II. Pathophysiology

  1. Flaviviridae are transmitted by arthropods (Group B Arbovirus, ticks or Mosquitos)
  2. Flaviviridae are enveloped, Icosahedral single stranded RNA Viruses
  3. Flaviviridae are Message Sense RNA Viruses (Positive Stranded, +ssRNA)
    1. Message sense RNA (+ssRNA) are identical to Messenger RNA (mRNA)
    2. Like mRNA, +ssRNA may be immediately translated by host ribosomes into Protein

III. Types: Genus Flavivirus
