Now researchers present an efficient model to study and forecast the spreading dynamics and containment across different regions of the world.

"We discover that social distancing measures are more effective than travel limitations across borders in delaying the epidemic peak," says Professor of theoretical physics, Francesco Sannino, University of Southern Denmark and Danish Institute of Advanced Science, continuing: "The results corroborate our finding that the travel across regions sparks the epidemic diffusion, which then develops in each region independently."
