So most people a lot of people on the forums tend to be around?

I thought psychopaths were into social distancing.

The new article that suggests from German info that masks are more useful than first believed - doubt it, the virus is too small to be efficiently blocked, especially by ordinary masks. Only perhaps helps patients not spread it to others, I presume by slowing down their breath, partially blocking sneezes' velocity as well, etc.

I'm surprised anyone would be willing to sneeze inside a cloth mask. At least inside an FFP2/N95 the surface is away from your face.

The fabric mask just prevents droplets coming out of your mouth from staying airborne.

Gravity handles that. They're promoted due to alleged high levels of aerosolised virus being the culprit behind the spread.

We don't usually notice it but go outside on a cold night and hold up a flashlight when you exhale and you'll see that the amount of minuscule particles is huge.

I've done that same test with a cloth mask. The difference is tiny. In fact I was surprised how little difference it made considering how quickly the inside of the mask becomes an uncomfortably hot, wet environment. Probably the temperature increase amplifying the damp sensation.

A loosely fitted N95 gives the illusion to the wearer of blocking the vapour because it goes out past the edges instead of through the front. Of course loosely fitted they're fairly tolerable. Tightly fitted there is less leakage and they're wearable for a bit longer than a cloth mask, because it takes slightly more time for the internal environment to become unpleasant.

Surgical masks will also redirect the vapour.

It has made me realise that it isn't only the lack of escaping warm wet air that is causing tolerability issues, but also insufficient influx of cool, fresh air.

And could it really make up to 40% "difference"?? (With the spread inevitable anyway, and probably everywhere here by now.) They're not going to convince me.

I think the key there is the up to part. That means it is anything from zero, and 40% could be the best case scenario under ideal conditions. Masks are not standardised nor is fit. Some people can tolerate a thick mask or an airtight seal, others cannot. Some people carefully disinfect and put their mask on before they leave home and don't touch it again until they can perform their decontamination procedures once home again. Others have it lying in their car or pocket and throw it on only when absolutely required, even removing it occasionally while in shops in order to get a bit of much needed fresh air.

Bunch of narcissists then.

After all, narcissists are socialable psychopaths.

Could blood plasma from survivors prevent coronavirus?

Scientists are testing if blood plasma donations from Covid-19 survivors might also prevent infection in the first place.

Gravity does not prevent droplets coming out of your mouth from staying airborne. A mask does this by blocking the path with a material that the droplets stick to.

I've done that same test with a cloth mask. The difference is tiny. In fact I was surprised how little difference it made considering how quickly the inside of the mask becomes an uncomfortably hot, wet environment. Probably the temperature increase amplifying the damp sensation.

A loosely fitted N95 gives the illusion to the wearer of blocking the vapour because it goes out past the edges instead of through the front. Of course loosely fitted they're fairly tolerable.

It has made me realise that it isn't only the lack of escaping warm wet air that is causing tolerability issues, but also insufficient influx of cool, fresh air.

The very reason that "quickly the inside of the mask becomes an uncomfortably hot, wet environment" is because it is filtering out the moisture (droplets) in your breath. If there was no difference then that wouldn't happen.

Obviously the looser the fit, the less effective. The whole purpose of the mask is to filter your breath. Though even if you wear it loosely it will at least direct the vapour away from the person you are talking to.

Laser scans showed that about 2,600 small droplets are produced per second while talking and can float in the air for 8 to 14 minutes. Even a loose mask will act as a shield and prevent much of those reaching the person you are talking to.

I really don't see how you would come to the conclusion that the difference between a mask and no mask "is tiny".

Without a mask your breath is ejected at force and will continue to travel in that direction until air resistance brings it to a halt. That distance can be several meters (or a lot more if there is wind).

A mask will stop that almost immediately and the remaining directional force will be scattered, resulting in a very short travel distance.

So a mask will filter out a large amount of particles and stop the directional force of the remaining ones. That's a huge difference.

#2 in cases and soon to be #2 in deaths.

Interesting about how the R number can misrepresent the rate of infection when small numbers are involved:

I don't get it... How does it misrepresent the rate of infection? The number of cases is irrelevant.

Seems people are somehow getting rate of infection confused with number of cases...?

Experts, analysts, govts, journalists, TV presenters, all can't keep the facts right. How does the average Joe then have a chance?
The point made is you can't go and just use the overall calculation for a large population to try and analyse and decide for a small population what the best reaction should be.

That is exactly why I avoid YouTube videos like I avoid Covid 19.
I can't be bothered to sit through videos and crap just in case I am going to find something useful.

Agreed. Most people (including the experts) cannot wrap their heads around this large scale and evolving epidemic, with its multiplicity of complex technical terminology.

A key point is that statistics always refer to the law of large numbers (bulk data). With small samples, or low rates of infection, the numbers are distorted by random effects and non-uniform distribution.

That is also why medical evidence based on small-scale trials (a few dozen patients), is almost always wrong or misleading.
