Will review the study in depth in the future.
But at face value this demonstrates how enhanced ventilation (clean air standards) alone is insufficient to prevent viral illness. Improvements - absolutely, but won’t mitigate it alone.
That instead we will need a layered mitigation approach.

Three Democratic former presidents led a wealth of tributes on Tuesday to Jesse Jackson, a “titan” of the civil rights movement and “one of America’s greatest patriots” who has died at the age of 84.
The former US president Joe Biden said history would remember Jackson as “a man of God and of the people”, calling him in a post on X: “Determined and tenacious. Unafraid of the work to redeem the soul of our Nation.” Continue reading...
