New COVID surveillance predicts direction, speed and acceleration of virus

(Northwestern University) A new COVID-19 global surveillance system has been developed which can dynamically track not just where the virus is now, but where it is going, how fast it will arrive and whether that speed is accelerating. The new system, the first to dynamically track the virus, is being rolled out in 195 countries Dec. 3. It also will dynamically track the virus in individual U.S. states and metropolitan areas and in Canadian provinces.
