The story of the word

Rudolf Virchow built the word in the nineteenth century while pressing his argument that human and veterinary medicine are one field with one set of problems. Rabies, plague, brucellosis and most new influenzas are zoonoses. Nosos is the word Homer uses in the first book of the Iliad for the plague Apollo shoots into the Greek camp, which arrives, as it happens, by way of animals.
