WHO confirms aerosol transmission of corona virus

Why is it in News?
  • WHO accepted the possibility of aerosol transmission in crowed places.
Details:
  • WHO acknowledged that the novel coronavirus can remain in the air in crowded indoor spaces.
  • In crowded places, short range aerosol transmission can happen.
  • However, WHO does not think that even in these situations, the virus was transmitted exclusively by the aerial route and it needs more research.
  • Previously acknowledged transmission modes:
(1) Respiratory Droplets transmission: 
(a) when an infected person coughs, sneezes, talks, or sings, such transmission happens. 
(b) It is still understood to be the primary mode of transmission.
(2) Fomite transmission
(a) It refers to transmission through infected surfaces.
(b) Surfaces include doorknobs, elevator buttons, handrails, phones, switches, pens, keyboards and, if not disinfected, even a doctor’s stethoscope.
  • It means that wearing a mask becomes even more important than earlier.
