Abrupt phase transition of epidemic spreading in simplicial complexes

Epidemic spreading is probably the major concern of human health. Precise epidemic models are needed to further develop actions to prevent and palliate the effects of disease propagation. Here the authors present a mathematical model, that captures de main physics of epidemic spreading beyond pairwise contagions, considering group-contagion. The results pave the way for a deeper understanding on the consequences of complex patterns of contagion.
