Spatial model results of viral infection in a two-dimensional, epithelial sheet. Results shown for 1% (top), 5% (middle), and 10% (bottom) initially infected cells at 0, 3, 4, 5, 7, and 14 days in simulation time. Epithelial cells shown as blue when susceptible, green when infected, red when virus-releasing, and black when dead. Lower-right color bar shows levels in the virus field, from blue (0) to red (0.2)
