Don’t care for too much rape, but this is truth.
A mask has no effect on viral transmission, the main transmission path is long-residence-time aerosol particles (< 2.5 μm), which are too fine to be blocked, and the minimum-infective dose is smaller than one aerosol particle...the media is cancer.

Not everyone is a fan of rap. Maybe even less of a fan of white rap. But Tom MacDonald is a very talented, completely independent artist. All of his videos are done by him and his wife. I thought this video encompasses today's situation to perfection.

Even a little rape is too much tho.
Rap, however... normally not a fan but it's refreshing to watch something like this. I would watch this guy rap the news.

Do you mind posting an article or any other reference for the bullshit that you’re posting?
A legitimate source would be much appreciated. Thanks.

@mildlyamusing..are you really this smooth brained?
A mask has no effect on viral transmission lol...back in May of 2020 the CDC released the results of 14 individual studies conducted by various universities and medical institutions on the effectiveness of the mask in preventing the spread or preventing contracting the influenza virus, which is 220 nm's on average. The results were all the same. Neither did the mask slow down or prevent the spread of the virus nor did it prevent or slow down the infection rate of the virus. So if the masks do nothing for the influenza virus, why would you think it is effective against a much smaller one?
CDC Volume 26, Number 5—May 2020 Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures
““In our systematic review, we identified 10 RCTs that reported estimates of the effectiveness of face masks in reducing laboratory-confirmed influenza virus infections in the community from literature published during 1946–July 27, 2018. In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks (RR 0.78, 95% CI 0.51–1.20; I2 = 30%, p = 0.25)”
If you really want me to break it down for you, I will, but if you think a mask works..the jokes on you..
The reason workers in a virus lab wear moon suits, go through multiple sets of sealed doors with decontamination procedures before that suit is removed and breathe pressurized outside air while inside the lab is that these are facts and said virus -- any virus -- will go right through any "mask."
Don’t contaminate the gene pool with your seed

Viruses that cause COVID are not ones that cause influenza, nor are they much smaller.
If you actually knew your science instead of reading your material off of politically motivated websites, you would know that efficacy of surgical face masks against aerosols was found to be superior for a coronavirus than for a virus that causes influenza.
This is not an issue of liberal vs conservative. This is an issue of science.
We still don't really know the effect of face masks against COVID for a population because RCTs with the correct statistical power haven't been done; however, there are mechanical studies and observational studies that show surgical masks are effective, although the effect size has uncertainty.
I'd recommend N95s versus cloth masks or surgical masks for the Delta variant. You just have to test it to make sure it doesn't leak and that it's sealed before use.

Latest study on masks and COVID that just came out shows masks reduced exhaled aerosols containing virus by a factor of 2, although confidence interval is large, so effect size remains uncertain.

The Covid viron is 1/10 of one Micron, you are factually wrong on literary everything. Covid viron is SMALLER THSN INFLUENZA. Look it up. The surgical mask was designed to prevent bacterial infections on patients during surgery while the Doctor's and Nurses communicated back and forth over the open wound. The same reason your DENTIST wears one, to stop splatter from your mouth going into HIS..it has NOTHING TO DO WITH VIRAL TRANSMISSION LOL. It was made to stop 1000 nm's or larger molecules. TCOVID virus is on average 120 nm's, 10 times smaller, and water molecules are on average 282 nm's in size. Where as oxygen on average is .02 nm's in size, and most gasses are close to that. Very tiny. That is why in the military the protective mask is called just that and not a gas mask. If it were a gas mask then you would not be able to breath through the mask. If you still think the surgical mask/N95 or a piece of cloth works then by all means try this. One room holds COVID and one room holds VX Nerve agent. Both very close in size. In both rooms they hold the same small amount. Would you go in both rooms with just a surgical mask or cloth mask? Or would you pass on them both? Or pass on the Nerve agent?
N: This is a Respirator Rating Letter Class. It stands for “Non-Oil” meaning that if no oil-based particulates are present, then you can use the mask in the work environment. Other masks ratings are R (resistant to oil for 8 hours) and P (oil proof).
95: Masks ending in a 95, have a 95 percent efficiency. Masks ending in a 99 have a 99 percent efficiency. Masks ending in 100 are 99.97 percent efficient and that is the same as a HEPA quality filter.
.3 microns: The masks filter out contaminants like dusts, mists and fumes. The minimum size of .3 microns of particulates and large droplets won’t pass through the barrier, according to the Centers for Disease Control and Prevention (CDC.)
Material: The filtration material on the mask is an electrostatic non-woven polypropylene fiber.
Valve: Some disposable N95 masks come with an optional exhalation valve. “The presence of an exhalation valve reduces exhalation resistance, which makes it easier to breathe (exhale,)” according to the CDC.
.3 microns
THE COVID VIRON IS 1/10 of ONE MICRON
Thank you once again for displaying your stupidity

