Abstract
A brief presentation is given of the enteric viral infections of young animals. The general characteristics of rotaviruses, coronaviruses and parvoviruses are reported, and the different aspects of the diseases associated with these viruses are discussed. Certain suggestions are made regarding the prevention of these diseases.
Keywords: Viral diarrhea, rotaviruses, coronaviruses, parvoviruses
