High-yield clue

Rodent-associated bunyavirus inhaled from aerosolized excreta; New World strains (e.g., deer mouse Sin Nombre) classically cause hantavirus pulmonary syndrome.

Overview

A negative-sense single-stranded RNA virus (genus Orthohantavirus, family Hantaviridae, order Bunyavirales) with a segmented genome, studied as a rodent-borne agent of pulmonary and renal syndromes.

Classification

  • Hantaviridae
  • Order Bunyavirales
  • Genus Orthohantavirus
  • Negative-sense ssRNA
  • Tri-segmented, enveloped

Lab & identification clues

  • Segmented negative-sense bunyavirus genome vocabulary
  • Hantavirus pulmonary syndrome (HPS) framing
  • Hemorrhagic fever with renal syndrome (HFRS) framing

Associations

  • Rodent reservoirs, each virus with its own host (deer mouse for Sin Nombre)
  • Inhalation of aerosolized rodent excreta transmission
  • Hantavirus pulmonary syndrome vocabulary (New World)
  • Hemorrhagic fever with renal syndrome vocabulary (Old World)

Commonly confused with

  • Lassa virus
  • Crimean-Congo hemorrhagic fever virus
