Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

Online First articles are published online here, before they appear in a journal issue. Online First articles are fully citeable, complete with a DOI. They can be cited, read, and downloaded. Online First articles are published as Open Access (OA) articles to make the latest research available as early as possible.

Open AccessArticles marked with this Open Access icon are Online First articles. They are freely available and openly accessible to all without any restriction except the ones stated in their respective CC licenses.

  • An SEIR epidemic models global analysis that incorporates the bi-linear incidence rate with treatment function   Order a copy of this article

    Abstract: In this paper, the bi-linear incidence rate and saturated treatment function of the SEIR epidemic model are examined, with a particular emphasis on the impact of inadequate treatment on the infectious diseases transmissibility. The basic reproductive number, which determines the potential for disease extinction or persistence, is evaluated. The determination of threshold requirements for all types of equilibrium points is examined. We prove that the equilibrium is locally asymptotically stable by calculating the eigenvalues and using the Routh-Hurwitz criterion. The autonomous convergence theorem and the Lyapunov function are also used to investigate the disease-free and endemic equilibriums global asymptotical stability. The research carried out suggested that the commencement of treatment is a highly relevant element in infection control. The results of the numerical simulations are used to support and verify the theoretical findings.
    Keywords: mathematical models; epidemiology; treatment; basic reproduction number; stability analysis.
