> as if COVID disappears when you're eating

No, but you can't really eat with a mask on so keeping it on for the entire rest of the time minimizes the risk of spreading and transmitting it. Even if it's not 100% perfect, it still has a significant positive benefit.

can you provide some links to the evidence of this?

[misiti3780]

I disagree.

[naikrovek]

you disagree with how statistics work?

taking off your mask to eat does not negate the rest of the time you wore the mask.

how the hell do people not understand why masks work? I do not understand this.

an analogy:

let's say I am at work, and I fart, but oops, it's poo instead, and now it's all over this side of the conference room floor, even in places you can't see with the naked eye. should I have worn clothes? clothes are so intrusive and restrict my ability to move and express myself, and it's immoral that you create a rule that keeps me caged when I only crap in the conference room three times a year.

the poo in that analogy represents the aerosol saliva and mucus of someone that is contagious with anything, which is stuff that is regularly produced when people talk or breathe. the clothes are a facemask.

how do people not understand why facemasks are effective? I don't want to step in anyone's crap that they left behind wherever they coughed or sneezed or touched the break room chair. wash your damned hands and wear a facemask if you're sick, dammit.

Show me the statistics or studies that show that the mask policy on airplanes in the US as of today (aka hundreds of people in a small, closed environment with no fresh air, where mask are taken off for long periods of time and then put back on again) reduce spread of COVID compared to if there was 100% masking (presumably would reduce the spread) or no masking at all (basically the currently policy)

I understand statistics, you have no statistics to back up your claim. Just so we are clear, I think masks do work if they are used properly - they are not used properly on airplanes in the US, so they are pointless.

It's not a study from the US but it includes enough flights where there were confirmed index cases and there were 4 levels of masking rigidity. The case we're describing, where people only unmask to eat, there were no transmissions.

> On flights N–R with the rigid masking policies (meals served) of Emirates Airlines, no secondary cases were identified on Day 14 screening despite 58 passengers who were PCR+ on a total of 5 flights of 8 hours each with ~1500–2000 passengers.

thanks!

That's fine. Disagreement, in and of itself, isn't a refutation of my point, though.
