The World Health Organization said it was closely tracking a Delta subvariant to determine whether it was more transmissible than the original strain, as Covid-19 cases rise globally.

It was also examining whether people were more resistant to the particular subvariant, called AY. 4.2, which has been detected in at least 42 countries.

“An increase in AY. 4.2 sequence submissions has been observed since July,” the WHO said in its weekly epidemiological update.

“Epidemiological and laboratory studies are ongoing” to see if there was a change in transmissibility of the variant, or a decrease in the ability of human antibodies to block the virus, said the WHO.

The subvariant, which some are calling “Delta Plus”, has been designated a Variant Under Investigation by the UK Health Security Agency. There was no evidence that it caused more severe disease or rendered vaccines ineffective.
