Dhori virus (DHOV) is a species of the genus Thogotovirus and a member of the family Orthomyxoviridae. Its hosts are ticks, mosquitoes, and mammals (including humans). Dhori virus is lethal to mice, causing systemic pathologic changes similar to those reported in humans with virulent influenza A (H5N1) virus infection. Batken virus (BKNV) is considered a subtype of Dhori virus. Serological cross-reactions between Batken and Dhori viruses indicate a phylogenetic relationship between these viruses.
