London: The number of people infected with the coronavirus is increasing rapidly in England, doubling every 11 days, which coincides with the Delta variant of Covid-19 becoming dominant in the country, a new study reports on Thursday. The Imperial College London led Real-time Assessment of Community Transmission (REACT-1) analysis, based on over 100,000 home swab tests taken between May 20 and June 7, estimates that 0.15 per cent of people have the deadly virus, or roughly 1 in 670. It found that the link between infections, hospitalisations and deaths had been weakening since February, but since late April, the trend has been reversing for hospitalisations.

"We found strong evidence for exponential growth in infection from late May to early June in the REACT-1 study, with a doubling time of 11 days on average for England," said Professor Paul Elliott, director of the REACT programme from Imperial's School of Public Health. "These data coincide with the Delta variant becoming dominant and show the importance of continuing to monitor infection rates and variants of concern in the community," he said.

The findings come days after UK Prime Minister Boris Johnson announced a month-long delay to an end to lockdown restrictions, citing the rising number of cases of the Delta variant – first identified in India. "These findings highlight the stark context in which we took the difficult decision to delay Step 4 of the roadmap out of lockdown," said UK Health Secretary Matt Hancock. "Cases are now rising, but thanks to our incredible vaccination programme and enhanced response package including surge testing, we have the tools to curb the spread of this virus.

We all must hold our nerve that little bit longer as our vaccine rollout continues and I urge everyone to keep observing hands, face, space and fresh air, and make sure you receive both doses of the vaccine for the best possible protection," he said. The Imperial study scientists estimate that the reproduction number, or R number, of the deadly virus is now well above one at 1.44, meaning 10 infected people would pass the virus on to 14 others on average, resulting in fast growth of the epidemic.
