Control and elimination in an SEIR model for the disease dynamics of Covid-19 with vaccination
Witbooi, Peter Joseph; Vyambwera, Sibaliwe Maku; Nsuami, Mozart Umba (AIMS Press, 2023)COVID-19 has become a serious pandemic affecting many countries around the world since it was discovered in 2019. In this research, we present a compartmental model in ordinary differential equations for COVID-19 with ... -
Mathematical analysis of TB model with vaccination and saturated incidence rate
Witbooi, Peter Joseph; Mengistu, Ashenafi Kelemu (Hindawi, 2020)The model system of ordinary differential equations considers two classes of latently infected individuals, with different risk of becoming infectious. The system has positive solutions. By constructing a Lyapunov function, ... -
Stochastic modeling of a mosquito-borne disease
Abiodun, Gbenga J.; Witbooi, Peter Joseph; van Schalkwyk, Garth J. (Springer Nature, 2020)We present and analyze a stochastic differential equation (SDE) model for the population dynamics of a mosquito-borne infectious disease. We prove the solutions to be almost surely positive and global. We introduce a ...
