Covid strains

The new studies says the UK variant or the Kent variant — B.1.1.7 — spreads more easily and quickly than other variants

As the covid cases across the nation is again on rise and the numver of activecase is being reported again, it has become mandatory to keep precautions. Apart from, the new variant of covid has also been found in India, it has become important to understand how the symptoms of new variants are different from the original one.

The new studies says the UK variant or the Kent variant — B.1.1.7 — spreads more easily and quickly than other variants.The UK-based New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG) recently reported that the Kent variant may be up to 70 per cent more deadly than previous strains.


In South Africa, another variant called B.1.351 emerged independently of B.1.1.7.

A variant called P.1 emerged that was first identified in travellers from Brazil, who were tested during routine screening at an airport in Japan, in early January.

This variant contains a set of additional mutations that may affect its ability to be recognised by antibodies.

According to various reports, the three variants carry the same genetic mutation – E484K – that allows it to evade the immune defences in the body, leading to infection.

Viruses have a tendency to mutate, all we have to do is to ensure safety and required precautions to reduce the risk. A factor called virulence, which means the ability of a microbial strain to cause disease.
