What are Flaviviruses?

Aug. 18, 2024

A recent study has now identified a protein named importin-7 (IPO7), as a carrier that transports flavivirus core protein through the nuclear membrane and into the nucleus.

About Flaviviruses:

  • Flavivirus is any virus belonging to the family Flaviviridae.
  • Flaviviruses have enveloped and spherical virions (virus particles) that are between 40 and 60 nanometers in diameter.
  • The flavivirus genome consists of nonsegmented single-stranded positive-sense RNA (ribonucleic acid).
  • Flaviviruses, when introduced into the human body, cause diseases, including neuroinfections, that can lead to serious metabolic consequences and even death.
  • Among the most dangerous and deadly members of the Flavivirus Family are Yellow Fever virus, Dengue virus, Zika virus, West Nile virus, Japanese Encephalitis virus, Tick-Borne Encephalitis virus, Kyasanur Forest virus, Alkhurma virus, and Omsk virus.
  • Aedes mosquitoes are the main vectors of many Flaviviruses and are primarily responsible for the spread of viral outbreaks of Dengue, Zika, and Yellow Fever.
  • Mosquitoes are not the only carriers, however. Ticks and other flying insects can also transmit these and other Flaviviruses from person to person and from animals to people.
  • Hepatitis C, the only non-vector-borne member of the Flavivirus family, is transmitted exclusively through direct blood-to-blood contact between humans.
