The term "slow viruses" is often used to describe which group?

Explanation:
Long incubation periods in certain neurodegenerative diseases led researchers to describe them as slow viruses. The actual infectious agents behind these conditions are prions, which are misfolded proteins that lack nucleic acids. Because they don’t contain DNA or RNA, they aren’t viruses in the conventional sense. Fungi are entirely different organisms, not infectious particles like prions. Prions propagate by converting normal prion protein into the misfolded form, leading to progressive brain damage and very gradual onset. Their resistance to typical sterilization methods also reflects how distinct they are from standard viral pathogens. So, the label “slow viruses” is historical, but the best-fitting group for these agents is prions.
