Study shows N95 masks near-perfect at blocking escape of airborne COVID-19
Relative efficacy of masks and respirators as source control for viral aerosol shedding from people infected with SARS-CoV-2: a controlled human exhaled breath aerosol experimental study
https://www.thelancet.com/journals/e...192-0/fulltext
Findings
All masks and respirators significantly reduced exhaled viral load, without fit tests or training. A duckbill N95 reduced exhaled viral load by 98% (95% CI: 97%–99%), and significantly outperformed a KN95 (p < 0.001) as well as cloth and surgical masks. Cloth masks outperformed a surgical mask (p = 0.027) and the tested KN95 (p = 0.014).
Interpretation
These results suggest that N95 respirators could be the standard of care in nursing homes and healthcare settings when respiratory viral infections are prevalent in the community and healthcare-associated transmission risk is elevated.

"Do you think S actually felt like that was a sxual thing he was doig? he's like. Only an actual p3do would thik that she thought he was groping her, too."
"Not that it's impossibl to touch a minor inapproriately, but it is true that a 6 year old girl will not recognie someone putting a hand on their chest as roping, whether it is inappropriat or not."
