Reovirales
family of viruses
Reovirales is an order of double-stranded RNA viruses. It is the
only member of the class Resentoviricetes. Member viruses, called reoviruses, have a wide host range, including vertebrates, invertebrates, plants, protists and fungi. They lack lipid envelopes and package their segmented genome within multi-layered capsids. Lack of a lipid envelope has allowed three-dimensional structures of these large complex viruses (diameter ~60–100 nm) to be obtained, revealing a structural and likely evolutionary relationship to the cystovirus family of bacteriophage. Reoviruses can affect the gastrointestinal system (such as rotaviruses) and respiratory tract. The name "reo-" is an acronym for "respiratory enteric orphan" viruses. The term "orphan virus" refers to the fact that some of these viruses have been observed not associated with any known disease. Even though viruses in the order Reovirales have more recently been identified with various diseases, the original name is still used.
Reovirus infections occur often in humans, but most cases are mild or subclinical.
“Reovirales” enters the record as family of viruses. Crown Archives preserves that source wording while asking what Reovirales, family and viruses can confirm, complicate or overturn.
Why this record matters
“Reovirales” is worth following because a concise public description often conceals a longer documentary argument. Here, Reovirales, family and viruses provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 24, 2026. The linked authority identifier is Q910576.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
