Coronavirus: Researchers warn of new delta mutation AY.3

The coronavirus continues to mutate. “AY.3” is on the advance in the USA, Great Britain and Israel. This is a sub-variant of the well-known Delta variant, writes the “Mirrors”.

Since this form of the virus has only been spreading for a few weeks, the number of cases is still low. Still, AY.3 could be more contagious than Delta, the researchers warn. This is what the available data would suggest. “These are definitely the first clear signs of a potentially worrying variant in a while,” wrote Christina Pagel, a professor at University College London, on Twitter.
