I want nothing more than an app that attaches Covid-19 test results to mobile phone numbers. If tests are positive, they show up on GPS map. Could be the antibody or virus test, maybe green dots for has antibody and red dots for confirmed Covid-19 cases. There are a few web apps showing cases by county, but we need cases by neighborhood to do it right.

While that might be useful, I'd say that is short sighted.

When life gets back to normal:
Do you share vehicles (bus, train, plane, cab) with others?  How does where they live matter? 
Do you work with other people?   Someone I work with has a 100 mile commute.
Do you attend meetings (church, local government, ...)? 
Do you attend sporting events? 
Do you shop in stores?   I wouldn't begin to guess where the sales clerk at Best Buy lives, or the guy I passed stocking coffee at the grocery store.

I surely don't know the mobile phone numbers of even 0.1% of the people I walked or sat by at Stanford WWB games.

If I look back to say a year ago, I doubt there are but 3 neighbors within 2 blocks that I was within 6' of.
