London, Europe Brief News- Over the past week, the UK has witnessed a rising in the Covid infections reaching more than one million.
There has been a 14% rise in people testing positive in the week to 20 September.
The new figures are the biggest increase since the summer.
But there is no clear evidence of an autumn Covid wave starting, says the Office for National Statistics (ONS).
More recent data showing a rise in hospital admissions with Covid-19 has been called “a wake-up call“.
Dr Thomas Waite, deputy chief medical officer for England, told BBC News that a number of new sub-variants of Omicron were circulating at low levels, and could be behind the hospital figures.
Daily hospital admissions are lower than where they were for much of July, but highest among the oldest age groups.
However, six out of 10 people with the virus in hospital receive treatment for something else – not Covid-19.
“The fact there are people getting so seriously ill they need to go into hospital is a wake-up call to us all that Covid is still here,” said Dr Waite.
Health experts have warned of a flu and Covid “twindemic” this winter, urging those who qualify to get their free jabs now.
