If some organization had perfect knowledge about the location of each person on earth (at any moment); and got an immediate update on any person that is diagnosed with the coronavirus, how much difference could that make in preventing the spread of the coronavirus?
What if the only type of action that the organization could take is sending people messages? For example, if Alice was just diagnosed with the coronavirus and 10 days ago she was on a bus with Bob, now Bob gets a message: “FYI the probability you have the coronavirus just increased from 0.01% to 0.5% due to someone that was near you 10 days ago. Please self-quarantine for 4 days.”
(These numbers are made up, obviously.)
