My friend, I wish to give you my opinion from a healthcare providers point of view.
I really dont care what we used to fight this virus, anything helps. One case turns into 2, then 4,8,16 and so on and so on. Surgical masks protect you from droplet spread and this is how this is spread, droplets.
Let me give you an example, have you ever seen the PPE worn in a hospital? It literally looks see-threw and you wonder how the hell is that going to protect you. Its prevents droplets from penitrating and you can wear and not sweat a storm. This is how masks works, unfortunately many are not worn properly, they dont seal very well and people wear them way beyond their effectiveness.
The reality is everything helps. What makes is virus so deadly is it has a asymptomatic stage which means you can spread it and dont even know. SARS was more deadly but patients became ill right away and you knew as a healthcare provider to quarantine them. So wearing some type of face covering will provide some protection.
I hope this helps. I will provide the difference between an aerosol and a droplet in a moment.
