Infectious bursal disease is a highly contagious viral disease which causes significant economic losses due to mortality, reduced performance and immunosuppression, leading to increased susceptibility to other diseases. The virus is resistant to a wide range of temperature and pH. It is rapidly spread by direct contact between birds and can survive for extended periods of time on inanimate objects, contaminated feed, etc.
The disease has a worldwide prevalence, thus it is not entirely controlled. This handbook carries out a complete review in which the authors use graphic resources and short pieces of text to describe the disease in an understandable and simple way. The information provided will permit to the professionals to suitably tackle the disease.
