No matter what opinion you have there is probably a study that supports that opinion. :facepalm:

The folks in Asia deal with this stuff all the time - the first thing they do ? Put on their masks. :rolleyes:

No I read a study on masks before I commented the masks do not stop the spread. Microbe size and coverage. If you can smell thru the mask the virus can pass cloth masks do not meet contained virus standards.

This isn't true. 1, no such thing as "contained virus standards". 2, cloth masks are not meant to protect you, they're meant to contain droplets FROM you. 3, nothing is 100%. The idea is that you want to decrease the spread. 4. Microbe size is irrelevant. The virus is traveling on droplets, which are larger when first expelled. Once it's in the air, the droplet size is smaller. When you cough or sneeze, there is potential for aerosolization, at which point you can kiss your 6ft rule goodbye. At that point a respirator or n95 is required by others around you.

Honestly , I’m sick of the whole thing .
Sick of talking , reading , hearing , and arguing about this whole mess . Sick of the night shift , remodeling hospitals , dealing with contractors ,and dealing with idiot crew members . It’s freaking pouring down rain and I have to go a good ways to my truck .
Gotta wait it out or get soaked . Neither one is a good choice .. Sleep deprived rant is over now .
btw , the glass is still half full ..
night everyone ..

interesting article from wedmd


Are Masks a Kind of Vaccine Against COVID-19?
By E.J. Mundell
HealthDay Reporter
WEDNESDAY, Sept. 9, 2020 (HealthDay News) -- The world is still waiting for a safe, effective coronavirus vaccine. But new research now suggests that billions of people may already be using a crude vaccine of sorts: face masks.

The theory -- and it remains largely a theory -- is that by filtering out airborne coronavirus droplets and thereby lowering the dose of SARS-CoV-2 a person inhales, infections have much less chance of producing symptoms.

Much in the way vaccination works, an immune response would be triggered in the mask-wearer upon contact with a small amount of virus, but at a level that's not likely to cause serious illness.

"If this theory bears out, population-wide masking, with any type of mask that increases acceptability and adherence, might contribute to increasing the proportion of SARS-CoV-2 infections that are asymptomatic," said Dr. Monica Gandhi and Dr. George Rutherford in a commentary published Sept. 8 in the New England Journal of Medicine. Both authors are from the University of California, San Francisco.

There's some good evidence that masks could be working in this way, according to the two experts. They pointed out that animal studies conducted since the 1930s have borne out the notion of a "lethal dose," or how many viral particles are needed to cause severe disease.

More recently, studies conducted in hamsters seem to show that "higher doses of administered virus led to more severe manifestations of COVID-19," Gandhi and Rutherford wrote. And when the hamsters were protected with simulated masking, they "were less likely to get infected, and if they did get infected, they either were asymptomatic or had milder symptoms than unmasked hamsters," the experts noted.

For ethical reasons, similar trials in humans haven't been conducted. But population studies seem to support the "mask as vaccine" theory. For example, the U.S. Centers for Disease Control and Prevention reported that by mid-July about 40% of coronavirus infections were asymptomatic, but in areas of the United States where mask wearing was very prevalent, that number rose to 80%.


In early outbreaks of SARS-CoV-2 infections on cruise ships, before the widespread use of face masks, the rate of cases with no symptoms was about 20%, Gandhi and Rutherford noted. But in an outbreak on one Argentinian cruise ship where face masks were mandated for passengers and crew, the rate of asymptomatic cases rose sharply, to 81%.

Finally, in two recent outbreaks in U.S. food-processing plants where workers were told to wear masks, 95% of cases of coronavirus infections were asymptomatic, and the remaining 5% experienced only mild-to-moderate symptoms, the two experts said.

Dr. Amesh Adalja is an infectious disease expert and senior scholar at the Johns Hopkins Center for Health Security in Baltimore. Reading over the NEJM essay, he agreed that "if facial coverings decrease the amount of virus a person is infected with, they can provide a way of tilting towards infections that result in minimal or no symptoms, yet induce some degree of immunity."

But experts caution that in no way should masks be viewed as a substitute for a safe, effective vaccine.

Speaking to the New York Times, Emory University vaccines expert Jyothi Rengarajan noted that inhaled exposure to even small amount of live virus is a much riskier proposition than the more controlled effects of a vaccine. That's because there are variations between individuals in immune responses, genetics, and even the structure of the nasal passages, she said. So even when wearing a mask, it's still possible that inhalation of SARS-CoV-2 could still make some people very ill.

However, masks certainly may cut down on that risk. And as the world waits for a vaccine, "any public health measure that could increase the proportion of asymptomatic SARS-CoV-2 infections may both make the infection less deadly and increase population-wide immunity without severe illnesses and deaths," Gandhi and Rutherford concluded.

Sturgis? I heard about it. Haven't read the story, but how on earth can they say 250k..... I'll read the story now....

I heard about Sturgis. It has been reported all over the media. They are all nice people out sharing a common interest.

The other current media events are the riots, looting and burning that are happening in many cities. They are not nice people.

It seems logical to me that if Sturgis can spread the virus, why can't the rioters also spread it to the same degree? Why aren't those statistics being tabulated as well?

Because the media and those that control the media only tell us what they want us to know. One can protest with thousands of others, yet churches can only be at 25-50% capacity with social distancing. Some have yet to open and some have drive up services. Forget funerals and weddings. But, protest and riot all you want .... Portland has been rioting all summer yet for the most part the mayor and governor have done nothing to stop it.... That's just sad....

Probably more like mostly poor, black rioters will not show up to get tested and even if they do less likely to self report they were at a riot?

Older, wealthier mostly white people will use their insurance to go to the doctor and self report their past non illegal activities.


Blame media or blame human behaviour. I choose the latter - mostly because the media in general sucks.

No worry, Musky. I let some out as well and it was more than just the two of us. Giving a little leeway didn't work.
