An Arbovirus is a virus transmitted primarily by an arthropod

  • Comes from ARthropod-BOrne virus
  • Arthropods include: mosquitos, ticks, sandflies
  • Can have rare person-to-person transmission
    • Blood borne
      • Transfusion, sharing needles
    • Organ transplantation
    • Breast feeding
    • Intrauterine
    • Sexual transmission

There are a number of major arbovirus families:

  • Family Bunyaviridae
    • Rift Valley, Crimean–Congo hemorrhagic
  • Family Flaviviridae
    • Dengue, West Nile, Zika, Yellow Fever
  • Family Reoviridae
    • Equine encephalosis
  • Family Togaviridae
