  Recent work from public health experts suggests that incorporating human
behavior is crucial in faithfully modeling an epidemic. We present a
reaction-diffusion partial differential equation SIR-type population model for
an epidemic including behavioral concerns. In our model, the disease spreads
via mass action, as is customary in compartmental models. However, drawing from
social contagion theory, we assume that as the disease spreads and prevention
measures are enacted, noncompliance with prevention measures also spreads
throughout the population. We prove global existence of classical solutions of
our model, and then perform R0-type analysis and determine asymptotic behavior
of the model in different parameter regimes. Finally, we simulate the model and
discuss the new facets which distinguish our model from basic SIR-type models.
