Prions differ from viruses as prions do not include any nucleic acids. Generally, prions are smaller than viruses and can only be seen through electron microscope when they have aggregated and formed a cluster.
Viruses and bacteria are microorganisms that contain genetic material and they do not generate spontaneously. Prion disease is caused by a change in shape of a cellular protein and the resulting pathogenic prion proteins begin to recruit and change normal proteins into abnormal shape.
Infectious agents, prions were originally believed to be anomalous viruses, hence their inclusion here. They consist of only protein with no enclosed nucleic acid.
