Banna virus
species of virus
Banna virus (BAV) is a virus belonging to Reovirales, an order of segmented, non-enveloped, double-stranded RNA viruses. It is an arbovirus, being primarily transmitted to humans from the bite of infected mosquitoes of the genus Culex. Pigs and cattle have also been shown to become infected. The most common symptom of infection is fever, but in some cases encephalitis may occur. There is no specific treatment for infection, so treatment is aimed at alleviating the severity of symptoms until the immune system has cleared the infection.
Virology
Structure and genome
BAV is a small (72–75 nm in size), non-enveloped, double-stranded RNA virus surrounded by an icosahedral protein coat. Fibre proteins extend outward from the surface of the protein coat. The genome of BAV is about 19,500 base pairs in length, linear and segmented into 12 parts, encoding for genes VP1-12. Seven of these, VP1-4 and VP8-10, are structural proteins. VP4 and VP9 form the outer protein coat.
Begin with the source’s own compact description: “Banna virus” is species of virus. The dossier treats that line as a proposition to test through Banna, virus and species, not as a finished interpretation.
Why this record matters
The phrase “species of virus” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 26, 2025. The linked authority identifier is Q16243472. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
