Corona Virus

From keywordswiki

  • Coronaviruses are a group of viruses that cause diseases in mammals, including humans, and birds. In humans, the virus causes respiratory infections which are typically mild but, in rare cases, can be lethal.
  • There are no vaccines or antiviral drugs that are approved for prevention or treatment.
  • The genomic size of coronaviruses ranges from approximately 26 to 32 kilobases, the largest for an RNA virus.
  • The name "coronavirus" is derived from the Latin corona and the Greek κορώνη (korṓnē, "garland, wreath"), meaning crown or halo. This refers to the characteristic appearance of virions (the infective form of the virus) by electron microscopy, which have a fringe of large, bulbous surface projections creating an image reminiscent of a royal crown or of the solar corona.
