In this paper, we have proposed and analyzed a predator–prey system introducing the cost
of predation fear into the prey reproduction with Holling type-II functional response in the …

Influenza diseases cause tremendous damage to global public health and economics. The
modelling of the spread of influenza has been extensively done, but the population level …

In this work, we analyze a degenerate heteroclinic cycle that appears in a Lorenz-like
system when one of the involved equilibria changes from real saddle to saddle-focus. First …

In this manuscript, we formulate a malaria model with nonlinear incidence and recovery
rates to study the impact of the health system's available resources on disease spread and …

This study investigates a symmetric fractional-order epidemic model with time delays and
non-monotonic incidence rates, considering two viral strains. By confirming the existence …

Zika is a mosquito-transmitted viral disease which may spread directly by the vector or
sexual transmission. Zika virus may persist in semen and urine for a long time after …

The basic reproduction, or reproductive number, is a useful index that indicates whether or
not there will be an epidemic. However, it is also very important to determine whether an …

This investigation aims to enhance and broaden the mathematical model that governs a
dynamic stochastic SEIRS (Susceptible, Exposed, Infective, and Recovery) epidemic. This …

In this work, we analyze a degenerate heteroclinic cycle that appears in a Lorenz-like
system when one of the involved equilibria changes from real saddle to saddle-focus. First …

Real-time forecasting of infectious diseases is crucial for effective public health
management, particularly during outbreaks. When infectious disease predictions are based …
