Study on control of bird flu outbreak within a poultry farm

In a production process of a poultry farm, the entire population of birds is kept constant at the manageable capacity. After intrusion of influenza virus, infected birds remain as a source of infection regardless of being alive or dead, unless they are completely removed. A mathematical model based on these factors is analysed to study time evolution of populations of susceptible birds and infected birds, and concentration of bird flu virus. Numerical results show that the population of domestic birds can be made secure against infection by proper vaccination and proper removal of infected birds.
