By what? Also, many or most rooms are only about 10- 15 feet across. Again, that's a matter of wealth, not physics. Yep. You will see people wearing it in clinical situations.

If people sneeze at 100 miles per hour then, to make sure that the particles go up not across, you need an upward velocity near 100 MPH You need that all across the room- because you can't be sure where someone will be standing. Such rooms exist...

I wonder if this discussion has lost focus on the fact that , for much of the world, "air conditioning" means opening the door.

I would put a lot more effort than I should into making the mat slightly bigger each time...

The HEPA filters used in biohazard labs would fix it. The problem is largely the noise from the fans. Bacteria and viruses are particulate. The ones where they don't allow people are probably pretty near sterile for exactly that reason.

What grade 3? Maybe, by way of balance, the media should not turn up to his election gigs.

And his supporters will call it "authoritative" and "strong".

You can do it, but it's not easy. https://en.wikipedia.org/wiki/Cleanroom The problem is the hurricane you need . A cough can travel as fast as 50 mph and expel almost 3,000 droplets in just one go. Sneezes win though—they can travel up to 100 mph and https://www.lung.org/blog/sneeze-versus-cough

Presumably, his comments on chloroquine, (and mexico paying for the wall etc.) are like his idea that people should try mainlining dettol- just sarcasm.

Why would someone get roasted for asking if we can check if something is true as Macorn is doing?

The experts are right. But the anecdotal evidence is interesting. The cost (in whatever terms) of doing the trial isn't high. The potential benefits are large. So it's worth doing the test. The costs of what Trump is suggesting are much higher. The benefits (if there are any) are similar. That's the difference between the two approaches. One is reasonable, the other reckless.

But Trump thinks he already knows the answer. That's why he's getting roasted (along with his financial interest)

We now need to add "It was the international Maritime Organisation's fault that we hit the iceberg, so I'm not paying my membership fee".

Unless they realised he was unfit for office and kicked him out.

When Romney's the good guy, you know things are bad. Because he'd be in jail.

Well, since you ask; can I take it back and get a refund? It rallis isn't what I was hoping for.

Inside of it, the death toll is already (reportedly) one. The person who died from misunderstanding hydroxychloroquine as chloroquine Outside of the fact that he's wrong, I don't see the fact that he's wrong causing a problem. ... obviously... I'd like him more if he didn't lie about his competence to deliver medical advice. Why does he choose to kill people (who don't dislike him) in this way? That's OK. just as long as the rest of the world calls him the "German president of the USA".

It it turns out to be dangerous snake oil (and it looks like it wil), do you think Trump will take responsibility for the damage he caused?

Very sensible of them. If ill-informed rich Americans start trying to buy the stuff then there won't be any left for poor Indians who need it to treat malaria (for which it actually works). No great shock that Trump's being a bully about it.

Have you been tested? I haven't.

So, your metric isn't a good one, because it's massively distorted by the pattern of testing.

So a country like Zimbabwe is a success because it can not afford testing and no case will be confirmed. Don't worry, we will have plenty of time to test epidemiological models over the coming months.

I'm willing to bet that water and alcohol each kill more. Both are vital in the fight against Covid But the point isn't "what kills most people?", its what "saves more people than it kills" to the greatest extent? If people have bleach, but not peroxide then telling them not to use bleach is a serious mistake.

Do you mean the sulfa drugs? A rather old group of anti bacterials? They are useful in some cases, but they are no use against a virus.
