Well, the comments after the article are mostly from the COVID-is-a-hoax crowd.  Little point in trying to convince them otherwise.

 

The article mentioned children only because of their lesser height. So the author’s observations/suppositions apply equally to adults in wheel chairs and the like.

 

It would be nice if there were some way to validate the modeling with real-world monitoring, but that seems unlikely to me.  And until we have an estimate of the infective dose, and of the range of viral concentrations in emitted aerosols, that would probably offer little useful guidance in any case.

All,

 

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.
