Instantiation of ideas from the paper here (NOVID app): <a href="https://www.novid.org/" rel="nofollow">https://www.novid.org/</a><p>I attended a talk about this recently, and I honestly think it's a revolutionary / game changing way to do contact tracing.<p>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.<p>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).
