RE:ApplicationYou need to do you DD but in a nutshell, the federal government in Canada has already committed $2B.
The practical way I see this working is when Covid is detected, the people on the plane or bus or classroom get isolated and tested.
The people who test positive now know they are positive and need to self isolate for 2 weeks and likely notify others they have been in contact with. The ones who are negative are lucky... not sure the protocols have been determined yet on the ppl who tested negative.
Maybe self isoldate and do a follow up test 2 days later.
I see this working in conjuction with the quick test to test who is actually infected.
