Significance of antiviral therapy and CTL-mediated immune response in containing hepatitis B and C virus infection.
(Elsevier B. V., 2021-01-12)
Viral infections remain a major cause of deaths globally. Here, we focus on Hepatitis B and C viruses (HBV and HCV) infection dynamics in the liver and blood cells, taking into account non-cytotoxic and cytotoxic mediated ...
Modelling the Control of the Impact of Fall Armyworm (Spodoptera frugiperda) Infestations on Maize Production.
(Hindawi, 2021-03-18)
In this paper, we propose and analyse a stage-structured mathematical model for modelling the control of the impact of Fall Armyworm infestations on maize production. Preliminary analysis of the model in the vegetative and ...
Dynamical and optimal control analysis of a seasonal Trypanosoma brucei rhodesiense model.
(AIMS Press, 2020-02-27)
The effects of seasonal variations on the epidemiology of Trypanosoma brucei rhodesiense disease is well documented. In particular, seasonal variations alter vector development rates and behaviour, thereby influencing the ...
A vaccination model for COVID-19 in Gauteng, South Africa
(KeAi Communications Co., 2022-09)
The COVID-19 pandemic provides an opportunity to explore the impact of government mandates on movement restrictions and non-pharmaceutical interventions on a novel infection, and we investigate these strategies in early-stage ...
A Mathematical Model of Contact Tracing during the 2014–2016 West African Ebola Outbreak.
(MDPI Open Access Journals, 2021-03-12)
The 2014–2016 West African outbreak of Ebola Virus Disease (EVD) was the largest and most deadly to date. Contact tracing, following up those who may have been infected through contact with an infected individual to prevent ...
A fractional-order Trypanosoma brucei rhodesiense model with vector saturation and temperature dependent parameters.
(Springer Open, 2020-06-11)
Temperature is one of the integral environmental drivers that strongly affect the distribution and density of tsetse fly population. Precisely, ectotherm performance measures, such as development rate, survival probability ...
Modeling the Effect of HIV/AIDS Stigma on HIV Infection Dynamics in Kenya.
(Springer Link, 2021-04-05)
Stigma toward people living with HIV/AIDS (PLWHA) has impeded the response to the disease across the world. Widespread stigma leads to poor adherence of pre- ventative measures while also causing PLWHA to avoid testing and ...
Mathematical modeling of the dynamics of health risks associated with alcoholism in Tanzania: a literature review.
(SCIK Publishing Corporation, 2020-07-13)
In this paper, a number of alcohol related studies have been reviewed in light of the strength and challenges of the models developed for their applicability in Tanzanian drinking context. The aim of this paper is to provide ...
Dynamics for a non-autonomous fall armyworm-maize interaction model with a saturation functional response
(AIMS Press, 2021-11-09)
In this study, we present a non-autonomous model with a Holling type II functional response, to study the complex dynamics for fall armyworm-maize biomass interacting in a periodic environment. Understanding how seasonal ...
A fractional-order fall armyworm-maize biomass model with naturally beneficial insects and optimal farming awareness.
(Elsevier, 2021-11-01)
Maize remains an important food crop in Africa. However, the production of this crop, and consequently the livelihood of the growers are threatened by the invasion and widespread infestation of the fall armyworm which ...
