Gumboro disease was first described in the 1960’s in Gumboro, Delaware, USA. Many scientific authors also refer to it as Infectious Bursal Disease (IBD) as the virus invades and replicates in the Bursa of Fabricius.

Soon after the first discovery of Gumboro disease it became clear that biosecurity and cleaning and disinfection
were not sufficient to control the disease, and vaccines were quickly developed and widely used.
These vaccines proved to be efficacious as the clinical signs of the disease disappeared.
Over the last 50 years the economic development in many countries has increased the number of birds placed per farm and had led to stricter biosecurity and surveillance programs.
Gumboro disease, despite the wide use of vaccines and increased biosecurity, is however still very much present and ranks among the top five diseases in almost all countries globally.
One of the reasons for this dominance is that the Gumboro disease virus is a very persistent virus surviving in poultry houses in the absence of chickens during downtime periods.
