Linkages between disease in humans and the maladies of animals continue to be a focus for those concerned with disease effects on human health. References to animal diseases, particularly zoonoses such as rabies and glanders, are found in the writings of Greek (Hippocrates, Democritus, Aristotle, Galen, Dioscorides), Byzantine (Oribasius, Actius of Amida), and Roman (Pliny the Elder, Celsus) physicians and naturalists. Also, early advances in disease knowledge were closely associated with the study of contagions in animals to the extent that “The most complete ancient accounts of the concepts of contagion and contamination are found in treatises on veterinary medicine.”
Opportunities for disease transfer between animals and humans have increased during modern times, partly because of advances in animal husbandry and intensive agriculture that result in increased contacts among humans, domestic animals, and wildlife. Infectious pathogens exploit these contacts, and must be considered in this era of increased world tensions and international terrorism.
