The long-term dynamics of the populations in each compartment predicted by the base model, which converges to an endemic steady state after approximately 20 years. The larval tick population of 115,000 does not change over time, but each of the other populations do. The susceptible compartments for the nymphs, adults, mice, and deer decrease to 8322, 1352, 32, and 0.18, respectively. The infected compartments for the nymphs, adults, mice, and deer increase to 4678, 1948, 18, and 0.07, respectively.
