Delta variant is linked to 90% of Covid cases in UK
Variant first discovered in India is thought to spread more easily and be more resistant to vaccines
More than 90% of Covid cases in the UK are now down to the coronavirus Delta variant first discovered in India, data has revealed, as the total number of confirmed cases passed 42,000.
Also known as B.1.617.2, the Delta variant has been linked to a rise in Covid cases in the UK in the past weeks. It is believed to spread more easily than the Alpha variant, B.1.1.7, that was first detected in Kent, and is somewhat more resistant to Covid vaccines, particularly after just one dose. It may be also associated with a greater risk of hospitalisation.
