Don't Panic, Get Informed! Coronavirus - History & Prevention


  • Coronaviridae, a monophyletic cluster in nidovirales, RNA positive stranded enveloped virus.
  • Three classes of CoV
  1. Vertebrate : mammals ( Corona & Toro virus),
  2. Birds (Corona virus),
  3. Fish ( Bafiniviruses).
  • Measuring approximately from 120-160nm to 400-500microns.
  • Corona viruses are the largest RNA viruses identified so far.
  • Corona virus a threat to domestic animals & pets.
  1. Dog = canine corona virus type I & II
  2. Cat = feline corona virus type I & II
  3. Cow = bovine corona virus
  4. Horse = equine corona virus
  • Human corona virus exits with types 229E, NL63, OC43 and SARS related corona virus.
  • Regarding infectivity: In humans only E protein is identified as a virulent factor of corona family associated with SARS-CoV.
  • In humans corona virus targets primarily the epithelial cells of gastro intestinal and respiratory tract. Any pre existing infection in and around these tracts favours corona seeding.
  • Studies have shown that Rodent CoV can cause hepatitis with severe neurological infections resulting in paralysis & demyelisation leading to neuropathogesis of humans in multiple sclerosis.
  • Human corona viruses like beta corona virus ( HCoV-OC43) & alpha corona virus (HCoV-229E) isolated from common cold cases in humans


  • Corona virus is large in size, thus any mask prevents its entry so there is no need to use pharmacists to trade muzzles.
  • The virus does not settle in the air but is grounded, still gets transmitted by the air.
  • Coronavirus when it falls on a metal surface, it will live 12 hours, so washing hands with soap and water well enough.
  • Corona virus when it falls on the fabric remains 9 hours, so washing clothes or being exposed to the sun for two hours meets the purpose of killing it.
  • The virus lives on the hands for 10 minutes, so putting an alcohol sterilizer in the pocket meets the purpose of prevention.
  • And stay away from ice cream and eating cold is important.
  • Gargle with warm and salt water kills the tonsils’ germs and prevents them from leaking into the lungs.
  • Adherence to these instructions fulfills the purpose of preventing viruses.
