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).