Masks do not work. If you are about to link observational studies go ahead, they are a low form of scientific evidence. Let me show you much better science supporting the fact that they DO NOT WORK.
FACT: There are multiple random clinical trials that have been performed on the efficacy of face coverings of various sorts, from N95 masks on down to cloth coverings in the general population with the aim of identifying effective means of controlling the spread of ILI ("influenza like illness"), specifically respiratory viruses.
FACT: There is NO record established by said Random Clinical Trials (RCTs) in over one hundred years, including those performed in the last 20 years, that establishes statistically-significant effectiveness of face coverings for the prevention of transmission of ILI. Exactly zero science supports such a claim.
FACT: As a direct result of the lack of such evidence the FDA has never issued an approval for any facial covering intended to be used in the general population for the suppression of any illness, including but not limited to Covid-19. In fact I suspect no such approval has ever been sought, otherwise someone would have tried to make money on a "flu mask", making such a medical claim, in previous years.
FACT: It is therefore UNLAWFUL under United States Law for any seller to advertise, market, sell, vend or represent that any facial covering in fact does or will prevent, treat or cure any transmissible disease whatsoever as exactly zero said devices when used by the general population have ever been certified and approved for said use. THIS IS FEDERAL LAW (TITLE 21) AND IS NOT A SUGGESTION.
This is why every package of N95 masks at the Home Deport (and elsewhere) has the clear statement on the "use document" that comes with it which states it does not prevent the transmission of any disease. any disease.
Such a government entity is in fact mandating a direct violation of United States Federal Law and committing said violation itself through promotion of said use.
END OF DISCUSSION.

You NEVER read your fukin links..
Your link..
“Two fine aerosol samples, collected days 2-3 post illness onset, while participants wore masks, were culture-positive.
Conclusion SARS-CoV-2 is evolving toward more efficient airborne transmission and loose-fitting masks provide significant but only modest source control. Therefore, until vaccination rates are very high, continued layered controls and tight-fitting masks and respirators will be necessary.”

"N95 masks are designed to remove more than 95% of all particles that are at least 0.3 microns (µm) in diameter. In fact, measurements of the particle filtration efficiency of N95 masks show that they are capable of filtering ≈99.8% of particles with a diameter of ≈0.1 μm (Rengasamy et al., 2017).
SARS-CoV-2 is an enveloped virus ≈0.1 μm in diameter, so N95 masks are capable of filtering most free virions, but they do more than that. How so?
Viruses are often transmitted through respiratory droplets produced by coughing and sneezing. Respiratory droplets are usually divided into two size bins, large droplets (>5 μm in diameter) that fall rapidly to the ground and are thus transmitted only over short distances, and small droplets (≤5 μm in diameter). Small droplets can evaporate into 'droplet nuclei', remain suspended in air for significant periods of time and could be inhaled. Some viruses, such as measles, can be transmitted by droplet nuclei (Tellier et al., 2019). Larger droplets are also known to transmit viruses, usually by settling onto surfaces that are touched and transported by hands onto mucosal membranes such as the eyes, nose and mouth (CDC, 2020). The characteristic diameter of large droplets produced by sneezing is ~100 μm (Han et al., 2013), while the diameter of droplet nuclei produced by coughing is on the order of ~1 μm (Yang et al., 2007).
At present, it is unclear whether surfaces or air are the dominant mode of SARS-CoV-2 transmission, but N95 masks should provide some protection against both (Jefferson et al., 2009; Leung et al., 2020)."

