Complete genome sequence of the Burana virus (BURV) was determined using the next-generation sequencing approach (ID GenBank KF801651). The prototype strain of BURV LEIV-Krg760 was originally isolated from the ticks Haemaphysalis punctata Canestrini et Fanzago, 1877 (Ixodidae, Haemaphysalinae), collected from cows in Tokmak wildlife sanctuary, eastern part of the Chu valley (43 degrees 10' N, 74 degrees 40' E) near Burana village, Kirgizia, in April 1971. Molecular genetics and phylogenetic analyses showed that the BURV belonged to the Nairovirus genus, Bunyaviridae and is related to Tamdy virus (TAMV) that is also associated with the ixodidae ticks of pasture biocenosis in Central Asia. Previous studies showed that TAMV is the prototypic virus of new phylogenetic Tamdy group in the Nairovirus genus. Thus, BURV was classified as a new virus of the Tamdy group, Nairovirus, Bunyaviridae.

Article Synopsis
- - Tick-borne viral diseases, particularly Tamdy virus (TAMV), are a growing public health issue, with limited understanding of TAMV's epidemiology and spill-over risk into humans.
- - Research in Xinjiang, China, found TAMV RNA in 4.7% of tick pools, with certain tick species identified as primary vectors, and evidence of TAMV exposure in animals dating back to 2006.
- - The study underscores TAMV's potential to infect multiple animal species via ticks, signaling a need for proactive public health measures to prevent the spread of emerging zoonotic diseases.

The prototype strain TAMV/LEIV-1308Uz was isolated for the very first time from the Hyalomma asiaticum asiaticum Schülce et Schlottke, 1929 (Ixodidae, Hyalomminae) collected in the August 1971 from sheep in the arid area near Namdybulak town (41 degrees 36' N, 64 degrees 39' E) in the Tamdinsky district of the Bukhara region (Uzbekistan). TAMV was revealed to be a prototype member of the new phylogenetic group within the limits of the Nairovirus.
