Infected after 5 minutes, from 20 feet away: South Korea study shows COVID-19’s spread indoors
The Seattle Times ^ | December 10, 2020 | Victoria Kim

Posted on 12/10/2020 7:19:37 AM PST by Pontiac

“In this outbreak, the distances between infector and infected persons were … farther than the generally accepted 2 meter 1/8 6.6 foot] droplet transmission range,” the study’s authors wrote. “The guidelines on quarantine and epidemiological investigation must be updated to reflect these factors for control and prevention of COVID-19.”

“There’s a real misconception about this in the public.” said Seung, who was not involved in the South Korea study. “They’re thinking, if I’m not a close contact, I will magically be protected.”

Linsey Marr, a civil and environmental engineering professor at Virginia Tech who studies the transmission of viruses in the air, said the five-minute window in which the student, identified in the study as “A,” was infected was notable because the droplet was large enough to carry a viral load, but small enough to travel 20 feet through the air.

Don’t try to distract people with fancy words like viral load, just wear the damn mask! Else we’re telling!

And we will give you dirty looks. Boy will we!

[If masks are not effective when the wearers are 20 ft. apart, they are truly worthless.]


That’s like saying since locks can’t prevent home invaders from breaking down your door, they’re truly worthless. Or that since tanks can’t prevent all RPG’s from penetrating the hull, tank armor is truly worthless. Masks improve your odds and lower the dose. Are you bullet-proof, in viral terms? No. But I think of masks in the way that tankers thought of improvised, hillbilly armor that improved their odds without making them invulnerable. Every advantage is worth seeking out when the threat is an early grave and the prize is staying alive.

Are they an annoyance? Absolutely. I don’t like seat belts either. But the thought of flying through my windshield in the event of a serious collision means I always click it.

Soon, a person might, might mind you, have an infinitesimal small chance of ingesting or inhaling enough virus from 25 feet away that they get sick and face an infinitesimal small chance, .6%, of dying, and we need to shut the world down?

There is no way society can protect itself from this virus or probably any other.

Bingo. All this mask wearing and social distancing nonsense is all for show to give people the "feeling" they are doing 'something'.

Did they define “infected”? In other words, did the virus show up after 40 cycles of the pcr test? Did it make him sick? Was there enough of a viral load that his body didn’t fight it off?

Buried in the last paragraph of the article: “The high school student and a third diner who was infected had been sitting directly along the flow of air from an air conditioner; other diners who had their back to the airflow were not infected.”

Typical reporting designed to scare people. The guidelines are sufficient as long as one doesn’t sit downwind from a high speed virus spreading fan.

Just riot and loot. You’re protected against the virus.

I would but I tire easily.

Have you got anything more sedentary?

Technically it isn’t alive.

Exactly why we have rampant cases of smallpox and polio and whooping cough all over the US to this very day! because there is no way society can protect itself from a virus!

Pandemic doesn’t mean everyone dies. It means the disease is prevalent across the country and/or the world.

We’ve had about 50 million people infected in the US so far. I’d say that’s pretty darn prevalent.

Will just a 99.8% survival rate and that with the democrats blocking known medicine for a cure!

It is about control and making billions by destroying business. They shutoff water to Calif central valley to drive down land prices so insiders could buy land cheap to sell the right a way for the train to no where.
Insiders will buy up properties of out of business owners to make billions.

Yours is a great example of the faulty logic that has put us where we are.

The best logical conclusion from this test, if we are going to accept the test as sound, is that all air conditioners should take in fresh air constantly so as to introduce only uncontaminated air into a building.

Also all central air conditioners should be modified so as to self disinfect.

Expensive, but certainly less costly than shutting down our economy.

Also how to manage air flow in public buildings would be a reasonable endeavor.

You can wear your mask if you choose, but my body, my choice. I choose to protect myself in other ways.

"99.8% survival rate"

IFR is 0.65%, so survival rate is 99.35%

"It is about control and making billions by destroying business. They shutoff water to Calif central valley to drive down land prices so insiders could buy land cheap to sell the right a way for the train to no where. Insiders will buy up properties of out of business owners to make billions."

No argument about the response being an utterly botched effort with nonsensical policies that have led to death, destruction, and economic catastrophe. But the virus is still real and it's still killing people. In fact, those failed responses from governors and health departments have made things WORSE than they would be otherwise. For example: Governor Cuomo and Governor Newsom forcing nursing homes to accept known-infected patients. That along cost the lives of tens of thousands of defenseless seniors. For that, they should be facing tens of thousands of cases of negligent homicide.

Don't confuse a very real virus that's spreading, putting people in the hospital, and killing some people with a response from government that's completely and utterly failing to address that situation appropriately. The virus is separate from the response.
