Their work was to establish whether transmission was long range. They established it was short range. They did not establish it was fomites. We already know that respiratory droplets are the primary culprit and aerosols are a less common, but still important culprit. Still zero cases demonstrating anything other than those two modes of transmission.

This is a dermatologist writing an article in May 2020, before fomites transmission was determined not to play any major role (or literally any known role whatsoever) in transmission. The dermatologist is parroting what the CDC and WHO were saying at the time based on lab work demonstrating that seemingly viable SARS-CoV-2 virions could survive on surfaces for a period of time. Still zero documented cases of fomite transmission.
“Prolonged Infectivity of SARS-CoV-2 in Fomites”
This was laboratory work looking at the stability of the virions in a laboratory controlled setting. From that article: "Accordingly, it is plausible that fomites infected with SARS-CoV-2 play a key role in the indirect transmission of coronavirus disease (COVID-19)." In other words, in theory, it's possible. Sure. Still zero documented cases of fomite transmission.
"https://www.cdc.gov/mmwr/volumes/69/wr/mm6914e1.htm"
Again, this is speculation only. From the article: "the possibility of indirect transmission through fomites by presymptomatic persons is also a concern. Objects might be contaminated directly by droplets or through contact with an infected person’s contaminated hands and transmitted through nonrigorous hygiene practices." The article is focused on pre-symptomatic spread; not fomites in particular. So again, zero documented cases of fomite transmission.
“Most transmission appears to have occurred through close contact and fomites.”
Where are scientifically documented cases of airborne transmission? And that masks stop it?
Good luck.
