Query: Contagion dynamics in self-organized systems of self-propelled agents   We investigate the Susceptible-Infectious-Recovered contagion dynamics in a
system of self-propelled particles with polar alignment. Using agent-based
simulations, we analyze the outbreak process for different combinations of the
spatial parameters (alignment strength and Peclet number) and epidemic
parameters (infection-lifetime transmissibility and duration of the individual
infectious period). We show that the emerging spatial features strongly affect
the contagion process. The ordered homogeneous states greatly disfavor
infection spreading, due to their limited mixing, only achieving large
outbreaks for high values of the individual infectious duration. The disordered
homogeneous states also present low contagion capabilities, requiring
relatively high values of both epidemic parameters to reach significant
spreading. Instead, the inhomogeneous ordered states display high outbreak
levels for a broad range of parameters. The formation of bands and clusters in
these states favor infection propagation through a combination of processes
that develop inside and outside of these structures. Our results highlight the
importance of self-organized spatiotemporal features in a variety of contagion
processes that can describe epidemics or other propagation dynamics, thus
suggesting new approaches for understanding, predicting, and controlling their
spreading in a variety of self-organized biological systems, ranging from
bacterial swarms to animal groups and human crowds.
