MATHEMATICAL MODELLING OF THE IMPACT OF REDUCED INFECTION ON LASSA HAEMORRHAGIC FEVER TRANSMISSION DYNAMICS: A THEORETICAL STUDY
Abstract
A novel deterministic model for the transmission dynamics of Lassa Haemorrhagic Fever (LHF) is designed and deployed to qualitatively assess the role of the impact of reduced relative infection of the human-human mode of transmission compared to the rodent-human mode of transmission on the population population dynamics for Lassa Haemorrhagic Fever disease burden. The model is shown to undergo the backward bifurcation phenomenon due to the presence of the parameter which accounts for the rate at which temporary immunity wanes. A unique threshold for the rate at which temporary
immunity wanes was also obtained. A special case of the model showed that the disease-
free equilibrium was globally asymptotically
