This paper investigates a fractional derivative model of Chlamydia-Gonorrhea co-infection
using Caputo derivative definition. The positivity boundedness of the model is established …

The rise of drug resistance has become a major obstacle in treating tuberculosis (TB),
significantly contributing to the increasing disease burden. Therefore, it is essential to study …

One of the realities of the COVID-19 worldwide pandemic is the occurrence of infected
individuals with COVID-19 and two other diseases, Monkeypox and HIV. This study presents …

Abstract Rat-Bite Fever is a zoonotic transmitted bacterial disease caused by either
Streptobacillus moniliformis or Spirillum minus. The disease is fatal and has high profile of …

This research introduces a sophisticated mathematical model for understanding the
transmission dynamics of COVID-19, incorporating both integer and fractional derivatives …

The COVID-19 pandemic has undergone significant changes due to the emergence of new
variants. The Delta and Omicron variants, in particular, have posed unique challenges …

Leptospirosis poses a significant public health challenge, with a growing incidence in both
human and animal populations. The complex interplay between reservoir hosts …

This study explores a mathematical model in continuous time, elucidating the transmission
dynamics of the co-infection of COVID-19 and Monkeypox. We implemented an optimal …

Abstract The World Health Organization has disclosed that the hybrid-immune and
immunodeficient individuals are two distinct classes of individuals susceptible to the COVID …

Coronavirus infection is a disease that causes death and threatens human life; for
prevention, it is necessary to quarantine susceptible, exposed, and infected populations and …
