To describe the spread of COVID‐19, we develop a simple susceptible‐vaccinated‐
infectious‐recovery (SVIR) model. The transmission rate in this model incorporates the …

In addressing the global challenges posed by COVID-19, this study introduces a
mathematical model aimed at investigating the transmission dynamics of COVID-19 and …

COVID-19 has caused substantial morbidity and mortality worldwide. Previous models of
strain 1 vaccination with re-infection when vaccinated, as well as infection with strain 2 did …

This study introduces an SIRS compartmental mathematical model encompassing
vaccination and variable immunity periods for infectious diseases. I derive a basic …

Stay-at-home orders were introduced in many countries during the COVID-19 pandemic,
limiting the time people spent outside their home and the attendance of gatherings. In this …

The Covid-19 virus group is one of the most groups of viruses that influenced the life of
mankind in the past twenty years. A review of previous models was presented. In this work …

We present a simple SVIR (susceptible, vaccinated, infected, recovered) model to analyze
the spread of COVID‐19, incorporating the influence of the population's caution on the …

This study aims at exploring a general and adaptive control strategy to confront the rapid
evolution of an emerging infectious disease ('Disease X'), drawing lessons from the …

Malaria and leptospirosis are emerging vector-borne diseases that pose significant global
health problems in tropical and subtropical regions. This study aimed to develop and …

Brucellosis is a zoonotic disease that poses a huge economic burden to China's livestock
industry. ASEI 1 I 2 RV dynamics model of brucellosis with nonlinear incidence is proposed …
