Didn't even bother to read the article you posted, huh? That would be expecting too much from you. Well, here are the highlights. And we won't even go into it as a disputed study.
Bottom line?...Wear the damn mask. And quit yer bitchin!
"It is possible that some of the infections may have been caused by removing face coverings for food or drink. Another possibility is airflow, as “direction, ventilation and intensity of airflow might affect virus transmission, even if social distancing measures and mask use are implemented according to current guidance,” according to the CDC report"
"However, the CDC report further explained that it is impossible to evaluate exactly where someone contracted the virus"
“Characterization of community exposures can be difficult to assess when widespread transmission is occurring, especially from asymptomatic persons within inherently interconnected communities,” the report stated".
"Despite this, face masks are still shown to be the most effective means of slowing the spread of the virus, and medical bodies worldwide recommend wearing them and maintaining social distancing measures".
