epidemiological models ,reaction-diffusion model, Fisher’s equation,public health policy,


n most recent time worrying epidemic was HIV, Influenza, Tuberculosis etc. While there are many complicating factors, simple mathematical models can provide much insight into the dynamics of disease epidemics and help officials make decisions about public health policy in this subject matter. We shall discuss two of the classical and still much used, deterministic epidemiological models which are responsible for spreading diseases in an area. We shall then consider a reaction-diffusion model, Fisher’s equation, a new integro-differential equation model for the spread of an epidemic in space and to evaluate strategies to control an epidemic.
