Extremely irresponsible article in the Guardian today---cites a simulation-based study as if it proved the risk of transmission at > 6 feet is negligible and Covid quickly loses most of its infectiousness once in the air, so we should only worry about face-to-face contact and improving ventilation would not help much... but fails to mention that the simulation did not include omicron until the very end of the article.
That should have at least been in the opening paragraph, and probably in the title. (Also, the study hasn't been peer reviewed....)
On top of that, the original article falsely claimed the study found 'Covid loses 90% of ability to infect within five minutes'---which they've now corrected to 20 minutes. WTF.
'Covid loses 90% of ability to infect within minutes in air – study
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.
The findings re-emphasise the importance of short-range Covid transmission, with 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," said Prof Jonathan Reid [seems completely irresponsible to say this in the midst of the omicron spike without mentioning they didn't include omicron in the simulations] [...]
"It means that if I'm meeting friends for lunch in a pub today, the primary [risk] is likely to be me transmitting it to my friends, or my friends transmitting it to me, rather than it being transmitted from someone on the other side of the room," [...]
[...] They hopes to start experiments with the Omicron variant in the coming weeks.'