You really have no grasp of of reality do you..? I’ll tell you what..Let's look at physics and mathematics
We'll start with a single cough or sneeze.
Everyone "knows" that if you cover a cough or sneeze, and you should do it into your sleeve instead of your hand, this will reduce the risk of someone else getting a virus you may have, right?
Wrong.
It doesn't. So says the science! This is a myth, just like it is a myth that you can wear a mask and reduce transmission.
Wait -- you say! YUCK; that's obvious that it helps.
Well, no.
Here's why.
You sneeze and a huge loogie comes out your nose. Yuck! Nasty! Mucus, full of germs.
It goes, if uncovered...... downward, on the floor.
And harms nobody.
It's disgusting, but that's it. You should still do it anyway because it's disgusting not to, but you won't stop a virus by doing so.
What? If I stop the loogie then how come that doesn't do anything?
Because in addition to the loogie out come a bunch of large drops, each also laden with virus. Maybe a few hundred drops. Yuck! Thus covering or physically blocking those will reduce transmission to other people, right?
Wrong again, statistically speaking.
Why?
Because in that same forceful exhale are an enormous number of sub-micron water droplets that are formed as the saturated vapor in your lungs (100% RH in expired air) cools slightly as it travels up from the lungs to the trachea and out the mouth or nose and comes into contact with the ambient air (well, unless it's over 98.6F in the air where you are anyway!)
Remember your basic physics: As any saturated vapor cools it condenses. Any saturated vapor that cools by even a tiny amount will condense -- that is, coalesce the individual vapor molecules into larger aggregates.
Ordinary "tidal volume" (that is, the amount of air you move in a resting condition with each inhalation) is about 500ml. For a cough or sneeze it is much larger; the maximum volume of air that can be inspired in adult human lungs typically is in the range of 4-6L, or eight to 12 times the "at rest" breathing amount.
When we breathe normally we produce very few or no large droplets. When we sing, play a wind instrument, yell, scream, cough or sneeze we produce a fairly large number of them.
We've all "seen our breath" outside when it's cold.
That's aggregation and condensation to a great enough degree that the aggregates are visible; there are thousands to millions more said aggregates that are too small to see and when it's not cold outside none of them aggregate and condense sufficiently to be visible but they are all still there.
Note that during ordinary breathing the mean particle size is sub-micron. Statistically none of these are filtered in either direction.
This is why physics says that masks don't work against viruses and exactly zero RCTs show that they do.
Never mind the repeated attempts to do so including in 1918, which did nothing to prevent the spread.
Every single person that has ever "seen their breath" in the winter months knows, if they think about it for 30 seconds, why masks can't work and don't.
They can't work because blocking 1,000 pretty-large droplets sounds like it's great except hundreds of thousands or even millions of condensed water vapor molecule clusters were also expelled, they have enough virons on them to infect another person and very nearly zero of those are caught by the mask in either direction. The ones you see when you breathe out in the winter are >50um in size (the limit of visibility to the unaided eye); more than 50 times the size of the mean particle you actually exhale. Worse, every one of those tiny particles, unless condensed out or breathed in by someone else can remain in the air for hours since they are small enough to remain within the purview of brownian motion of air molecules; that is, they "float" so to speak because the energy of said molecular vibration and ordinary air currents, even indoors, is large compared to the pull of gravity toward the ground and thus they remain suspended in the air.
The reason we have a flu season, as I've noted, is that the higher the absolute humidity, which tracks with temperature, the greater the odds that further agglomeration of these clusters of molecules will occur and once they get large enough gravity takes over as they are too heavy and they fall to the ground harmlessly.
So your mask stopped the nasty-looking and smelling loogie which can infect exactly one person, unless you wipe it around on people, and 1,000 of the 5,000 modest-size droplets you expelled. This is why the mask gets nasty all over the inside (which, by the way, if left on for any length of time or reused will breaking ed bacteria on the inside surface which you can inhale, and it will be very bad for you if you do so.)
But it's worthless in terms of protecting anyone else because at the same time you expelled the 5,001 droplets and stopped 1,001, which sounds like a decent hazard reduction, you also expelled anywhere from thousands to several million micrometer-size drops, an effective none of which were stopped, all of which are infectious, and thus you actually caught materially less than 1% of the potential infections that can screw someone else!
1% is not statistically significant. Filtering out 0.1-1% of the infectious events out at the source DOES NOTHING.

Linked is a review of RCT that supports the use of face masks.
We can play this game all day. The truth is the evidence is mixed. We need better RCTs to evaluate the effect of masks on COVID in different contexts.

