About Zika Virus:

  • Zika virus disease is spread by daytime-active Aedes mosquitoes, such as A. aegypti and A. albopictus.
  • Its name comes from the Ziika Forest of Uganda, where the virus was first isolated in 1947.
  • Zika virus shares a genus with the dengue, yellow fever, Japanese encephalitis, and West Nile viruses.
  • Since the 1950s, it has been known to occur within a narrow equatorial belt from Africa to Asia and from 2007 to 2016, the virus spread eastward, across the Pacific Ocean to the Americas.
  • The infection, known as Zika fever or Zika virus disease, often causes no or only mild symptoms, similar to a very mild form of dengue fever.
  • While there is no specific treatment, paracetamol (acetaminophen) and rest may help with the symptoms.
  •  Zika can spread from a pregnant woman to her baby.
  • This can result in microcephaly, severe brain malformations, and other birth defects.
  •  Zika infections in adults may result rarely in Guillain–Barré syndrome, a rapid-onset muscle weakness caused by the immune system damaging the peripheral nervous system.
