Coronavirus must be taken very seriously again or the UK will face "a bumpy ride over the next few months", a deputy chief medical officer has warned after a "big change" in infections.
Professor Jonathan Van-Tam said that the public had "relaxed too much" over the summer and described the rising number of cases were of "great concern".
The deputy chief medical officer for England issued the warning as Caerphilly in south Wales prepared to be placed under local lockdown and stricter measures were extended in Scotland.
There were a further 2,948 lab-confirmed cases of coronavirus in the UK as of yesterday morning, following the 2,988 reported on Sunday, which was the largest daily figure since May.
