Nihala Naseefa CH and Sheeba P

The newly emerged corona virus is in its highest peak of action and various unseen forms of the same are being
identified, which can transmit and spread the disease in a higher pace than the earlier discovered one. There are
numerous alternatives of the SARS COV-2 that differ from each other by at a minimum of one alteration. Many of
these variants soon gets extinguished while some others remain longer, spread fast, procure further mutations and
undergo variation to a new alternant form. This paper incorporates details about these newly identified variants of
SARS COV-2 in different nooks of the world. In addition, the association of blood type with SARS COV-2 and the risk
factors related to this has also been addressed. People having blood group ‘O’ are a bit more resistant and have
comparatively a higher degree of tolerance towards the attack of novel corona virus, on the other hand those having
‘A’ blood type are typically more susceptible to the viral attack.
