She says 'screw the masks' during a global pandemic because she's worried about how she looks folks.

Meanwhile, out in the real world:

"During a COVID-19 outbreak on the USS Theodore Roosevelt, persons who wore masks experienced a 70% lower risk of testing positive for SARS-CoV-2 infection." https://jamanetwork.com/journals/jama/fullarticle/2776536

"This work shows that both theoretical and empirical evidence is consistent with masks protecting against respiratory infections" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8499874/

"Our review of the literature offers evidence in favor of widespread mask use as source control to reduce community transmission: Nonmedical masks use materials that obstruct particles of the necessary size; people are most infectious in the initial period postinfection, where it is common to have few or no symptoms (45, 46, 141); nonmedical masks have been effective in reducing transmission of respiratory viruses; and places and time periods where mask usage is required or widespread have shown substantially lower community transmission." https://www.pnas.org/doi/10.1073/pnas.2014564118#sec-11

"Experimental and epidemiologic data support community masking to reduce the spread of SARS-CoV-2" https://www.cdc.gov/coronavirus/2019-ncov/science/science-briefs/masking-science-sars-cov2.html#anchor_1619457332454

"The study results shed light on the importance of using masks by individuals infected with SARS-CoV-2 and show that different types of masks can help block viral transmission." https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0264389#sec011
