Direct and indirect transmission of typhoid fever model with optimal control

Mathematical Model for Transmission Dynamics of Hepatitus C Virus with Optimal Control Strategies

An epidemic model with optimal control strategies was investigated for Hepatitus C Viral disease that can be transmitted through infected individuals. In this study, we used a deterministic compartmental model for assessing the effect of different optimal control strategies for controlling the spread of Hepatitus C disease in the community. Stability theory of differential equations is us...

Modelling and Optimal Control of Typhoid Fever Disease with Cost-Effective Strategies

We propose and analyze a compartmental nonlinear deterministic mathematical model for the typhoid fever outbreak and optimal control strategies in a community with varying population. The model is studied qualitatively using stability theory of differential equations and the basic reproductive number that represents the epidemic indicator is obtained from the largest eigenvalue of the next-gene...

HEMOPHAGOCYTIC SYNDROME IN TYPHOID FEVER AND BRUCELLOSIS

Hemophagocytic syndrome is a non-malignant process that is characterized clinically by fever, hepatomegaly, splenomegaly, pancytopenia in peripheral blood, and reactive histiocytes in the bone marrow. Bacterial infectious diseases like typhoid fever and brucellosis and viral infections including CMV, herpes viruses, and Epstein-Barr virus are diagnosed as the cause of this syndrome. In thi...

A model for ovine brucellosis incorporating direct and indirect transmission.

In this work, we construct and analyse an ovine brucellosis mathematical model. In this model, the population is divided into susceptible and infected subclasses. Susceptible individuals can contract the disease in two ways: (i) direct mode - caused by contact with infected individuals; (ii) indirect mode - related to the presence of virulent organisms in the environment. We derive a net reprod...
