A UK study has discovered that a mutant Delta version of Covid-19 is less likely to show any symptoms, despite concerns about its greater transmissibility.

According to the study, the Covid-19 variation, which is classified as a Variant Under Investigation (VUI) in the UK, is less likely to show any symptoms.

The Delta AY is prevalent, according to the latest results from the long-running Real-time Assessment of Community Transmission [REACT-1] study.

Since September, the 4.2 variation has been growing at a rate of 2.8 percent each day, and it is responsible for some of England's high infection rate.

Imperial College London and Ipsos MORI conducted the study using swab tests conducted at home by over 100,000 adults in England between October 19 and November 5.

It was discovered that those infected with AY.4.2 were less likely to experience any of the "typical" symptoms of loss of taste or smell, fever, or a new persistent cough, as well as any other symptoms.
