The Role of Treatment on Controlling Chancroid Prevalence

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.
