We investigate the effect of heterogeneous environment on the spread of disease in systems of active agents. Here we couple susceptible-infected-recovered (S-I-R) contagion dynamics to a system of self-propelled active particles with polar alignment, in the presence of randomly distributed obstacles. The heterogeneity of the environment is controlled by the density of obstacles. The temporal-spatial dynamics of the system is determined by the alignment strength and Peclet number as well as the density of the obstacles. We analyze how the heterogeneity of the environment results in rich set of spatial structures which significantly affect the epidemic dynamics of the disease. We further show that increasing the heterogeneity of the environment could change the outbreaks statistics in a non-monotonic way.
