If they work, why can’t we carry one wearing masks and not lockdown?
Brakes and seatbelts works btw. We don’t stop driving. Your logic makes no sense at all
masks are not working so we need more so called solutions. Hence lockdown.
Some masks better than others

1. They aren’t (like anything else in life) perfect. I can’t believe this has to be explained to people. If you multiply a failure rate x more of the population infected x higher transmissibility factor, you will see more infections that happen despite masks (or any other intervention).
2. a lot of transmission is happening in UNMASKED setting. Private gathering, restaurants, bars, concerts etc. Did you notice that most of the new restrictions were focused on potentially unmasked / close contact situations?
That's because hospitals use N95 masks. Which completely reinforces the point of my thread.
They also throw out their mask, or disinfect it after each shift.
Most regular citizens don't do this
Hospitals don’t always use n95 masks, just for high risk patients and procedures, and early in the pandemic, n95 use was much less than now. If your argument is that n95s are best, I agree with you 100%. If it is that anything else is useless, I disagree, based on the accumulated evidence from the pandemic so far, including numerous observational studies and a few properly controlled ones. Findings are pretty consistent. Masks of all types reduce transmission, and other important outcomes, with fitted n95> unfitted n95/kn95> surgical> cloth. With omicron, and it’s increased transmissibility, this hierarchy is probably more relevant.
I don’t think it’s worth continuing this because you can’t tell the difference between <100% efficacy and 0% efficacy.
Oh I do, I just don’t want to sit around locked at home until the scared people create a zero risk community. It’s never going to happen. As you said, nothing is perfect. So let’s get on with it. No lockdowns.
The studies of the numbers do.
There is no point going around this again. You just want replies. Have a great day.
That’s an entirely different question than do masks work, straw man argument.
Masks reduce transmission, public health measures reduce transmission, and there are costs, especially to the latter. If you want to debate the relative cost / benefit of infection vs public health measures, that is a separate question.
But the covid numbers didn't show any improvement with each wave we had.
If anything it got worse
Still waiting for these studies that show covid virions travel through the air on their own and not in aerosols.
So if ICU capacity fills up and they are now deciding who gets help and who goes home, regardless of COVID or another reason one is in emerg, that is ok with you as long as you can go eat at your favorite restaurant?
There’s no reasoning with someone like yourself stuck in March 2020. I bet you still wear flares. The same old arguments won’t stick.
You are wrong once again but hey, believe what you like, it is your right to be constantly wrong.

Covid is breathed out in a bunch of ways, droplets, aerosols and virions

I applaud the fact you linked a study but I don't see anywhere it says that covid is spread by free virions. Here's what they actually say.
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).
They do say N95 can block particles that size but they have no evidence of covid transmission at that level. It is also quite a dated study (apr. 2020) that talks about viruses in general, not specifically about covid.
So even though you admit the main transmission is through droplets and aerosols, you are still trying to claim that masks that block droplets and aerosols are useless. Hmm.
Most of us look at evidence. The virus has changed since Mar 2020 and we have lots more evidence now. There is a difference between guessing and occasionally turning out to be somewhat correct and following the evidence.
