Abstract :
Chancroid is a highly infectious and curable
sexually transmitted disease caused by the bacterium Haemophilus
Ducreyl (also known as H. Ducreyl). A deterministic mathematical
model for investi- gating the role of treatment on controlling
chancroid epidemic is formulated and rigorously analyzed. A
threshold quantity known as the reproductive number, which measures
the number of secondary infections produced by a single chancroid
infective when introduced in a population of susceptibles in the
presence of treatment has been derived. Equilibria for the model are
determined and their stability are examined. Latin hypercube
sampling has been used to perform the sensitivity analysis of the
reproductive number.
