The severity of the Delta strain is far more severe than any other variant, including a 2.5 times higher risk of hospitalization than the Alpha variant found in the UK first. Overall the strain found in India increases the risk of hospitalization by four folds as compared to the original.
The variant of concern designation is given to strains of the virus that scientists believe are more transmissible or can cause more severe disease. Vaccines, treatments, and tests that detect the virus may also be less effective against a variant of concern.
The World Health Organisation (WHO) classified the Delta variant as a variant of concern on May 10. A study on the Delta variant in Scotland published on Monday found that it was associated with about double the risk of hospitalization compared with the Alpha variant, B.1.1.7, that was first identified in the UK.
