Ah but you forgot about Group G:
The myriad of individuals that could unknowingly carry the virus that you encounter during a duty such as security staff, dispatchers, engineers and catering staff and frankly, anyone at all that will be within very close proximity to you or has touched something that you later touch yourself. How do we isolate ourselves from those unsuspecting biological villains?
Do you think those filthy trays at security that you put your iPad and liquids in have ever been cleaned, never mind disinfected?
