Is There a Predictive Effect on Infection Rates?

People will continue to move in certain ways that's really difficult to restrict. It's not often something like a gravity model where you might say that this urban centre in the middle of the spatial model is just sort of radiating out. People obviously going to certain places and don't like going to other places. And perhaps most importantly, when things like disasters or sort of these exogenous effects come into place, it's good to know where people usually go at a given time period and how that's changed now.
