Does anyone still believe Natural Herd Immunity has been the right solution since da pandemic began?

    Yes, surgeons wear masks to reduce the chance of droplets falling onto a patient's incision. Masks are often rated to bacteria size but viruses are much smaller. On a cold day, if you breathe hard enough, you will see your huff in the cold air. These fine water droplets could contain Covid. You will never ever find a manufacturer's datasheet on a mask stopping viruses. In labs, the technicians are suited up to an outside air supply.

    You believe the average mask worn by the general public is the equivalent to a surgical mask :roll:

    If I mistook your post I apologize!

    True for flimsy paper masks or cloth masks but not true for advanced masks with good facial seal like N95s and N100s, which can and do decrease the amount of virus-laden aerosol that the wearer breathes in, as evidenced for example by a study done by the Department of Physics of Duke University, and a large meta-analysis (of some 27 studies) published on Lancet done exclusively with coronaviruses (SARS-1, MERS, and SARS-CoV-2) showing an 82% reduction in relative risk for the mask wearer. While I don't have these links on me right now, I've posted them (actually several times) in my posting history.

    What most people don't know is that a virus the size of the coronavirus (about 0.1micron) is subject to Brownian Motion (look it up) and electrostatic charges, and is indeed trapped by masks even if the mask pores are larger than 0.1micron. As a matter of fact, filtration of particles of 0.1 micron is better than what happens for particles of 0.3 micron because the latter are not subject to Brownian Motion. So, masks are rated based on tests done with particulates of 0.3 micron which are called MPP or "maximum penetrating particle." So, NIOSH N95 masks are rated at 95% for particulates of 0.3micron but actually they perform even better for 0.1micron, at about 98%. Viral load matters, so if you decrease inhalation of virus-laden aerosol by 98%, you do decrease the relative risk of catching the illness; not to forget that there are N100 masks too (although these are harder to find), and these filter out 99.97% of particles of 0.3micron, presumably even better for 0.1micron.

    So, no, the common idea that circulates out there and here, that viruses are too small to be filtered out by masks when their are in aerosol form, is blatantly false. People think it's just like a mosquito going through a link fence, but it isn't, due like I said to Brownian Motion and electrostatic charges. The SARS-CoV-2 does get trapped by advanced masks.

    Now, a different problem is that most people don't wear those advanced masks and even if they do, they don't know how to achieve a proper seal.

    The problem then resides with distribution, access, and education regarding how to do it right.

    Obviously a person with a flimsy mask dangling below the person's nose has zero protection... while a person with a well-sealed N95 mask that covers mouth and nose at all times, is significantly protected.

    Currently N95 masks are no longer in short supply and the price has dropped to about $2 a piece for a NIOSH-Certified, Made in the USA N95 mask. They are available from several vendors including Amazon. They come with instructions. People should be able to get them, learn how to use them, and be better protected. Still, a tiny minority does so, therefore overall for our population, masks haven't been terribly protective but that's not the fault of the masks themselves.

    KN95 masks, the Chinese standard, should not be worn given that 60% of them are counterfeit. They are knock-offs that lack the inner layer of blown melt that is actually the filtrating layer. So more than one in each two KN95 masks are useless, so I wouldn't want to go through that risk. I threw away all my KN95 masks and for several months I've been only wearing N95 masks everty day and N100 for certain situations such as air travel.

    I didn't even bother clicking on this. The opinion of ONE surgeon wouldn't sway me either way. Surgeons are not known for being the most scientifically-driven doctors anyway. We like to tease them that they are glorified butchers, haha; not necessarily well-versed in things like how to run and interpret a randomized controlled trial.

    I trust much more the experiments done at the Department of Physics of Duke University and the large meta-analysis of more than 20 studies on masks done exclusively with coronaviruses that I mentioned above, than the opinion of ONE surgeon.

    Do you know what you call the person who graduates last from the worst medical school in the nation? Doctor...

    Anecdotal opinion of one individual doctor is not scientific evidence. In the hierarchy of evidence, the top spot is occupied by large meta-analyses of RCTs, and the bottom part is occupied by "expert" opinion (with many other categories of studies in-between). Even when the person issuing an opinion is indeed an expert (and I doubt that a surgeon possesses advanced expertise on the physics of a mask and the virology and epidemiology aspects of mask use), this kind of opinion is still considered, scientifically speaking, as the lowest possible level of evidence.

    He also claims to be the former editor of a medical journal. In any event, what he says makes perfect sense and jives with the empirical data. What you say does not. I wonder who I should believe.

    I think many countries are starting to see the light and going the Swedish route.

    So..... Norway said screw this crap.

    Norway drops all Covid-19 restrictions

    Rowdy celebrations erupt in Norway as COVID restrictions end


    Dear Australia... take notes.

    The vaccines DO NOT bring on herd immunity. That has been proven now repeatedly. We really missed the boat by not going much harder on therapeutics. We went all in on the vaccines and ignored the therapeutics and in many cases fought against them.

    Wrong. Norway have removed restrictions because practically 100% of adults are vaccinated

    And Sweden did go into lockdown due to their disastrous earlier no lockdown route ending up with thousands of deaths

    They are not 100% vaccinated. Your username should be changed. You're peddling lies. They are only 8% ahead of the U.S.A. and 5% ahead of Australia. They are are at 76%, while we are at 68% and Australia is at 70%.

    Norway, Great Britain, Denmark, Sweden.... they are all moving forward and removing restrictions.

    76% of the whole population including babies and children, NOT 76% of adults. Try getting something right

    And just to show you how wrong you are:

    Really? Did Norway tell you that? Or is this what you tell yourself to make the universe conform to your preconceived notions?
