Harnessing wearable device data to improve state-level real-time surveillance of influenza-like illness in the USA: a population-based study - ScienceDirect

I honestly don't hav the background to parse the findings completely on this, but the concept is very compelling. Apple could release an Apple Watch app that collects data from millions of people in real-time to feed predictive models of Covid-19 spread. If that app was out there, I would install it immediately. I wonder if they are working on something like this right now. Thanks to Nick Swenson for the link. 🦠
