And if the prerequisite to be a contact is more than 5 minutes close to a person, that tells you it's never going to work. You can spread the virus to 100 people a day and never be around any of them more than 5 minutes.
How did South Korea know who to test?

They did Contact Tracing of positive cases...

Ebola has a similar dormant period (2-20 days) as Covid-19. But, so far, is body fluid transferred.