Okay buddy from google..
“The structure of the influenza virus (see Figure 1) is somewhat variable, but the virion particles are usually spherical or ovoid in shape and 80 to 120 nanometers in diameter. Sometimes filamentous forms of the virus occur as well, and are more common among some influenza strains than others.”
https://micro.magnet.fsu.edu/cells/viruses/influenzavirus.html
“Jun 11, 2020 — “COVID 19 virus particle size is 125 nanometers (0.125 microns); the range is 0.06 microns to .14 microns,” the post said
So I will ask again..So if the masks do nothing for the influenza virus, why would you think it is effective against COVID?
A single COVID molecule is 120/125 nm's average and a single water molecule is .282 nm's average. The assumption is that everything a person breaths out is at least four water molecules and one COVID molecule in size. In fact the virus only needs one water molecule to travel on. So how many of them are passed through the mask? Try this and let me know what happens. And don't lie, I already know the results. Put on a mask, lift the mask and with a vape take a normal inhale and replace the mask, now exhale and tell us what happens. I'll remind you that people that vape are inhaling water vapors, whether they are flavored or not, and upon exhaling there is still a good amount of vapor let through the mask. Now imagine standing in line behind some one with COVID, and lets say it is an average of 5 min, now imagine vaping in that spot for five min, this is what it would be like if someone had COVID. Now you are stepping up into an infected area and breathing it in...
I keep thinking you can’t get any dumber and you keep proving me wrong.

The EVIDENCE IS CLEAR 2020 showed us that. Masks NEVER slowed down rate of infection nor SAVED lives..for a BS virus I might add.
We can go by state or country..here in my hometown, Santa Clara County has had a mask mandate for 9 months and over 5 months ago, implemented fines of up to $500 for individuals & $5000 for non-compliant businesses
So what happened? Deaths went up 5200% after they started the fines
If masks save lives, why do they not save lives?
Literally days after Alabama’s Governor publicly said “masks work” in defense of her statewide mask mandate, Mississippi started doing better than Alabama, despite not having a statewide mandate
Alabama’s had a worse hospitalization rate for nearly 2 months since
Every time..they make no fukin difference.

It's been shown time and time again through mechanistic studies (such as the one attached, if you were to read it) that N95-type, surgical, and some cloth masks do decrease the amount of aerosols that pass from one side to the other. Is this always enough to prevent infection? Probably not. Is this sometimes enough? Probably. The question most certainly depends on the viral concentration in the air. If there is too much virus, the masks won't work. But it has been estimated (see linked Science article) that the concentration of virus has generally been low enough for masks to work.
The question remains for each type of mask, are they protective enough in a population to reduce the growth rate of the virus that causes COVID? This question remains unanswered in most contexts.

The question is not unanswered..the question has been the same from the beginning.. if the masks do nothing for the influenza virus, why would you think it is effective against a much smaller one?
CDC Volume 26, Number 5—May 2020 Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures
““In our systematic review, we identified 10 RCTs that reported estimates of the effectiveness of face masks in reducing laboratory-confirmed influenza virus infections in the community from literature published during 1946–July 27, 2018. In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks (RR 0.78, 95% CI 0.51–1.20; I2 = 30%, p = 0.25)”

Seems like one of us actually has other responsibilities besides constant blogging on a website meant for pleasure seekers, but let's see how smooth-brained you truly are:
Question: Imagine yourself locked into a 10 foot by 10 foot room with two people who have been diagnosed as having Covid-19 and who can't stop coughing. Both don't have masks on.
Do you:
A. Put on a mask.
B. Forgo putting on a mask.
What is your answer: A or B?
I'll address the rest of what you wrote later this evening when I have more time.

Rider you are the embodiment of StockHolm Syndrome..again..a mask has no effect on viral transmission..2020 proved this, physics prove this, government laws & regulations prove this. But you can’t think for yourself, I literally typed it all out for you,& you still cannot grasp it, there is zero help for you.
You don’t even realize how a mask works. Masks are worthless when it comes to viral transmission and in addition they are obviously also worthless against transmission that occurs due to contact with contaminated surfaces or objects. That's the physics of it and nobody has ever demonstrated an ability to modify the laws of physics.
Grow up, deal with the fact that masks are worthless, learn to live with the fact that this virus will not be responsive to voodoo or magical incantations by governors, mayors or anyone else.
If this nation cannot face the realities of physics then we are back to the persecution of Galileo and the burning of "witches" at Salem. There is utterly no point in my, or any other thinking person's continued engagement on any matter of economics, politics, public health or other policy if that is to be the regression of intelligence and logic among the people of this nation as what was America is doomed to collapse back into the Dark Ages.

