We propose a Caputo-based fractional compartmental model for the dynamics of the novel
COVID-19 pandemic. The newly proposed nonlinear fractional order model is an extension …

Human immunodeficiency virus (HIV) is a life life-threatening and serious infection caused
by a virus that attacks CD 4+ T-cells, which fight against infections and make a person …

Recently, a general framework of fractional operators, that includes the Caputo model as a
particular case, has been introduced and some applications in the area of fractional calculus …

The aim of this work is to present a design of Morlet wavelet neural network (MWNN) for
solving a novel prevention category (P) in the HIV system, known as HIPV mathematical …

In the present paper, we propose and analyze a nonlinear fractional-order SEIR (susceptible-
exposed-infected-recovered) epidemic model to transmit HIV. The fixed points of the model …

In this work, a fractional order hepatitis B virus infection model with both cell-to-cell and virus-
to-cell transmissions and adaptive immunity will be examined. The adaptive immunity that …

In this paper, we establish and analyze a stochastic human immunodeficiency virus model
with both virus-to-cell and cell-to-cell transmissions and Ornstein–Uhlenbeck process, in …

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 …

Serological studies show that besides the development of suitable antibodies that are
evidenced in people who get infected with SARS‐CoV2 or in people who are vaccinated …

In recent times, several infectious diseases that breakthrough contagiousness in vaccinated
people and reinfections in primarily infected counterparts have become more common. In …
