caption_attribution_description: English: Maximum parsimony phylogram indicating the relationship of deer tick virus to other tick-borne encephalitis group viruses. Values above branches indicate bootstrapped confidence values. Branch lengths are proportional to percent similarity in sequence. TBE, tick borne encephalitis; TSE, Turkish sheep encephalitis; GGE, Greek goat encephalitis; LI, louping ill virus; SSE, Spanish sheep encephalitis; KFD, Kyasanur Forest disease virus; TYU, Tyuleniy virus; SRE, Saumarez Reef virus. The topology of the phylogram that was independently derived from NS-5 does not differ from that of env and is not presented.
context_page_description: Deer tick virus is a virus in the genus Flavivirus spread via ticks that causes encephalitis.
context_section_description: DTV closely resembles Powassan virus (to which it has 84% nucleotide sequence identity and 94% amino acid sequence identity).
  Due to their close similarities, DTV is also called Powassan virus lineage II. The DTV lineage is presumed to be maintained between Ixodes scapularis, or deer ticks, and the white-footed mouse (Peromyscus leucopus).
