Modeling the impact of global tuberculosis control strategies.

BCG vaccine and pulmonary tuberculosis

Tuberculosis (TB) is one of the most important public health problems in the world and has been declared as a global emergency by the World Health Organization (WHO) in 1993. Bacillus Calmette-Guérin (BCG) is one of the first developed vaccines to prevent TB. Unfortunately, BCG vaccine has had a limited duration of protection and has shown controversial and variable levels of efficacy, especial...

Evaluation of Active Case Finding (ACF) of Tuberculosis in Slums Population in North of Iran

Background At present of the limitation of the current case finding strategies and the global urgency to improve tuberculosis (TB) case finding, a renewed interest in active case finding (ACF) has risen. World Health Organization (WHO) calls for research on TB screening among low-income countries because of the limitation of the passive case finding strategies. We aimed to evaluated Active Case...

Global properties of a tuberculosis model with lost sight and multi-compartment of latents

A  tuberculosis (TB) model with  lost sight  and multiple latent classes  is considered and studied. We derive the basic reproduction ratio $mathcal R_0$. There is always a globally asymptotically stable equilibrium state. Depending on the value of   $mathcal{R}_0$, this state can be either endemic ($mathcal{R}_0> 1$), or infection-free ($mathcal{R}_0leq 1$). The global asymptotic stability of ...

Management Strategies to Control the COVID-19 Crisis in Masih Daneshvari Hospital, Tehran, Iran

Cost-effectiveness of tuberculosis control strategies among immigrants and refugees.

Today, in Western Europe, Canada and the USA, more than half of all new active tuberculosis (TB) cases occur among foreign-born migrants. This article examines the impact of migration from high TB-incidence to low TB-incidence countries, and compares the cost-effectiveness of different TB control strategies. A Medline search was conducted to identify relevant English language publications prior...
