Tuberculosis and COVID-19 are among the diseases with major global public health
concern and great socio-economic impact. Co-infection of these two diseases is inevitable …

The SIRS model with constant vaccination and immunity waning rates is well known to show
a transition from a disease-free to an endemic equilibrium as the basic reproduction number …

A co-infection with Covid-19 and dengue fever has had worse outcomes due to high
mortality rates and longer stays either in isolation or at hospitals. This poses a great threat to …

A mathematical model is a beautiful and powerful way to depict the condition of
epidemiological disease transmission. In this work, we used a nonlinear differential equation …

This study developed a deterministic transmission model for the coronavirus disease of
2019 (COVID-19), considering various factors such as vaccination, awareness, quarantine …

In this manuscript, we develop a fractional-order mathematical model to characterize the
propagation dynamics of COVID-19 outbreaks and assess the influence of vaccination …

In this research, we developed model of SIR for COVID-19 spread. The model is
represented by a deterministic discrete-time model. The model is constructed with divided …

In this research paper the identification and large implementation of a powerful SARS-CoV-2
vaccine may prevent considerable illnesses and fatalities from COVID-19 while minimizing …

In this paper, we develop a mathematical model for the spread of COVID-19 outbreak, taking
into account vaccination in susceptible and recovered populations. The model divides the …

This study analyzes the Susceptibles Infected Recovered Death (SIRD) epidemic model of
COVID-19 transmission by considering vaccination in Indonesia. The SIRD epidemic …
