  A deterministic mathematical model is formulated and analyzed to study the
transmission dynamics of Nipah virus both qualitatively and numerically.
Existence and stability of equilibria were investigated and the model was
rigorously analyzed. We then incorporated time dependent controls on the model,
using Pontryagin's Maximum Principle to derive necessary conditions for the
optimal control of the disease. We examined various combination strategies so
as to investigate the impact of the controls on the spread of the disease.
Through the numerical results, we found out that the optimal control strategies
help to reduce the burden of the diseases significantly
