True BUT- the virus doesn't travel on it's own. It is on droplets of many sizes and many can't get though those holes.It isn't great protection but it does give some.
Here's the problem with that. When you cough or sneeze or even just breathe, that air isn't stopped by a loose fitting, cloth mask. It can easily just leak out around the mask. Ever notice how glasses fog up when wearing a mask? It's because all that air is exiting the mask. These masks are purely for show.
You know, I come into threads like these and I never know who to reply to. So I look for someone who seems level headed and gets it.
I'm an APIC infection control nurse. Kind of interesting how a year ago there was all this literature coming out saying masks aren't very effective, and how now, mandatory mask orders are praised by the exact same people.
The truth is an exposure and an infection are different things. A guy I pass at the grocery store and sneezes and I breath in a little of it, I might be exposed, I PROBABLY won't get infected. If my lovely charming wife gets sick with something like the flu or covid-19 or pneumonia or the common cold, I'm swimming in that stuff and I'm likely to catch it if my immune system can't kick it's ass before.
The problem with masks is that most people that get infected, with anything, it's not because they stood too close to you at the grocery store, it's because you spent a long time around them and the surfaces they infected. Masks don't do anything for that, and studies show you are more likely to touch your face adjusting your mask then if you just didn't wear one.
Masks to offer some protection, just not really any reliable realistic protection.

So far so good.
and the surfaces they infected.
This isn't likely the case for respiratory viruses. The person coughing up a storm behind you - yes, that's a likely source of infection. Touching the same shopping cart they did? A possible source or respiratory infection, but not as likely as the coughing is.
Masks don't do anything for that,
They certainly do. Maybe you've forgotten your basic chain of infection. Maybe you've forgotten about viral load. Cloth or surgical masks won't stop all of the droplets coming out. They might filter 40-60% out. Testing by laboratories show that a high velocity air stream, such as a cough, reduces the filtration even further than that. 10 minutes in the presence of someone filtering out even 30% of their droplets is better than 10 minutes in the presence of the same person with zero percent filtration.
and studies show you are more likely to touch your face adjusting your mask then if you just didn't wear one.
This is why I dislike theoreticians. Instead of reading a study watch a few hundred people wearing masks for hours at a time. In practical application, people do touch their masks a lot. People do touch their faces without wearing masks. The people wearing masks aren't usually touching inside their masks. (some still do) They aren't touching the parts of their faces such as the nostril and mouth where the virus can easily enter the body.
Transmission via the contact route has not been proven for covid-19. Transmission via contact is not the primary way this virus or other respiratory viruses are contracted.
Masks to offer some protection, just not really any reliable realistic protection.
Incorrect. They offer varying degrees of protection depending on how they are worn. A lengthy period of time in a surgical mask next to a coughing covid patient will still get you sick. Briefly walking through the same space that a coughing covid positive patient did a few minutes before, and that same surgical mask will give a you a fair degree of not catching the virus.
If the virus were as easily transmissible via physical contact as you and many others surmise, then we'd have far more health care workers infected. Hundreds of thousands of provider+patient interaction experiences over the last 3+ months contradict the claims you are making. The ones in our hospital system that got sick were those who interacted with a patient without a mask. The ones who had physical contact with a covid+ patient and were wearing masks weren't the ones getting sick.
I do remember all kinds of advice from the infection control 'experts' early on (late January through February). The advice changed many times, sometimes on the same day. These 'experts' were wrong then and still wrong, because they can't apply basic laws of physics to pathophysiology. If most of them were practicing clinicians, they'd be dead by now from their own mistakes.
Maybe minimal protection. However, that doesn't mean it will prevent spread among large populations. There's just no evidence of that. Mask wearing is very common in Asia, and the virus still spread like wildfire there.
Also, I believe the small benefit of minimal protection a cloth mask may provide is negated by the fact that 99% of people don't use them properly. They touch their face and mask many times a minute. Infection can easily be spread that way. Some people don't have them over their nose, some people pull them up and down constantly, some people don't store or wash them properly. The are all reason the WHO still recommends against masks for everyone.
Covering your cough/sneeze with a tissue or arm is going to do the same thing a mask would, without all the inconvenience and constant impediment to breathing.
Ever notice how glasses fog up when wearing a mask? It's because all that air is exiting the mask. These masks are purely for show.
No, your glasses fog up is because the air you exhale is being slowed down and forced out around your face rather than spreading into the outside world in a giant cloud. It reduces the amount of spread by the wearer. It's not meant to protect the person wearing the mask, it's to protect those around the person wearing it.
But i know you don't care, you can't be bothered to be mildly discomforted for 30 mins while grocery shopping. You're basically this https://gph.is/1kK4Xrd
Wrong, the air simply goes around the sides and top of the mask. It'll follow the path of least resistance. You're right; I don't care. I have a right to breathe, so you can shove the mask right up your ass.
The fogging up on glasses is from water that's in vapor form condensing on a cold surface. Vapor isn't droplets. Evaporation separates water molecules from everything else, that's why original water purification methods involved evaporating water & running that gas through a cooler to liquify it again. It's called condensation.
LOL, wrong. Water vaper is a bunch of tiny droplets. What do you think clouds are. Also, when breathing, you can feel the air blowing up to your eyes and around the mask. It's not rocket science. Go shill somewhere else.
It also forces you to touch your face more. So instead of washing off that virus you been molesting all day, you're now smearing it on your face because of the mask.
Most people knew how to use PPE in december. By february we were justifying filthy and unsanitary habits because of these technical truths.

True. It's why I said "some protection". Also my my point was specifically to the hole size and the size of viruses.

Hey asshole, the virus IS airborne. Also, 99.99% of scientists and doctor's don't wear cloth masks.
Go back to Reddit and get fucked, cuck.
It protects others from collecting your spittle.
