The virus is being spread by aerosol, meaning it can hang in the air like smoke. This is what is making people sick. It is far smaller than the holes in the weave of a mask. Aerosols are what make their way down to the lungs. All the hand washing and double mask wearing in the world cannot stop aerosols. Masks can only capture droplets. Droplets are larger than aerosols but are less dangerous because they are often caught in the nose and throat and don't make their way to the lungs. Fomites are droplets that land on surfaces that other people may touch. These are not very dangerous. There are plenty of older covid-19 articles that would have you believe that fomites or droplets are the most dangerous and that aerosols played very little or no part in transmission. I have no idea why this theory was getting pushed when it has been known for decades that this kind of virus is mostly transmitted by aerosol and that masks can do little or nothing to stop them. Believing in masks is just a belief. It's not science. Well you're certainly entitled to your 'opinion' Dr. BigQuackOfEnglandUK, however wrong that opinion may be, as the strongest evidence in favor of masks and hand washing come from studies of real-world scenarios.... files.fast.ai/papers/masks_lit_review.pdf

November 13th, was in a meeting in a room with a co-worker, neither of us wore masks and sat 8 feet apart. Three days later he is in quarantine after a positive test comes back - he revealed he "felt off" the day of our meeting. I had no symptoms ever.
December 8th had dinner at a friend's house, and one of the invited said she wonders if she should go to a doctor because had not been able to smell anything for two days, and food seems to have lost it's taste,too. She later tested positive, and so did two guests. The host and me? Nothing, nada, zilch.
However, had my first shot Tuesday.

"A new study in the journal Blood Advances backs up what researchers have been seeing for a while: People with Type A blood are at a much higher risk for contracting COVID-19 while people with Type O seem to be more protected from it, according to a growing body of research." www.menshealth.com/health/a34394784/blood-type-coronavirus-covid-19/

The movement of those microscopic airborne droplets increases in places using forced air HVAC systems which, unless they have the special filters, just blow them all over. THIS is the major reason airplane travel spreads sicknesses. Those overhead air jets re-circulate from all over the plane.

THIS is the major reason airplane travel spreads sicknesses. Those overhead air jets re-circulate from all over the plane. I just happen to work on commercial HVAC & Refrigeration for a living and thus know the real deal on this subject. You can just forget the corporate BS about any "special filters", most commercial establishments only want to pay for the bare minimum when it comes to maintaining their systems. I can show you pictures of some of the equipment in major chain stores that is FILTHY DIRTY beyond your imagination. , trust me... What I personally took it upon myself to do at the start of the pandemic was to open the fresh air intakes further than normal (if equipped), figuring that getting some fresh air into these buildings will be of a general help.

Makes me think you and your friends were very lucky. Well, call me crazy......call me irresponsible........but I prefer listening to those medical professionals who have devoted years to studying and finding cures for infectious diseases, especially since both my wife and I top the list of those at risk. As of this morning, 25,239,990 Americans have been infected and 421,118 have died, all within a year. How are you in at risk groups if you've been listening to medical professionals, Bruciepops? My wife and I are in our 70's and we both have pre-existing conditions. i.e., we are most likely to be among that 3% who die.

I watched the un-muzzled Dr. Fauci on TV last night and he said what he and other real experts have been saying all along. The sooner a large majority of the population is vaccinated, the sooner we will move into herd immunity, or, "herd mentality", as Trump put it.

I wonder if people having pre-existing conditions - obesity, lifestyle-induced diabetes, etc. or live unhealthy lives - smoking, eating excessively, sedentary - are doing anything besides sitting in line waiting for their Fountain of Youth COVID vaccine shot.
Just thinking out loud.

Scary thing is a number of folks who get the vax think they are immune, and like right away. They want to go back to life before COVID, no mask, etc.
We are at about 25M confirmed cases and the estimate is 5 to 10 times (determined by the wastewater treatment facilities tests) MORE than that have gotten the virus and must have been asymptomatic. So, if there are up to around 200 - 250M cases so far and there are 330M in America, we should be at or close to 'herd' immunity.
I don't know if the US can get 100M vaccines into people in 100 days as Biden plans, but if he can AND with the additional cases from casual community spread increases of the total, then the US should be about done with this by end of summer.

Just thinking out loud. Thank you for thinking out loud. I have no idea how many people have risk factors because of unhealthy life styles. For my part and my wife's, we both exercise and eat healthy, nonetheless, we are both old and have pre-existing medical conditions.

The sooner a large majority of the population is vaccinated, the sooner we will move into herd immunity, or, "herd mentality", as Trump put it.Dr. Fauci feels "liberated" under Biden's administration for the simple fact that he's now going to be held less accountable for the very many times when he talks out of both sides of his mouth. Consider me not a very big fan of the undersized doctor... And fwiw, although you dislike Trump, you should give him the credit and thank's he's due for 'Operation Warp Speed' getting that vaccine produced, distributed, and into your arm in record breaking time. I promise you that with a leftist bureaucracy in charge there's NO WAY that it would have happened, NO WAY www.npr.org/sections/health-shots/2020/09/29/917899357/how-operation-warp-speeds-big-vaccine-contracts-could-stay-secret

Believing in masks is just a belief. It's not science. I think early on this stemmed from the classification of the virus as "not airborne", where "airborne" has a much more restrictive meaning than what the public might take it to have. Anyway my understanding is that you need to be exposed to a virus in a quantity above a certain threshold to be likely to actually get infected, which is why you are very unlikely to catch it in open air for example, and that the weak statistical effect of masks is in reducing this quantity. But I could be wrong as I am not a virologist, merely a caneguru.

I agree with Bruv re the aerosols. But in this case I would rather go with the belief that any clean mask is better than none, NOT for the aerosol factor (Covid 19 virus) but because of the mask's ability to at least catch some droplets that could cause other diseases or impurities that could weaken the body, and cause lowered immunity to aerosol viruses.
The washing of hands and surfaces has long proved to be of value. Surgeons washing their hands up to their elbows pre-surgery should surely convince people to wash their hands at all times where possible, not specifically as a Covid preventative, but one of simple measures to combat any infection that could render the body more vulnerable to Covid.
The wearing of a mask is also socially reassuring that the wearer cares enough about others, whether it's effective or not. Don't need to be fanatical about it. The guy ranting at the lady in a previous post, for example. We all know what he was suffering from and it wasn't Covid fear.
