One of the greatest challenges with COVID is forecasting where communities are in the transmission curve.   Most of our models look backwards, not ahead.  It was like knowing where a hurricane had been, but not having a forecast of where it was going.  

Carnegie Mellon University researchers are trying to change that.  The Delphi group at CMU is at the forefront of epidemiological forecasting using real-time information on symptoms, doctor visits, medical tests and searches on Google and Facebook. It provides a county-by-county sense of COVID is surging today and where it may be tomorrow.
