a susceptible host."
I'll be sitting down to carefully read the rest of this now!
I wish we could see what's happening, who is on the side of public health and how they're teaming up to push against this nightmare, and who specifically is trying to stop them.
I think a big part of our problem is that it's very hard for most people to imagine that ANYONE would actually do things so counterproductive and depraved as what's going on around us right now.
It's like that line in Fear and Loathing, "The only hope now, I felt, was the possibility that we’d gone to such excess, with our gig, that nobody in a position to bring the hammer down on us could possibly believe it."
