Control Strategies for Nipah Virus

摘要

Recently Nipah virus (NiV) appeared in coastal area of Kerala. This virus attacks both animals and human populations through the fruits bats of Pteropodidae Family. It is transmitted from bats to human, bats to bats and human to human. To study the dynamics of NiV, two layered compartmental model is formulated. The two compartments considered here are that of bat and human. Model is constructed using non-linear ordinary differential equations for both the layers. Stability analysis has been carried out at NiV free, bat infectious free and endemic equilibrium point. The model advocates controls as preventive measures in terms of buried, infected bats and dead bodies of human, spraying insecticides on infected bats and in time hospitalization for infected human. Numerical simulation is carried out to study impact of control on respective compartments. Sensitivity analysis is carried out to sort out factors responsible for spread of disease.
