One recent study found that SARS-CoV-2, the virus that causes COVID and its many variants, actually isn't as infectious as "the science" - and, more importantly, the government authorities like Dr. Anthony Fauci - would like the public to believe.
Offering yet another example of how lingering in enclosed spaces doesn't dramatically increase an individual's risk of contracting COVID, Coronavirus loses 90% of its ability to infect us within 20 minutes of becoming airborne - with most of the loss occurring within the first five minutes, the world’s first simulations of how the virus survives in exhaled air suggest.
Professor Jonathan Reid, director of the University of Bristol’s Aerosol Research Center and the lead author of this study, explained why lingering in poorly ventilated spaces isn't as risky as scientists would have us believe.
Most of this decline in viral infectiousness was gleaned from a study whose authors described it as the world’s first simulations of how the virus survives in exhaled air suggest.
Interestingly, this means that ventilation, once thought to be the most effective way to ignore the physical distancing and mask-wearing likely to be the most effective means of preventing infection. Ventilation, though still worthwhile, is likely to have a lesser impact.
"People have been focused on poorly ventilated spaces and thinking about airborne transmission over metres or across a room. I’m not saying that doesn’t happen, but I think still the greatest risk of exposure is when you’re close to someone," Dr. Reid said. "When you move further away, not only is the aerosol diluted down, there’s also less infectious virus because the virus has lost infectivity [as a result of time]."
This latest study completely contradicts previous research conducted by scientists in the US, which purported to show that particles containing the virus that causes COVID could still be found lingering in the air.
Here's more from the Guardian and Dr. Reid.
Until now, our assumptions about how long the virus survives in tiny airborne droplets have been based on studies that involved spraying virus into sealed vessels called Goldberg drums, which rotate to keep the droplets airborne. Using this method, US researchers found that infectious virus could still be detected after three hours. Yet such experiments do not accurately replicate what happens when we cough or breathe. Instead, researchers from the University of Bristol developed apparatus that allowed them to generate any number of tiny, virus-containing particles and gently levitate them between two electric rings for anywhere between five seconds to 20 minutes, while tightly controlling the temperature, humidity and UV light intensity of their surroundings. “This is the first time anyone has been able to actually simulate what happens to the aerosol during the exhalation process,” Reid said.

Another iconoclastic finding from the study: the temperature of the air made no difference to viral infectivity, contradicting the widely held belief that viral transmission is lower at higher temperatures. This would seem to contradict the seasonality of the virus, a pattern that has held for the last two winters.
The study hasn't yet been peer reviewed, but we imagine scientists will be quick to scrutinize its findings - particularly the findings that contradict the research conducted by other research.
I thought it could survive up to two weeks on a flat surface.
I wonder if it varies on the variant?
Now in a hospital is different because there are...and all within a few minutes....several people in the same space.
“...particularly the findings that contradict the research conducted by other research.”’
But...but...but...Herr Mengele-Fauci says the SCIENCE IS SETTLED!
“This would seem to contradict the seasonality of the virus, a pattern that has held for the last two winters.”
My understanding is that some viruses proliferate in the winter because people tend to remain indoors together for longer periods in that season, not because of the outdoor temperatures.
It was widely stated at the beginning. That’s why all the retail spaces were always being cleaned (supposedly).

There would seem to be a problem with this theory, given that it is inhaled and exposed to air inside the lung for X minutes before it ensnares in a receptor point.
They bounced around a lot throughout.
The CDC has been chastised on just about every point.
I follow Dr. Ashish Jha at Brown...AND his resume says he is an actual Pandemic expert AND a practicing physician...I believe at the Vet Hospital in Providence.
IOWs the masks protect the virus more than the people wearing them.
They were Pimping that narrative pre-lockdown.
About the same time all the relevant Gov’s of the world were stockpiling large amounts of tablet Iodine.
I think Late January ish.
20 minutes? That’s no comfort.
“Lockdowns macht frei “
Why stockpile tablet iodine?
I assume they figured it’d help against Covid.
No clue, I remember it because it struck me as off/odd.
Governments stockpile iodine tablets as prepping for radiation exposure.
. . . and leap 40 feet at a time.
