Oswin et al: The Dynamics of SARS-CoV-2 Infectivity with Changes in Aerosol Microenvironment; no doubt, simulations so we must be careful in terms of how much simulations reflect real world

by Paul Alexander

Coronavirus loses 90% of its ability to infect us within 20 minutes of becoming airborne – with most of the loss occurring within the first five minutes, the world’s first simulations of how the virus

This paper is very interesting. https://www.medrxiv.org/content/10.1101/2022.01.08.22268944v1

Key statement: “A decrease in infectivity to ∼10 % of the starting value was observable for SARS-CoV-2 over 20 minutes, with a large proportion of the loss occurring within the first 5 minutes after aerosolisation. The initial rate of infectivity loss was found to correlate with physical transformation of the equilibrating droplet; salts within the droplets crystallise at RHs below 50% leading to a near instant loss of infectivity in 50–60% of the virus. However, at 90% RH the droplet remains homogenous and aqueous, and the viral stability is sustained for the first 2 minutes, beyond which it decays to only 10% remaining infectious after 10 minutes.”

Again, be careful as this is a simulation. But adds another dimension. The key for me is this, I and a team of researchers looked at all of the mask studies and evidence and can say definitively that the blue surgical masks and white masks are ineffective and actually very harmful. Do not work.
