1/ Just gave presentation to an advisory board and stressed this point. The first and BIGGEST bang for buck in layered risk reduction is EVERYONE wearing a mask indoors. Not difficult to get 65 to 80% risk reduction w/ this simple act & then layer more on top of that gr8 start. https://twitter.com/kprather88/status/1334198976015261696
2/ Gr8 group. Fun to see viewers on Zoom putting on masks after this point was made! Gave example of close to 95% risk reduction in 4 easy steps. Universal masks, improved ventilation, good portable or centralized filtration, & 1 hr of work day outdoors, even staggered in day.
3/ Both pleased and concerned by one comment that this makes so much sense and that it had not been articulated properly by media or elsewhere. Business leaders, school districts, and (some of) the general public are hungry for SIMPLE steps to dramatically reduce risk.
