(Author’s note, this article is a bit out of date but I just found this draft and am posting it because I think it’s still an interesting study)
Trying to get outside my microbiology comfort zone and post some more about building science. A recent study finding that more fresh air in classrooms correlated with fewer absences definitely caught my attention. The causation (if any) behind this correlation is unknown and but may very well be microbial. After all, which is more likely to make you sick… air full of microbes shed by other people or air from outside the building?
