A NEW naming scheme for noteworthy Covid variants has been introduced by the World Health Organisation (WHO).

From now on the WHO will use Greek letters to refer to variants first discovered in countries like India, South Africa and the UK.

The UK variant is therefore labelled as Alpha, the South African Beta, and the Indian as Delta.

The United Nations health body said the move was to simplify discussions but also to help remove some stigma from the names.

It also follows criticism from the Indian government that labelling variants according to where they were first detected leads to increased stigmatisation.

"No country should be stigmatised for detecting and reporting variants," the WHO's Covid-19 technical lead, Maria Van Kerkhove, tweeted. She also called for "robust surveillance" of variants, and for the sharing of scientific data to help stop the spread.

The labels will refer to both variants of interest (VOI) and variants of concern (VOC) with the Greek alphabet chosen following "wide consultation and a review of several potential systems", according to Van Kerkhove.

She added that the labels do not replace existing scientific names such as B.1.1.7 which refers to the variant that was first identified in the UK. The new naming scheme is to help with public discussion of new variants.
