The species of birds affected, and the species of birds kept at each of the premises have not yet been reported.

Newcastle Disease is a serious notifiable disease of poultry which can cause large losses in unvaccinated domestic poultry, particularly chickens.

It is considered endemic in many countries in Central and South America, Asia, the Middle East and Africa and is occasionally reported in Europe most often in backyard systems in the east.

The causative agent, avian avulavirus type -1 (formerly Avian Paramyxovirus-1) is highly variable in its ability to infect different avian species and to cause differing severity of disease.
