[1] In July 2013, the species and the genus cuevavirus were ratified by the International Committee on Taxonomy of Viruses (ICTV) to be included in its report, therefore the name is now to be italicized.

[1][2] According to the rules for taxon naming established by the International Committee on Taxonomy of Viruses (ICTV), the name Lloviu virus is always to be capitalized (because "Lloviu" is a proper noun), but is never italicized, and may be abbreviated (with LLOV being the official abbreviation).

[citation needed] LLOV was discovered in 2011 in Schreibers's long-fingered bats (species Miniopterus schreibersii) that were found dead in Cueva del Lloviu in 2002, Asturias, Spain, as well as in caves in Spanish Cantabria and in caves in France and Portugal.

Necropsies of dead bats did not reveal macroscopic pathology, but microscopic examination suggested viral pneumonia.

[6] Updated genome data was obtained from the Hungarian samples in 2020, using the Nanopore sequencing technique.

At the center would be the helical ribonucleocapsid, which would consist of the genomic RNA wrapped around a polymer of nucleoproteins (NP).

[11] The virus RdRp would partially uncoat the nucleocapsid and transcribe the genes into positive-stranded mRNAs, which would then be translated into structural and nonstructural proteins.

The most abundant protein produced would be the nucleoprotein, whose concentration in the cell would determine when L switches from gene transcription to genome replication.

Replication would result in full-length, positive-stranded antigenomes that would in turn be transcribed into negative-stranded virus progeny genome copies.

Newly synthesized structural proteins and genomes would self-assemble and accumulate near the inside of the cell membrane.
