The Effectiveness of Wearing a Mask Against Covid-19

[userque]

...I have no issue with others wearing them either. If someone wanted to come to the beach wearing a total HazMat suit or a space suit or a gorilla suit, they should do so, as that is personal choice.

This is what I am stating.

I understand. But my question is not about whether you are ok with others wearing them.

Again, I'm trying to understand how you've come to the conclusions you've stated, and I quoted twice, in response to the specific scenario I asked you about.

It seems odd that a logical person would conclude that sunlight would kill the virus while its on it's way to the next person four feet away, which could take less than a few seconds.

Same goes for thinking that the virus can't travel further than "shoulder to shoulder."

Refresher, emphasis added:

Wouldn't that depend on the windiness, crowd size, personal risk factors, and closeness to people outside of your household?

I suppose if people were wall to wall, shoulder to shoulder they might have a use. But people are nowhere near each other. And the fact that the sun's ultraviolet light is on everything, killing all germs, bacteria, viruses...I guess I just don't see the point.

In my mind, clearly, sunlight doesn't "kill all germs, bacteria, viruses" in the environment.

And clearly science and common logic dictates that all viruses can travel further than "shoulder to shoulder."

So again, what am I missing about your understanding of this virus?

So you don't believe that rays from sunlight inactivate viruses or bacteria?

So you don't believe that rays from sunlight inactivate viruses or bacteria?

Not within a time-frame that would prevent others from becoming infected.

That's why I'm asking you to explain how you could believe such a thing...along with my other question.

So its a matter of subjectivity, then. Distance between people, lack of or excess wind speed, interaction, sun strength, etc. All these factor into the time it takes to inactivate viruses on the surface or in the air (which fall to the surface). So you think they wouldn't, I think they would.

That's really all it comes down to. I was there, you weren't. If you want to post an empirical study that allows us to input variables and determine the time to inactivity, I'd happily participate.

What was the other question?

Thanks, nothing further. Things are clear now.

This is critical... do you really know that asymptomatic people spread the virus in significant numbers....
Please show the data on asymptomatic transmission.
All I have seen are models... no real data.
I would love to see those studies.


---
All I have read is that the WHO said the data is hard to find and member countries have reported very little asymptomatic transmission. They said this in a June 5th paper and then a a few days later a spokesperson said it ... but then backtracked.

Then they backed tracked and said...

https://www.statnews.com/2020/06/09/who-comments-asymptomatic-spread-covid-19/



top World Health Organization official clarified on Tuesday that scientists have not determined yet how frequently people with asymptomatic cases of Covid-19 pass the disease on to others, a day after suggesting that such spread is “very rare.”

The clarification comes after the WHO’s original comments incited strong pushback from outside public health experts, who suggested the agency had erred, or at least miscommunicated, when it said people who didn’t show symptoms were unlikely to spread the virus.

Maria Van Kerkhove, the WHO’s technical lead on the Covid-19 pandemic, made it very clear Tuesday that the actual rates of asymptomatic transmission aren’t yet known.

What she said was simple, factual according to the data they had but misinterpreted.

A distinction was made between asymptomatic and pre-symtomatic/a typically symptomatic.

They have records of very few people who have tested positive and never went on to develop symptoms of any kind. These people through contact tracing also appear to not spread virus they can detect.

She was careful but speaking in an expert to experts manner. A doctors idea of asymptomatic is different from they layman.

People are racing to buy face masks amid the coronavirus outbreak, but they probably won't protect you from illness
https://www.businessinsider.com/wuhan-coronavirus-face-masks-not-entirely-effective-2020-1?op=1
Of the many preventative measures you can take to protect yourself from the new coronavirus, wearing a face mask is one of the most visible. But for members of the general public, health experts don't think it'll help much.

"There's little harm in it," Eric Toner, a scientist at Johns Hopkins Center for Health Security, told Business Insider. "But it's not likely to be very effective in preventing it."

This illustration is actually close to the reality.

Notice how in the one mask scenario the smoke never reaches the other person.

Have you ever been tested? Seriously for a moment, you can see its an illustration. Probably cold air, the 2nd person just a mirror flip. You could question if it represented reality but.. You go with what you said?

Do you have a picture that shows the virus going far?
