With infection rates rising across the UK, the country is "not where we would want to be going into Christmas", a leading epidemiologist has warned.
Speaking to BBC Radio 4's World at One, Prof Neil Ferguson said trends were "disturbing" and warned the country was "heading into the worst time of year for transmission of respiratory viruses".
But he said there was some hope over the Christmas period with schools being closed.
"What we have seen is the rapid increase in cases in teenagers and younger children so there will be some dampening in transmission," the former government adviser said

The UK R number, the rate at which the virus is spread, has increased to between 1.1 and 1.2, the government has said.
Last week the rate was given as between 0.9 and 1.0.
A number above 1 means that the virus is spreading "exponentially".
The estimated R rate for England is between 1.1 and 1.3 with the east of England the worst affected, with a number between 1.2 and 1.4.
The Scientific Advisory Group for Emergencies (SAGE) said these estimates represent the transmission of Covid-19 over the past few weeks due to the time delay between someone being infected, having symptoms, and needing healthcare
