Infectious diseases are a threat to human health and a hindrance to societal development.
Consequently, the spread of diseases in both time and space has been widely studied …

In this article, a fractal-fractional order tuberculosis mathematical model is presented for the
existence results, numerical simulations and stability analysis. The model has six classes S …

Brucellosis, the most common zoonotic disease worldwide, represents a great threat to
animal husbandry with the potential to cause enormous economic losses. Meanwhile …

In this work, a swarming computational procedure is presented for the numerical treatment of
the dynamical model of the susceptible, exposed, infected, and recovered (SEIR) classes …

A worldwide multi-scale interplay among a plethora of factors, ranging from micro-pathogens
and individual or population interactions to macro-scale environmental, socio-economic and …

In this paper, we present and analyze an SEIR Zika epidemic model. Firstly, we investigate
the model with constant controls. The steady states of the model is found to be locally and …

Since December 2019, an outbreak of a novel coronavirus pneumonia (WHO named COVID-
19) swept across China. In Shanxi Province, the cumulative confirmed cases finally reached …

The transmission of infectious diseases has been studied by mathematical methods since
1760s, among which SIR model shows its advantage in its epidemiological description of …

In this paper, a noninteger order Brucellosis model is developed by employing the Caputo–
Fabrizio noninteger order operator. The approach of noninteger order calculus is quite new …

Tuberculosis (TB), an air-borne infectious disease, is a major public-health problem in
China. The reported number of the active tuberculosis cases is about one million each year …
