Investigation of an outbreak of velogenic viscerotropic Newcastle disease in pet birds in Michigan, Indiana, Illinois, and Texas.
An outbreak of velogenic viscerotropic Newcastle disease in exotic pet birds in the United States from April through July 1991 was investigated. More than 2,000 pet birds in 5 states (Michigan, Indiana, Illinois, Texas, and Maryland) were tested. Infected birds were found in Michigan, Illinois, Indiana, and Texas. This disease was eradicated without spread to domestic poultry. Epidemiologic investigations revealed the source of infection to be double yellow-headed Amazon parrots suspected to be illegally imported into Texas.
