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

Travel bans will delay the peak of infection with days, while social distancing has a much stronger impact, amounting in up to 4 weeks delay, scientists report.

"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, the University of Southern Denmark and Danish Institute of Advanced Science.

"The results corroborate our finding that the travel across regions sparks the epidemic diffusion, which then develops in each region independently."

Virus-induced pandemics like COVID-19 are a threat to humans not only because of the number of human lives taken but also because of the profound and long-lasting impact on the economy and social dynamics.

While different empirical models already exist to describe the epidemic dynamics locally and globally, a coherent framework is missing.

Using a powerful language and methodology borrowed from high energy physics, Professor Sannino and his colleague Giacomo Cacciapaglia from University of Lyon, can now study and forecast the spreading dynamics and containment across different regions of the world.
