In this work, a vaccination model for Chlamydia trachomatis with cost-effectiveness optimal
control analysis is developed and analyzed. The disease free equilibrium of model is shown …

Typhoid fever is a contagious disease that is generally caused by bacteria known as
Salmonella typhi. This disease spreads through manure contamination of food or water and …

In this study, we develop and analyze a mathematical model of hookworm transmission
dynamics with two different classes of infection and different stages of parasite …

In this study, we used a deterministic mathematical model to investigate the dynamics of
typhoid disease in a community. Different control strategies were used to determine efficient …

Unemployment is one of the major vices in our contemporal society, which weigh greatly on
the economy of such nation. It is also, a fact that knowing ones enemy before battle gives 50 …

The optimal control of pneumonia disease is very important in the management of the
disease within a given population. Pneumonia is one of the leading causes of death …

This paper presents and studies a deterministic mathematical model of typhoid fever
dynamics. We verified the uniqueness and the existence of the model's equations using the …

In this paper, a six compartmental model for typhoid transmission dynamics incorporating
vaccination as a controlling measure in human population was formulated. Mathematical …
