Lyapunov Functions In Epidemiological Modeling

Abstract In this mini thesis, we study the application of Lyapunov functions in epidemiological modeling. The aim is to give an extensive discussion of Lyapunov functions, and use some specific classes of epidemiological models to demonstrate the construction of Lyapunov functions. The study begins with a review of Lyapunov functions in general, and their usage in global stability analysis. Lyapunov’s “direct method” is used to analyse the stability of the disease-free equilibrium. More...

Determinants Of All-Cause Maternal Mortality In Ghana: A Multivariate Decomposition Analysis Of 2007 And 2017 Ghana Maternal Health Surveys

ABSTRACT Background Maternal mortality has seen a significant decline in Ghana over last decade. Stakeholders and government continue to invest in strategic policies aimed to further decrease the ratio of maternal mortality. To achieve the desired results, interventions must be tailored toward specific factors in order to further strengthen the remedy to this health menace. Even though, there has been a decline over the years, international target and standards yet to be achieved. Method Ana...

Entomological Assessment Of Lymphatic Filariasis Transmission In Selected Communities In Ghana

ABSTRACT The resurgence of lymphatic filariasis (LF) infection after several rounds of Mass Drug Administration (MDA) has been the main reason behind constant monitoring of treatment. The MDA is designed to interrupt transmission by reducing microfilaraemia in a community to a threshold that local vectors may not be able to pick up microfilariae (MF) during a blood meal. The current study has been carried out to determine whether transmission had actually been interrupted following stoppage o...
