Following the rise in the cases, the Centre decided to step in ahead of the festival season as fears of COVID-19 third wave mounts.

“A team is investigating the new COVID19 variant AY.4.2. ICMR and NCDC teams study and analyze the different variants,” Union Health Minister Mansukh Mandaviya told ANI. 

Also, the Centre has issued several guidelines to curb the possibility of a third COVID-19 wave.

AY.4.2 has grown steadily in volume and now accounts for about 9 per cent of UK cases in the last 28 days. It has also been observed in a few European nations like Denmark, Germany and Ireland.

AY.4.2, one of 45 sub-lineages of Delta and dubbed by many as Delta plus, is likely to be named as Nu.

According to British scientists, it may be up to 15 per cent more transmissible than the original Delta and according to a report by Daily Mail, its prevalence in England doubled in a month from being behind four per cent of cases in September to 8.9 per cent in the two weeks to October 9.

What is the AY.4.2 variant?

AY.4.2 is a descendant of the Delta variant of Covid-19. The Delta variant, also known as B.1.617.2, was first identified in India in October 2020. The AY.4.2 sub-lineage contains two mutations in its spike protein - A222V and Y145H. According to the report, the UKHSA gave Delta sub-lineage AY.4. the official name VUI-21OCT-01. 

Does AY.4.2 cause more severe illness?

There is no clear indication from the UK that AY.4.2 leads to more severe illness, according to initial analyses.
