Indian COVID Delta variant cases doubling every 4.5 days in parts of England
Public Health England (PHE) said today that 42,323 cases of the Delta variant have been confirmed in the UK, up by 29,892 from last week.
Growth rates for Delta cases are high across all parts of the country, it added, with regional estimates for doubling time ranging from 4.5 days to 11.5 days.
The growth rate was shortest in the West Midlands and Yorkshire and the Humber and longest in the East of England, PHE said.
In England 39,061 cases of the Delta variant have been confirmed, along with 3,035 in Scotland, 184 in Wales and 43 in Northern Ireland.
PHE also said that more than 90% of new Covid-19 cases are now the Delta variant, with new research suggesting it is associated with an approximately 60% increased risk of household transmission compared with the Alpha or Kent strain.
But it added that the increase in confirmed cases from 12,341 last week has been driven partly by a reduction in test turnaround times and a faster process for identifying cases of the variant. ■
