A recent genome sampling of different strains of SARs CoV-2 in Uttar Pradesh has showed presence of the new Kappa variant.
The mutations of SARA CoV-2 have been named on Greek alphabets. Some of the prevalent strains include alpha, beta, gamma, delta, lambda etc.
The more prevalent Delta strain is majorly seen in Indian population. The Kappa strain is relatively new as WHO has recently given it the name.
The Kappa and Delta variant emerged from the same mutant variant of the Wuhan Virus known as B.1.617. It was also known as double mutant.
Earlier, the new strains were named on the country of origin. The UK variant, Brazil variant, India variant, South Africa variant were all mutated versions.
The WHO decided to drop country-specific names after opposition from these countries. They were given identity-neutral names based on Greek letters.
The B.1.617 further mutated into three more variants. They were named as B.1.617.1, B.1.617.2, and B.1.617.3.
B.1.617.1 is named the Kappa, the B.1.617.2 as Delta but the B.1.617.3 was not given any name as it was less prevalent.
The initial lineage of Kappa variant belongs to Vidharba region that first showed the origin of B.1.617 strain.
Authorities have said that the Kappa variant does not pose any threat as it was already present in population. There would not be increased threats.
It is also believed that the kappa variant is less dangerous than Delta variant and hence seeing lower prevalence among population.
The Kappa variant is termed as “variant of interest” whereas the Delta is known as “variant of concern”. Currently it is present in small pockets of the country.
