Parameterization and Forecasting of Childhood Pneumonia Model Using Least Square Approximation, Lagrange Polynomial and Monte Carlo Simulation

Cyrus Gitonga Ngari & Dominic Makaa Kitavi · Annual Research & Review in Biology · 2020

Despite a study by [1] proposing a simple model of under five years pneumonia, doubt lingers regarding its reliability, sufficiency and validity. The research question is whether the model is valid for use or not?  The objectives of this study were to: incorporate exit rate from...

Modelling Vaccination and Treatment of Childhood Pneumonia and Their Implications

Cyrus Gitonga Ngari · Journal of Advances in Mathematics and Computer Science · 2018

This paper presents a deterministic model for pneumonia transmission and uses the model to assess the potential impact of the vaccination, treatment and efficacy of vaccination drugs in lowering the public health impact of the pneumonia disease. The model is based on the Suscepti...
