Corona virus mutating continuously. Here you know about the new strains of corona virus , how they mutate and discover first and how they affect the human life.

1. NEW STRAINS OF CORONA VIRUS
Strains of Corona virus

The corona virus at the root of COVID-19 is the newest known member of this family. At their
core ,corona virus contain a genetic blue print called RNA , similar to DNA .
The single stranded RNA acts as a molecular message that enables production of protein
needed for other elements of the virus.
Encapsulating the RNA genome is the viral envelope which protects the virus when it is outside
of a host cell . This outer envelope is made from a layer of lipid ,a waxy barrier containing fat
molecules.
The bulbous projections seen on the outside of the corona virus are spike proteins (red orange).
This fringe of proteins gives the virus its crown like appearance under the microscope from
which the latin name corona derived.

2. • Multiple variants of the virus that causes COVID-19 are circulating globally. In collaboration with
SARS -COV-2 Interagency Group (SIG) for SARS - COV -2 variants being monitored:

Unique facts
It can produce nearly 10x more viral load than in other covid-19 infected persons.
It showed 1.4-2.2 times higher transmissibility.
This strain is more successful in infectingyounger humans;can be 10-80% more lethal.
capable of ivading 25-61% of immunity from original strain.

Unique fact
It has Approx. 20% increased transmissibility
Less susceptible.
