[CED/CD/EAT] Update on aerosol sars cov2 transmission and ventilation

Wed Jan 6 17:05:42 MST 2021

Excellent. Thanks Jeff.

My mask protects you; your mask protects me. We've controlled infectious diseases without vaccines for thousands of years. Wearing our masks means we can have a functioning economy and concurrently save thousands of lives.

All UA employees, students and visitors must wear a face covering inside all UA buildings, unless alone in a single occupancy office, and in UA outdoor spaces where continuous physical distancing of at least six feet is difficult or impossible to maintain.

Similarly, I received this summary today that was provided by a colleague here at the UA who is working in this arena. It is authored and updated in multiple languages by the members of a National Academies panel.

A UA team is working on this and making it into bilingual webinars for the general public. Stay tuned.

I know that some of you have a particular interest in this issue and the attached is as good an update in one place as any. It doesn't address the more infectious virus variants such the one that has become dominant in the UK.

Shane
