The tricky math of lifting coronavirus lockdowns

Researchers are using mobility data prior to the lockdown, and comparing it to the current mobility numbers to determine how to emerge from the lockdown without triggering major resurgence in the outbreak. The researchers admit that their conclusions are highly uncertain and more data is needed.
