What is the Delta variant?

There are a few variants that originated in India circulating, but one is causing more worry than others.

The strain – B1617.2 (or the Delta variant) – is one of three related variants that have been detected in the UK. The others are B1617.1 and B1617.3.

There were originally four variants of concern (VOCs) in England – the so-called Kent, South Africa, Brazil and Bristol variants.

All three variants from India were originally designated as variants under investigation, however Public Health England (PHE) confirmed B1617.2 had become the fifth variant of concern as of May 7 due to rising cases.
