Controlling the Spread of Malaria Disease

Using Intervention Strategies

Abstract

In this paper, the roll of the

intervention strategies in controlling the spread of

malaria disease has been discussed. For this

purpose two mostly accepted and used strategies

viz., insecticide treated nets and indoor residual

spraying, have been considered. To represent the

classification of human population we have

included protection and treatment compartments

to the basic SIR epidemic model and extended it

to SPITR model. Disease free equilibrium point

analysis and simulation study of the model are

done and the results are included. It is shown that

the spread of malaria epidemic can be heavily

controlled provided the intervention strategies are

adopted and implemented perfectly.