Wear one, don't wear one. I couldn't care less. The decision you make will have little to no effect on me. Being so naive as to think we're coming out of this because of a mask. Or a "vaccine". We won't see life as we knew until we all recover from covid or die from it.
Protect yourself however the fuck you see fit.

@DavisM1
So your answer is B, that you wouldn't wear a mask.
I needed an answer from you to gauge who I'm dealing with. You're clearly not a complete idiot, because you can string words together in coherent sentences, but your logic is simply faulty and you appear to be smart enough to know it.
You write:
"But it's worthless in terms of protecting anyone else because at the same time you expelled the 5,001 droplets and stopped 1,001, which sounds like a decent hazard reduction, you also expelled anywhere from thousands to several million micrometer-size drops, an effective none of which were stopped, all of which are infectious, and thus you actually caught materially less than 1% of the potential infections that can screw someone else!"
Yeah, what you write sound reasonable, but what you're missing is that masks prevent the aerosolized particles from your breath, your cough, or your sneeze from becoming airborne to such a degree and quantity to actually infect others with the virus so long as you're not staring face to face (or preferably, mask to mask) with people who may be infected.
That's the reason why you should wear a mask AND stand 6 feet apart, especially indoors.
As you should know, what really matters is the viral load of what is being inhaled from an infected person. That is why nurses and doctors often get very sick (and die) from Covid-19 because the environment in which they work is often filled with aerosolized particles when emergency wards are filled with sick people. If the medical worker has a tear in their protective gear, or their masks slip off while they are administering care, or if they have to continually reuse protective gear/masks because of supply issues. that's when you start seeing medical workers getting sick.
Nevertheless, cloth mask wearing is the best prophylactic measure we have without depleting the N95 masks needed for medical use. I'm sure you've heard of the analogy where people wearing pants cannot piss on you because the pants prevent the projectile urine from reaching you. Similarly, cloth masks don't necessarily prevent the actual virus from leaving their body but from transmitting the aerosolized particles far enough, and in sufficient quantities, to infect people.
The difference between everyone wearing a mask and no one wearing a mask is obviously significant in terms of efficiency of transmission of the virus.
You referenced a study from the CDC website from researchers from Hong Kong. I'd rather use information from UCSF, consistently ranked the top medical school in the country along side Harvard Medical School, which stated the following:
"Our review of the literature offers evidence in favor of widespread mask use to reduce community transmission: non- medical masks use materials that obstruct droplets of the necessary size; people are most infectious in the initial period post-infection, where it is common to have few or no symptoms (10–16); non-medical masks have been effective in reducing transmission of influenza; non-medical masks have been shown to be effective in small trials at blocking transmission of coronavirus; and places and time periods where mask usage is required or widespread have shown substantially lower community transmission."
The CDC itself does not follow what that one study from Hong Kong that you quoted claims.
And only a grossly irresponsible person would not wear a mask knowing that others around him may be infected.

I've also mentioned this before. You will have doctors, often famous doctors, who say absolutely crazy shit. I've used Scott Atlas, a neuroradiologist from Stanford, as an example. He was Trump's coronavirus advisor who claimed that the United States could achieve herd immunity by infecting as many people as possible and he discouraged mask wearing to serve that end.
I have a family member who is a doctor who has worked with Scott Atlas for years. He told me that Scott Atlas can't even set foot in Stanford now. He committed career suicide by his insane recommendations that has contributed to tens of thousands of deaths.
I also went to one of the best graduate schools in the country where essentially every student was in the top 1% of all college graduates. There is always one or two students in every class that consistently went against the grain and ended up doing crazy shit that ruined their career and future.
When it comes to life and death situations, it is best to go with the consensus of the medical community. Don't follow the outlier who is trying to make a name for himself/herself.
Follow what the vast majority of the top doctors tell you to do, and that is to wear a fucking mask.

