(Covid-19) Flipping the Perspective in Contact Tracing [pdf]

I attended a talk about this recently, and I honestly think it's a revolutionary / game changing way to do contact tracing.
TLDR is to understand the spread of COVID-19 around you (through second-order network connections and beyond). This makes it much more similar to a weather forecast (e.g. the virus is approaching your vicinity through people in your network). This makes it a much more effective way to systematically identify, isolate, and contain further spread.
The idea is so simple and effective, I can't believe this isn't front and center over the news as a way to effectively contain the spread of COVID (beyond the existing measures of wearing masks, social distancing, etc).
