Mengla dianlovirus (MLAV, also written Měnglà virus) is a type of filovirus identified in a Rousettus bat in Mengla County, Yunnan Province, China and first reported in January 2019.[1] It is classified in the same family as Ebolavirus and Marburgvirus.[2]
It is the only member of the genus Dianlovirus.[1] The name derives from 滇 (diān), the Chinese language abbreviation for Yunnan, added to "filovirus", the common name for Filoviridae.[1] Neither the species nor the genus are listed in the 2018 ICTV classification, as the virus was formally described after that report was released.[3] A formal proposal was submitted for the taxa in January 2019.[4]
