In this article, we develop a mathematical model considering susceptible, exposed, infected,
asymptotic, quarantine/isolation and recovered classes as in case of COVID-19 disease …

Mathematical models of HIV-1 infection can help interpret drug treatment experiments and
improve our understanding of the interplay between HIV-1 and the immune system. We …

In this paper, a stochastic and a deterministic SIS epidemic model with isolation and varying
total population size are proposed. For the deterministic model, we establish the threshold R …

Politics is a crucial aspect of society. It has a very high impact on the development of a
community and its population. Thinking and acts of a few political persons/parties affect the …

Abstract The coronavirus disease (COVID-19) brought the world to a halt in March 2020.
Various prediction and risk management approaches are being explored worldwide for …

Background: SARS-CoV-2, the novel coronavirus that causes COVID-19, is a global
pandemic with higher mortality and morbidity than any other virus in the last 100 years …

We investigate an epidemic model of two diseases. The primary disease is assumed to be a
slowly progressing disease, and the density of individuals infected with it is structured by …

In this research work, we present an exciting mathematical analysis of a stochastic model,
using a standard incidence function, for infectious disease hepatitis C transmission …

Background: SARS-CoV-2, the virus that caused the global COVID-19 pandemic, has
severely impacted Central Asia; in spring 2020, high numbers of cases and deaths were …

BACKGROUND: There are many models that study aspects of smoking habits: the influence
of price, tax, relapse time, and the effects of prohibition. There are also studies examining …
