Biomathematics has become one of the most significant areas of research as a result of
interdisciplinary study. Chronic diseases sometimes referred to as non-communicable and …

In recent years, COVID-19 has evolved into many variants, posing new challenges for
disease control and prevention. The Omicron variant, in particular, has been found to be …

Despite the existence of a secure and reliable immunization, measles, also known as
rubeola, continues to be a leading cause of fatalities globally, especially in underdeveloped …

In this work, we replaced the integer derivative with Caputo derivative to model the
transmission dynamics of measles in an epidemic situation. We began by recalling some …

In this paper, the ABC fractional derivative is used to provide a mathematical model for the
dynamic systems of substance addiction. The basic reproduction number is investigated, as …

In this work, we examine the impact of certain preventive measures for effective measles
control. To do this, a mathematical model for the dynamics of measles transmission is …

In this paper, a Caputo fractional order HBV humoral and CTL immunity model with more
general mass action incidences is established, the existence and uniqueness of positive …

This study employs a mathematical model to analyze and forecast the severe outbreak of
SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), focusing on the socio …

Parameter identification plays a crucial role in the study of dynamics for fractional order
structural models. This article introduces an innovative approach to identify parameters by …

Young children frequently die from measles, which is a major global health concern. Despite
being more prevalent in infants, pregnant women, and people with compromised immune …
