Abstract
In this work we present an agent-based computational model to study the
spreading of the tuberculosis (TB) disease on age-structured
populations. The model proposed is a merge of two previous models: an
agent-based computational model for the spreading of tuberculosis and a
bit-string model for biological aging. The combination of TB with the
population aging, reproduces the coexistence of health states, as seen
in real populations. In addition, the universal exponential behavior of
mortalities curves is still preserved. Finally, the population
distribution as function of age shows the prevalence of TB mostly in
elders, for high efficacy treatments. (C) 2015 Elsevier B.V. All rights
