Airborne transmission of Covid
Source
As a nuclear engineer who has studied how long radioactive particles stay in the air, I am aware that very tiny particles can stay in the air indefinitely. For example, radioactive particles from Chernobyl (1986) are still in the atmosphere.
This may have very negative implications for reopening casinos.
Also, face masks are probably more important to reducing infection than has previously been claimed.
It's coming for you!

Quote: gordonm888As I have long suspected, it may be true that the virus is transmitted through the air. Small droplets stay in the air much longer than large droplets (standard aerosol physics) and people exhale a broad distribution of water droplet sizes. Scientists are now claiming that indoor transmission through the air can occur at distances longer than 6 feet. Indoor ventilation systems would benefit from high efficiency HEPA-style filters.

Something to consider is, humans aren't exactly a Teflon vent to infection.
Consider:
Quote:The average person generates more than a liter of mucus a day, including snot, saliva, cervical mucus, as well as protective coatings for the digestive system, urinary tract, lungs, nose, and eyes. Mucus covers 400 square meters of surface area in an adult body, roughly the same area as a basketball court.
Mucus is over 90 percent water, but it also contains fat, salts, proteins, various immune cells, and mucins. A mucin is a protein covered in chains of sugars that stick out from the mucin molecule like legs on a centipede. Mucins give mucus its slippery feel and are very effective at binding together to form gels, which enables mucus to create a strong barrier against microbes and irritants.
Mucus performs a number of important functions to keep the body safe from infection. New microbes constantly attempt to invade the human body, many of them disease-causing pathogens. When fragile parts of the epithelium — the outer layer of skin and the linings protecting organs — crack, microbes have an easy access point. To prevent this, mucus keeps the epithelium well-lubricated. Mucus also coats the existing entry points into the body, such as the nose, mouth and stomach, and catches pathogens that try to get in that way. The mucins form a powerful sticky mesh, like a glue trap that the invading microbes get stuck in, preventing them from moving any farther into the body. Then antibodies, immune cells, antimicrobial proteins, and bacteria-infecting viruses contained in mucus can kill the pathogens or isolate them to prevent them from building up.
I wouldn't be surprised if many of us have already encountered small amounts of the virus. It just wasn't enough, or just right to get past our multiple defenses.
Of course it stands to reason, you'd want to reduce time and exposure.
I don't know if that story about cigarette smokers getting covid less panned out, but consider.
Quote:When you smoke, the cells that produce mucus in your lungs and airways grow in size and number. As a result, the amount of mucus increases and thickens.
Probably not a good plan. Once your lungs are damaged enough, you have a harder time expelling that mucous.

Scottsdale requires masks.
I wonder if she was wearing one.

A picture is better than 1,000 words....another 52,228 Americans bit dust (aka the covid19) in 1 day. When will they ever learn? Use commonsense for commongood. Wear a n95facemask and protect yourself from covid19 as if it were the air-borne-EBOLA.

I guess all those ideas about a booming economy didn't quite work out they way they envisioned
People aren't responding to your bait because to respond isn't politically correct on this forum. So people won't respond and will just post elsewhere.
Quote: KeyserThe reopening of the economy wasn't the problem. The riots/protests were the problem, not because some ma and pa pastry shop reopened.

Reopening the Casinos was a big step backwards IMHO. Casino industry should have stayed shutdown until further notice when the contagion seem to be fully under control (probably at least an year after the initial outbreak).
Quote: gordonm888Anyone have any recommendations for protective face masks better than simple surgical masks? I've read about N95 masks but am concerned about them not being reusable.
I use a steamer/pressure cooker to kill germs on my "reuseable" n95facemasks. I set the auto-steamer for 1 minute. So far so good. My brother didn't care about the covid19 stuff. His whole family got sickened with covid19. Go figure.
Here are photos of my steamer/pressure cooker

I think the surgical masks are not enough, but might suffice where there's no one around. The surgical masks are to protect others from you. The N95 masks are to protect you from others as well as protect others from you. You've got this virus hanging out in the air for hours and an N95 mask is the minimum mask that approaches blocking that.
I'm not sure using a public restroom is advisable anymore either. Will have to wear a mask there too.
Doctors and nurses are supposed to dispose of their masks after each patient, but because of the severe lack of PPE by the federal government, they are being forced to keep using them long past sanitary conditions, like one mask for a 40 hour work week. Navarro said he ordered 20 million N95 masks, so that is near 100% short of the billions of N95 masks needed. #StayHome

In Vegas...just to play it safe, masks should have been mandatory from the start. Governor made a big stink about fearing violence (someone was shot in Michigan?)....so he passed on making it mandatory.
Now, it’s mandatory and probably too little too late.
At worst....he could have made it mandatory for 2 months and see where the numbers go. Then re-evaluate.
He made a mistake, IMO.

Yes, a security guard in Michigan was MURDERED over telling them they had to have a mask on. Hope those evil people get Covid-19 and die in prison.

Quote: ChoneWilsonThe most effective protective defense against The Coronavirus appears to be the Gas Masks.
I agree, but our Governments can not even order 3M, J&J, DuPont, etc.. to produce enough of n95facemasks to protect all American Citizens. Gas Masks would be impossible to mass produce, right?

There are plenty of high quality N95s out there right now. They're in stock in most grocery stores. And medical supply stores will sell them in bulk. They run between 3 to $5.

Wow, even grocery stores sell N95facemasks in your neck of the woods. That's very good for you guys in your area.
Unfortunately, in my neck of the woods, no can do. For example, NOT EVEN the almighty HomeDepot has n95facemasks to sell. It apologizes for not able to sell N95facemasks to its customers because of shortages, i.e., Medical professionals, EMT guys, Cops, Firemen... need the n95masks more than you and me. It gets NO N95FACEMASKS TO SELL TO THE PUBLIC. It's just another facts of life stuff... What else is news? Governments have screwed up BIG TIME since Jan 2020.
I kid you not. Here is a proof that HomeDepot went out of n95facemask:

Where is "your neck of the woods?" In the US, right?
Or something of that nature.
Quote: KeyserI haven't tried looking at Home Depot.

Right, I've lived in the good old USA. By the way, coffee filters come in handy when it's used in conjunction with a n95facemask. You see... I can not change the n95facemask when ever I get sweaty in a casino, but I can frequently change a coffee filter which serves like a Disposable Toilet Seat Cover.

And that's how we build immunity.
Not by hiding, but by circulating
and getting small pieces of it. You
can't hide forever in your basement.

Yeah you can.
Works out really well for some people!
I don't know if you're staying sheltered, or what your situations actually is, but I'm seeing masks for sale everywhere. Even stands in gas station parking lots and inside the station. So why on earth are you trying to wear a coffee filter?
It doesn’t have to be sterile. You can reuse masks without cleaning.

So why on earth am I trying to wear a coffee filter[inside of my N95FACEMASK] ?
Well, a picture is better than 1,000 words. Look at the picture, and think of an answer (Hint: why do you use a Disposable Toilet Seat Cover?)
