Since its discovery 20 years ago, Newcastle disease has been recognized in at least 16 countries throughout the world. The first reports of its occurrence came from the Dutch East Indies in 1926 followed shortly by an outbreak at Newcastle on the Tyne, England, from which the disease derived its current name. A disease present among chickens in California for the past decade and known by such names as a "respiratory nervous disorder" and "avian pneumoencephalitis" was not recognized as Newcastle disease until 1944.
