Hi Baron, in your post, there are a few fatal flaws.
1. You are assuming that as soon as viral particles being expelled from human respiratory tract, its final form remain the same. But the reality is alot more complex. Depending on the humidity, smaller droplets after expulsion, can split, its water content can evaporate quickly, and becoming air born. However, if there is a mask barrier initially, it can be stopped. Not all droplets are made of same size and shape, and falls in the same way. We live in a world of chaos.
2.Some models of the transport and viability of airborne viruses have assumed that the carrier liquid can be modelled as water This is an oversimplification that ignores the complex composition of respiratory fluid. For example, a 60 µm droplet has a volume of approximately 0.1 nl and would contain approximately 1 virion if the virus concentration in the bulk liquid were 107 ml−1, if the bulk concentration also applied to the droplet. Assuming a simplified model of respiratory fluid composition, the droplet would contain approximately 1 ng of salt, approximately 1 ng of total protein and approximately 0.06 ng of surfactant. The mass of each component is at least five orders of magnitude larger than the mass of the virion. These components form the virion's microenvironment and should not be disregarded.
3. While the physical properties of respiratory droplets in ambient air have dominated discussion of airborne transmission, the chemical properties of the droplets have often been neglected. The chemical microenvironment immediately surrounding virions in droplets and aerosols is likely to be an important determinant of their stability.
4. After a droplet falls onto the ground or.a surface. Depending on the immediate environment, the virions and its surrounding respiratory fluids can potentially take a long time to evaporate and break down as well. The next person then come across droplet, would be able to transfer onto their hands, and into to their respiratory tract. And thereby spreading the infection. Remember, COVID 19 can be transmitted by BOTH aerosol AND droplet.
The fatal flaw in your post is persisting with droplet transmission when it has been accepted that Aerosol is the greatest form of transmission.
Droplets cannot be inhaled therfore masks offer no protection with droplets. You need a respirator for Aerosol protection which means anything less is useless then you have the issue of contracting Covid through the membranes in your eyes which i linked a post to.
This whole mask mandate thing came about because of Political Science combined with Pseudoscience to fool the gullible.
Quote:PETER HITCHENS: Face masks turn us into voiceless submissives - and it’s not science forcing us to wear them, it’s politics
19 July 2020Britain’s muzzle consumption is now so high that six months from now there will be reports of dolphins and whales floundering about in an ocean made sticky by millions of gallons of hand-sanitiser, as they choke on congealed clumps of used muzzles.
On July 12, Deborah Cohen, the medical correspondent of BBC2’s Newsnight, revealed an astonishing thing. The World Health Organisation (WHO) had reversed its advice on face masks, from ‘don’t wear them’ to ‘do wear them’.
But the key fact was that it had not done so because of scientific information – the evidence had not backed the wearing of face coverings – but because of political lobbying.
She revealed on Twitter that: ‘We had been told by various sources [that the] WHO committee reviewing the evidence had not backed masks but they recommended them due to political lobbying.
’ She said the BBC had then put this to the WHO, which did not deny it.In March, the WHO had said: ‘There is currently no evidence that wearing a mask (whether medical or other types) by healthy persons in the wider community setting, including universal community masking, can protect them from infection with respiratory viruses, including Covid-19.’
The American TV news channel CNN reported on March 31 that Mike Ryan, executive director of the WHO health emergencies programme, had said at a briefing in Geneva: ‘There is no specific evidence to suggest that the wearing of masks by the mass population has any potential benefit.
‘In fact, there’s some evidence to suggest the opposite in the misuse of wearing a mask properly or fitting it properly.’
Earlier that same month, England’s chief medical officer, Chris Whitty, had said that wearing face masks would do little to combat the outbreak.
At about the same time, Dr Jenny Harries, a Deputy Chief Medical Officer, warned that people could be putting themselves more at risk from contracting Covid by wearing muzzles. She said masks could ‘actually trap the virus’, and cause the person wearing it to breathe it in
On April 3, the other Deputy Chief Medical Officer, Professor Jonathan Van-Tam, said he did not believe healthy people wearing them would reduce the spread of the disease in the UK
The truth is that the muzzle policy is all about power and fear.
