Science has completely confirmed masks reduce the transmission of droplet born virus by as much as 85%.

It is true that the type of masks the general public wear might not stop aerosol based infection, primarily because the general public do not use disposable masks correctly, but that is a different thing altogether to droplet transmission. However, Dr Cath Noakes has noted controlling air turnover in buildings has a significant influence on reducing aerosol transmission. Aerosol transmission is considered to be very unlikely in open or well ventilated spaces.

Interestingly preliminary indications are this Influenza season will be less prevalent primarily due the wider global use of masks in public spaces.

Quote:A properly fitted N95 will block 95% of tiny air particles down to 0.3 μm from reaching the wearer’s face.

Quote:Evaluated 44 masks, respirators, and other materials with similar methods and small aerosols (0.08 and 0.22 µm)
N95 FFR filter — >95% efficiency
Medical masks — 55% efficiency
General (cloth) masks — 38% efficiency
Handkerchiefs — 2% (one layer) to 13% (four layers) efficiency.

This might finally get you to quieten down.

You've posted a link and only picked out the bits and pieces you like from the introduction, while the whole article goes on to explain why your general anti-mask argument is completely and unequivocally wrong! Most N95 rated masks (not respirators) even disposable ones filter down to sub-micron level, but they are only effective if you change them regularly which is the problem the public has. People wear the same disposable mask day in day out and once they are damp and contaminated from the moisture in exhalations they aren't as effective.N95 masks are the best, but not necessarily N95 respirators because they might have pressure relief valves that open during exhalation. General medical masks are almost as effective as an open window. The commercial cloth masks and other types are partially effective for droplets, the homemade single layer types of bandana or gaiter are almost useless.

That scatter gun approach you employ has shot your own argument in the foot, ................ again! ;D

Sweden is great example of what happens when you stop listening to the loopy conspiracists and start respect the science.

I can't imagine how you pick out examples that so badly support your argument, surely you aren't so unlucky that this happens by chance?

You focus on the N95 masks and the like.
