As of now, four new COVID variants have been detected in and around the world.
The first mutated virus, B.1.1.7, also known as the UK variant, was found in the south-east of England. Experts suggest that this variant was 40-70% more infectious than other variants and raises death risks to 60%.
Another new variant was detected in Brazil, that was believed to be more contagious and dangerous than the previous mutation. E484K, escape mutation allows the variant to dodge the antibodies.
B.1.351, the South African variant was found in at least 20 countries, including the United Kingdom. Akin to the Brazil variant, E484K mutation allows this variant to dodge antibodies. Additionally, N501 mutation makes it more contagious.
