This article examines hepatitis B dynamics under distinct infection phases and multiple
transmissions. We formulate the epidemic problem based on the characteristics of the …

Salmonella Typhi, a bacteria, is responsible for typhoid fever, a potentially dangerous
infection. Typhoid fever affects a large number of people each year, estimated to be between …

Coronavirus 2019 (COVID-19) is the current global buzzword, putting the world at risk. The
pandemic's exponential expansion of infected COVID-19 patients has challenged the …

The terms susceptibility, exposure, infectiousness, and recovered all have some inherent
ambiguity because different population members have different susceptibility levels …

Typically, a computer has infectivity as soon as it is infected. It is a reality that no antivirus
programming can identify and eliminate all kinds of viruses, suggesting that infections would …

A susceptible, exposed, infectious, quarantined and recovered (SEIQR) model with fuzzy
parameters is studied in this work. Fuzziness in the model arises due to the different degrees …

In this article, a Susceptible-Exposed-Infectious-Recovered (SEIR) epidemic model is
considered. The equilibrium analysis and reproduction number are studied. The …

This work investigates the computational study of a six-compartmental mathematical model
of tuberculosis disease dynamics with the impact of vaccination. Traditional mathematical …

The application of fuzzy theory is vital in all scientific disciplines. The construction of
mathematical models with fuzziness is little studied in the literature. With this in mind and for …

Rubella is an infectious disease that can spread globally. It spreads in the subtropics as well
as the tropics. Although it is commonly thought to be a non-fatal condition, there are several …
