Thanks, John.  Those slides are now in one of the ppts.  That is VERY helpful.  

And good news yesterday.  The Am Federation of Teachers in DC issued my ventilation paper under the title "K-12 and Higher Education Leader Bulletin No. 9   Ventilation Basics"  and handed it to the Biden transition team as their recommendations. The Assistant Director said they hurried the publication because "the Biden transition team was "anxiously awaiting it."  Well, DAMN!!

 If any of you guys want an official copy, just email and I'll attach one for you.   Monona

Up until now,  we have generally considered face-to-face viral transmission of COVID-19 and dispersion into closed or open spaces accordingly.

Please look at the attached study as it relates to infected individuals and the trail as they walk and states that that (young) children are most vulnerable taking into consideration their height.  It, however, does not discuss how this impacts unfortunate adults who are physically challenged and must use wheel chairs or medical motor scooters or have growth or musculoskeletal disorders.  Also, you can review the comments at the end.


Be Safe and Stay Healthy!

All My Best and Happy Holidays,
