The UK faces a "rough winter" due to the combination of coronavirus, flu and other respiratory conditions that will make a comeback and face masks may be required in cities like Liverpool, a leading expert has said.
Calum Semple, a member of the Scientific Advisory Group for Emergencies (Sage) and professor of child health and outbreak medicine at the University of Liverpool, told BBC Breakfast "it's not just going to be coronavirus that's causing us trouble", and suggested face masks may need to be brought back in some regions.
He said: "The other seasonal viruses are going to come back.

"Hand hygiene and social distancing reduced influenza, it got rid of influenza, and many of the other viruses.
"Now that we're opening up society, we've got to live with not just covid but the flu will come back, RSV (respiratory syncytial virus) bronchiolitis will come back, so I think we're going to have a bit of a rough winter."
Asked how Christmas might compare to last year, he said: "I really don't know... but I can predict that the NHS is going to have a really tough time and it wouldn't surprise me if local directors of public health may be suggesting use of face masks in shops and on public transport.
"That's the kind of thing that I would expect - some degree of regional common sense approach. If you see a high amount of virus in Liverpool or Manchester or Birmingham, then it wouldn't surprise me if there was local leadership in that area."
He said the forthcoming Covid-19 booster jab campaign will "make a difference for a few people that are frail and elderly and have high risks, where their immunity might just need a bit of boosting, and it's to try and give them an extra leg up to protect them".
Professor Semple's comments come ahead of major announcements from Boris Johnson and his government today about how the pandemic and NHS pressures will be managed in the difficult months ahead.
We are expecting to hear from Health Secretary Sajid Javid around lunchtime, before a press conference with Boris Johnson and his top medical and scientific advisers later in the day.
