Ruhugu virus
Ruhugu virus, scientific name Rubivirus ruteetense, is a species of virus in the genus Rubivirus. It was discovered in 2019 in healthy Ugandan bats. It belongs to the family of Matonaviridae, a single-stranded RNA of positive polarity which is enclosed by an icosahedral capsid.

Discovery and habitat
Ruhugu virus was discovered in healthy Cyclops roundleaf bats in Kibale National Park, Uganda.[2] prior to the COVID-19 pandemic, while looking for coronaviruses carried by bats.[3]
Etymology
Ruhugu virus was named after the Ruteete region of Uganda and the word in the local Tooro language, which describes "the flapping of bat wings in the hollow of a tree: obuhuguhugu"[3]
Structure
Ruhugu virus is closely related to Rubella virus and differs in only one amino acid in the protein it uses to get into host cells.[4] In the fusion protein of the virus and two putative T cell epitopes in the capsid protein of the ruhugu virus the amino acid sequences of four putative B cell epitopes are moderately to highly conserved, suggesting ruhugu viruses have a similar capacity for fusion with the host-cell membrane like rubella virus.[5]
