Mathematical analysis of a Chlamydia epidemic model with pulse vaccination strategy.

ABSTRACT

In this paper, we have considered a dynamical model of Chlamydia disease with varying total population size, bilinear incidence rate and pulse vaccination strategy. We have defined two positive numbers R0 and (R1≤ R0). It is proved that there exists an infection-free periodic solution which is globally attractive if R0 < 1 and the disease is permanent if R1> 1 The important mathematical findings for the dynamical behaviour of the Chlamydia disease model are also numerically verified using MATLAB. Finally epidemiological implications of our analytical findings are addressed critically.
