Mathematical models that quantify the dynamics of infectious diseases are crucial predictive tools for the control of ongoing and future outbreaks. In an article publishing on Feb. 19 in the SIAM Journal on Applied Mathematics, a publication of the Society for Industrial and Applied Mathematics, Toshikazu Kuniya studies the global behavior of a multi-group SIR epidemic model with age structure and uses the model to estimate the basic reproduction number for Japan's chlamydia outbreak.
