I’m proud to have our latest research published on how long #SARSCoV2 remains infectious while airborne! We studied the fundamental processes that drive the loss of viral infectivity in the aerosol phase. #COVIDisAirborne
Here’s a thread going over some of the findings.
@ParentMishmash Interesting question btw. Actually, all of your questions have been. Thanks!
@J__Doh Here are the specific values. So, about 10 to 20 times faster decay in sunlight (depending on the season).

Prior to 2022, airborne viral decay was described in terms of half-lives, and on the order of hours. Famously, it was reported that SARS-CoV-2 had a half life of 1.1 hrs and could remain infectious in the air for 16 hrs.
A paper was published that presented a new model to predict airborne disease transmission. There were many features included in this model that make it interesting.
I have some thoughts.
Context: Why do people think knowing the CO2 concentration is important when it comes to Covid transmission?
There are 3 unique reasons.
1) Both CO2 and respiratory (virus containing) aerosol are exhaled. They are, to some degree, correlated. Meaning that if the CO2 concentration in a room is high, the amount of exhaled aerosol in the room may also be high.
You have no idea. Ironically, I found out about this letter when I was on my way to a dinner to celebrate the end of a 5 year covid project I was on. This project resulted in 14 papers in high impact journals where we explored how SARS-CoV-2 is aerosolised through talking/singing
Needless to say, to find out right then that the government had produced this letter was bizarre and upsetting. Like, why are we doing all of this research if they are just going to ignore it?
When I shared the letter with others on the team, it got a little awkward....
I literally posted this right after I left (hence the tone...).
