Model details.  (A) Coordinate system and x-direction limits for the models.  (B) Position-dependent infection rates and recovery rates, showing the two different scaling parameters used.  (C) Disease-dependent personal location preference, showing arrows for direction of movement bias.  (D)  [update figure to just use two zones, outer as r_s] Illustration of the zonal model used for the 2D simulations, showing the repulsion zone (within \(r_r\)), alignment zone (between \(r_r\) and \(r_o\)), the attraction zone (between \(r_o\) and \(r_a\)), and the angle defining the blind spot (\(\theta_B\)).
