Mutations of Covid-19 have been sparking concern around the globe with new strains spotted in several countries. One of these originated in England, but the latest has come from Brazil and was first identified in Japan. This week Prime Minister Boris Johnson said he is concerned about the new coronavirus variant which is believed to have emerged in Brazil but he stopped short of imposing a precautionary travel ban.
There are two notable ways in which the novel coronavirus can mutate.
Both happen in the spike protein, which is like a key that the virus uses to enter cells inside a body.
The first is called mutation N501 and alters part of the spike protein called the receptor-binding domain , which is where the virus first makes contact with the body s cells.
The mutation helps the virus enter the cell more easily.
The other mutation is called H69/V70 deletion, which has been found several times including in mink.
Work is ongoing to find out how this mutation will change the way the virus interacts with human bodies.
