Tl;Dr: "In conclusion, based on the data collected during the initial deployment of the SwissCovid app, we argue that voluntary digital contact tracing can show similar effectiveness at identifying infected partners of index cases as classic contact tracing." 🙌 /2

There's good observations in here that it's about the entire ecosystem - they had some challenges due to authentication codes not being sent out rapidly and how interoperability is critically important. 🔍 /3

Overall we can't yet prove efficacy, it's too early to conclude one way or the other. But what it does show is that we are headed in the right direction and that this technology has potential. So far, so good! 📈 /4
