Table IV.

Predicted size (number of deer herds infected) of an outbreak of foot and mouth disease in a population of white-tailed deer in an area of South Texas for each season by ecoregion (Edwards Plateau and South Texas brush). Results shown are from 100 simulations of a susceptible-latent-infectious-resistant geographic automata model (Sirca) for each seasonal deer distribution.
