COVID-19 Instant Screening test, page-605

I think you should have a think about how long it would take for everyone to get access to, and use, an instant Covid test on their phone for $1 and do the math.... around the world.

Once approved access to all can happen very quickly. ALL.

This could all happen extremely fast for multiple reasons - the main ones being :-
instant results,

remote results,

billions saved by individuals, businesses and govts

and a dramatic reduction in testing waste...

Things often move slow but the Chines have shown you can build a working hospital in a day or so from scratch...... Organising a phone to cough into is a lot simpler and easier.
