ABSTRACT

In this research work, Mathematical Model for Measles Transmission Dynamics in Luweero

District of Uganda, SVEIR model was developed and analyzed. The model consists of five non

liner ordinary differential equations. The effective reproductive number, (the number of

secondary infections when a single effective individual is introduced into a population where a

proportion is protected) was obtained. Further the disease free and endemic equilibrium where

obtained and analyzed for stability. Numerical simulation of the various state variables where

obtained using mat lab software. And it shows that the vaccination is capable of reducing the

number of susceptible when the coverage is high.