@DavisM1
The physics of droplets that you laid out is an example of bloviating. You print a lot of words, for some unknown reason, that are irrelevant to the issue at hand because you miss out on the most important critical detail:
"[Masks] can't work because blocking 1,000 pretty-large droplets sounds like it's great except hundreds of thousands or even millions of condensed water vapor molecule clusters were also expelled, they have enough virions on them to infect another person and very nearly zero of those are caught by the mask in either direction."
Pure bloviation, but nice try.
You're right that a person emits over a thirty minute period about 3 million particles. Masks can't possibly prevent the release of so many particles. If every respiratory particle were to contain a virus, we'd be fucked.
But we have calculated from measurements the amount of viruses distributed in such a large number of particles. We usually find that just a minor fraction of exhaled respiratory particles contain viruses. In fact, the number of viruses in 30-minute samples of exhaled air are typically low with mean values of ~53 for coronaviruses, ~38 for influenza, and ~96 for rhinoviruses. (See link for measurements and calculations).
From medical centers, we have found that the range of inhaled viruses is ~1 to ~600 in 30 minutes. (See link).
Now, the number of viruses needed to cause infection is uncertain, but let's say it is 100 over the period of ~50 minutes, which is a very low value needed for infection. Therefore, the probability of infection is dependent on the ratio of inhaled viruses over 30 minutes to 100. It turns out that where the range of inhaled viruses is ~1 to ~600 in 30 minutes, the probability of infection is usually less than one, even without wearing a mask (see link). It's been shown that surgical masks and KN95 reduce the outward particle emission rates by 90% and 74% on average during speaking and coughing, respectively, and thus lower the probabilities of infection.
Thus, it is feasible, at least theoretically, that masks should lower growth rates of infection in a population. The problem is that it has been very difficult to measure such an effect, hence the uncertainty that they have a significant effect in the real world. That's been the issue, not the mechanics of it.

It's true when the number of inhaled viruses is at the high end of the range given (~600 in 30 minutes), like in some hospital rooms or laboratories, then the probability of infection is 1, and masks will do no good.

The problem of RCTs not working for masks is not a problem that specific to masks, but rather is a problem of taking an intervention that works mechanistically (like masks) or biologically on an individual level (like certain medicines) and measuring the effect this intervention has on stopping the spread of a contagious disease.
For example, PrEP is a medicine that is 99% effective at pre-exposure prophylaxis of HIV. The problem is when scientists try to measure the effect of PrEP on HIV spread in a community, they find it hard to measure consistently. There are a lot of hypotheses as to why. For example, perhaps the people most involved in the spread fail to use it properly. Nonetheless, problems in measuring effects on spread persist.

Both of you are False & do not understand what a mask is used for. I’ll attempt to explain again. All those surgical masks you see..yea those were meant to protect the environment from the person, ie: the person being operated on. They were designed to protect droplets of blood from entering the doctors mouth as you lay on the operating table, much like the dentist is being protected from saliva entering his mouth as he commences work on yours. NOT the other way around. It’s too protect the human environment from the person wearing it. In a sterile environment, it's not uncommon to see doctors and nurses switching to a new mask every 30 minutes during a procedure. You also always see nurses put on a new mask while making rounds. And that's in sterile environments. Your grocery store is NOT sterile. Imagine how quickly those masks get clogged in non-sterile environments. Pretty..fast meaning by the time you've walked from your car to the building door your mask is probably bullsh*t in it's effectiveness to protect others (cause remember it's not designed to protect you in the first place, only the environment from you).
There were over 14 studies in the CDC post I linked (yes not all pertaining to masks) but we can go through the ones that did.
You both clearly did not try my experiment..Put on a mask, lift the mask and with a vape take a normal inhale and replace the mask, now exhale and tell us what happens. Now what comes out is only what we can observe, and once again..you also expelled anywhere from thousands to several million micrometer-size drops, an effective none of which were stopped, all of which are infectious, and thus you actually caught materially less than 1% of the potential infections that can screw someone else!
Again, if what you both claim is true..we would have seen evidence for it last year..yet the exact opposite is true. Everywhere masks were mandated, cases/deaths increased, never once did they prevent anything.
Health “experts” say flu cases have virtually disappeared globally because people are wearing masks and practicing social distancing, but Covid-19 infection rates are exploding because people are not wearing masks and social-distancing. Don’t question the narrative. It’s ScIEnCe.
Aerosol transmission of influenza A virus: a review of new studies
Raymond Tellier. J R Soc Interface. 2009.
“This distinction of ‘short-range aerosol transmission’ is not merely academic; aerosolized particles would readily penetrate or circumvent ordinary surgical masks, and penetration of aerosolized influenza viruses into the LRT where they can initiate infection would account well for the association of aerosol transmission and severe disease.”
