According to the latest update, PHE said there were 42,323 cases of variants that first occurred in India, up from 12,431 cases per week to June 3.
This variant is now predominant throughout the UK and is believed to be 60% more transmissible than the Alpha variant that began in Kent.
It accounts for more than 90% of new Covid-19 cases in the UK, and the rate of increase in infection across the region shows a doubling time of 4.5 to 11.5 days.
However, PHE said it was “encouraging” to confirm that the proportion of patients hospitalized for Covid-19 did not yet show similar growth rates. He said the deployment of vaccination has helped mitigate the effects of two vaccinated people, primarily high-risk elderly groups.
The Delta variant has a high ability to evade vaccine immunity with a single dose, with only 33% protection against infection. It rises to 80% after the second dose.
Dr. Jenny Harries, Chief Executive Officer of the UK Health and Security Agency, said: If you qualify, it is advisable to go ahead and vaccinate. Remember that two doses provide much more protection than one dose.
“But vaccination reduces the risk of serious illness, but does not eliminate it. Delta is much more infectious than alpha, so it has not changed public health. Following hygiene advice is as important as ever. You can be vaccinated, work from home and always remember “hands, face, space, fresh air”. These measures work and save lives. “
