1/ We need to find ways to allow society to function and yet keep R0 below 1. One key part of that is to avoid breathing in air that others have exhaled. Where is that easiest to do while still interacting with other people? Outdoors.
2/ For example, imagine a lower risk trip to the dermatologist. In warm enough areas the office could be moved to a field with curtains on poles for privacy. The sky above and possibly fans blowing would reduce risk of virus particles.
3/ The stay at home message is too simple. We need to shift more work outdoors and can reboot parts of the economy if we do. Air outdoors dissipates the virus particles. Going outdoors in crowds is risky. But lots of commercial services are delivered one-on-one. Move it outdoors.
4/ We can deliver more services outdoors and do more buying and selling outdoors. Granted this approach doesn't sound viable in Manhattan. The place is much too dense. But it would work in rural and many suburban areas. In some cases the business might need to move a few miles.
5/ Lower density outdoors approaches would work for much food selling. Put farmers markets in very large otherwise empty parking lots or fields. Put each stall 100 feet away from other stalls. Require face masks of course.
6/ For things that must be done indoors HEPA filter boxes should be deployed along with window fans. Windows with HEPA fans blowing inside into a dentist office would be good for pulling in fresh purified air.
7/ There is not a single simple adaptation sufficient to let everyone leave lockdown. But moving work outdoors would work in some cases. Other approaches such as more drive-through bank tellers and other forms of drive-through are needed too. So are #Masks4All and #Testing4All.
