No, the study you posted omitted the data that did not align with its narrative & did no follow up on the passengers lol


COVID-19 is an airborne infection acquired by inhalation of virus-containing droplets and aerosols into the nose or mouth,
or via the eyes and drainage into the nasal passages through the lacrimal duct.

Any virus will bypass even the best facemasks through the nasolacrimal duct (also called the tear duct).

Your tears clean your eyes from dust, pollen, and viruses, which are then drained into your nose.

Any droplet of infected fluid that lands on your facemask are turned into tiny aerosol particles as you inhale, and gets deep into your lungs, increasing the chances of getting infected. In other words, masks make things worse.

As you exhale the same thing happens and the chances of infecting others increas

Anti mask logic: masks block CO2 molecules, but not respiratory viruses.

Just lol

I think you need to re-read lol..large droplets are blocked, but a virus spreads through aerosol transmission & only low infectious dose is needed.

-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.”


…masks don’t work for airborne pathogens. That’s why we wear respirators that filter airborne pathogens.

I'm starting to think you do this as comic relief.

Thanks for the lulz. Fare thee well

It's super extra sciency when you have to read the text that explains the graph that summarizes the text. They teach this in graduate school.

Masks work extremely well…

They're like lawn signs - you see someone wear one, and you can tell their political views ( or lack of ) with a high degree of certainty.

But graduate school is little more than advanced communist brainwashing

Looks like we can safely conclude the more shots and boosters you get, the more likely you are to be hospitalized or to die from COVID.

The more masks you wear the more likely you are to get sick.

So what do "experts" recommend? More shots, boosters, and masks. Just following the science.

I'll need to see the graph on that before commenting.

That's the narrative

Props for a well-timed trust me, bro that's unrelated to the topic. We made it to page 2

Oh..okay


Possible toxicity of chronic carbon dioxide exposure associated with face mask use, particularly in pregnant women, children and adolescents – A scoping review

.1. Effects of masks on carbon dioxide re-breathing
In the study of Ulrike Butz’s dissertation [64] (an internally peer reviewed thesis research study) focusing on possible rebreathing of carbon dioxide in 15 healthy adult male volunteers, a carbon dioxide partial pressure of up to 21–24 mmHg was found under a surgical mask after 30 min [64]. This corresponds to about 2.8–3.2% carbon dioxide of the inhaled air under the mask.
In Pifarr ́es mask-experiments of 8 adult females and males, a health-critical value of carbon dioxide concentration (CO2 vol%) was measured in the air under the masks after few minutes. The concentrations of 14 162 ppm with a mask versus 464 ppm without a mask were statistically significant with p < 0.001 increased by a high factor compared to the initial value (******t air) and even more following exercise [65]. According to these experiments, masks can be responsible for a greatly increased CO2 concentration of the inhaled air, which roughly corresponds to 1.41–1.7% carbon dioxide in inhaled air under the face mask (p < 0.001) [65].
A project at the University of Delft used a validated method that clearly demonstrated that carbon dioxide re-breathing under standardised laboratory conditions (test suite) after 1 min is at least 0.9% CO2 for N95/FFP2 masks [66]. Those elevated carbon di- oxide levels of inhaled air, particularly under N95 masks, were also found in physiologically relevant short-time modeling studies. This confirms a constant increase leading to an averaged 1% inhaled CO2 per breath during simulations of eight breathing cycles in 33.65 s (see video in mentioned publication with animation of CO2 distribution with and without a respirator)[67]. Another modeling study shows that wearing N95 masks results in carbon dioxide accumulation, the volume fraction of CO2 reaches 1.2% after 7 breathing cycles and is then maintained at 3.04% on average. The wearers re-inhale excessive CO2 with every breath taken from the mask cavity [68].
In 2013 Sinkule already evaluated 30 different N95 respirators using the NIOSH Automated Breathing and Metabolic Simulator (ABMS) through 5 min work rates and found elevated CO2 levels in the inhaled air ranging between 1.28% and 3.52% [69]. These results are consistent with measurements of CO2 in the dead space of the masks from experimental studies in humans with values of 2.8 [70] and 3.2% [71].
In a self-experiment in 2020 Geiss measured the air under masks under laboratory conditions and only found an accumulation of carbon dioxide between 0.22 and 0.29% within 5 min mainly under surgical masks [72].
In a prospective observational study in 2021, Rhee examined the carbon dioxide concentration of 11 healthy volunteers during regular breathing and sitting at rest while they put on different types of masks for 15 min. Serial CO2 measurements were performed with a nasal cannula at a frequency of 1 Hz [73]. The measured 2.4–2.6% CO2 concentration translates into a highly significant in- crease in CO2 with a KN95 respirator and a valved respirator at the nasolabial fold (p < 0.0001), which is much greater than the NIOSH 8h threshold limit value [57]. The National Institute for Occupational Safety and Health (NIOSH) has an 8h threshold limit value – time-weighted average recommended exposure limit (TLV-REL) of 0.5% – and a 15 min threshold limit value – short-term exposure limit (TLV-STEL) of 3% for CO2 – in workplace ******t air [57]. Rhee’s quality study (serial CO2 measurements with a high per- formance CO2 sensor at a frequency of 1 Hz for 15 min) demonstrates a significant increase in end-tidal CO2 concentrations among healthy volunteers while donning KN95 respirators.

That's more like it!

Keep bringing the lulz

It’s funny that people are compromising their immune system from masks to you?

No. But, your posting style is hilarious
