Ladib M, Ouhinou A, Yakubu A
Infect Dis Model
. 2024 Feb;
9(2):329-353.
PMID: 38371875
We develop a mathematical model to investigate the effect of contact tracing on containing epidemic outbreaks and slowing down the spread of transmissible diseases. We propose a discrete-time epidemic model...

Bull Math Biol
. 2021 Dec;
84(1):17.
PMID: 34923617
In ecological systems, the hydra effect is an increase in population size caused by an increase in mortality. This seemingly counterintuitive effect has been observed in several populations, including fish,...

. 2021 Nov;
18(6):8374-8391.
PMID: 34814304
The Far North Region of Cameroon, a high risk cholera endemic region, has been experiencing serious and recurrent cholera outbreaks in recent years. Cholera outbreaks in this region are associated...

. 2021 Oct;
15(1):523-562.
PMID: 34672907
In a recent paper, Che et al. [5] used a continuous-time Ordinary Differential Equation (ODE) model with risk structure to study cholera infections in Cameroon. However, the population and the...

Asymptotic behavior of a discrete-time density-dependent SI epidemic model with constant recruitment
KulenoviC M, NurkanoviC M, Yakubu A
J Appl Math Comput
. 2021 Feb;
67(1-2):733-753.
PMID: 33613143
We use the epidemic threshold parameter, , and invariant rectangles to investigate the global asymptotic behavior of solutions of the density-dependent discrete-time SI epidemic model where the variables and represent...

J Biol Dyn
. 2020 Apr;
14(1):308-331.
PMID: 32301682
We use juvenile-adult discrete-time infectious disease models with intrinsically generated demographic population cycles to study the effects of age structure on the persistence or extinction of disease and the basic...

320:108303.
PMID: 31857092
Since 1991, Cameroon, a cholera endemic African country, has been experiencing large cholera outbreaks and cholera related deaths. In this paper, we use a "fitted" demographic equation (disease-free equation) to...
