A new variant of the Covid-19 virus has been detected in France, it is said to be more contagious.

Named IHU, the new B.1.640.2 variant has so far infected 12 people living in south-eastern France. It is referred to as 'IHU' as it was detected by researchers at Instituts Hospitalo-Universitaires (IHU) Mediterranee Infection.

Why is IHU concerning?

Genetic lineages of SARS-CoV-2 have been emerging and circulating around the world since the beginning of the Covid-19 pandemic. Delta and Omicron are the two variants of concern so far identified by the Centers for Disease Control and Prevention.


A genetic analysis of the variant found that it contains 46 mutations and 37 deletions from the original SARS-CoV-2. Of those, there are 14 amino acid substitutions and nine deletions on the spike protein, which is what SARS-CoV-2 uses to latch onto your cells.

Amino acids are molecules that combine to form proteins, and both are the building blocks of life. In genetics, a deletion is a mutation in which a part of a chromosome or a sequence of DNA is left out during DNA replication.

The B.1.640.2 has not been identified in other countries so far or labelled a variant under investigation by the World Health Organization (WHO).
