UKHSA warns adults to ‘stay home’ or ‘wear face covering’ when going out if feeling unwell

Professor Susan Hopkins, chief medical adviser at the UKHSA, listed numerous precautions in order to limit the spread of illness, as cases of scarlet fever and COVID-19 circulate at “high levels”.

The advice comes as a senior NHS boss on Monday warned the health service is under “unbearable strain” as pressure is mounting on the government to take action.

Matthew Taylor, head of the NHS Confederation, told Sky News that most NHS leaders say “this is the toughest winter they’ve ever dealt with” – adding: “We cannot go on like this.”

Critical incidents have also been called in at least seven health trusts, Sky News understands.

The UKHSA warned that both flu and COVID-19 are currently “circulating at high levels”, which is likely to continue to increase in coming weeks.

Tim Spector, professor of genetic epidemiology at King’s College London and founder of the COVID Zoe app, also highlighted an Omicron variant after a scientist said cases had more than doubled in America in a week.

High numbers of scarlet fever, which is caused by group A Streptococcus (Strep A), also continue to be reported in the UK. At least 30 children in the UK have died from invasive Strep A, and across all age groups in England, there have been 122 fatalities.

Other ways in which illness can be prevented from spreading includes “catching coughs and sneezes in tissues then binning them”, getting children to practice good hygiene, and getting a flu vaccination.

“Remember that flu vaccination is still available for all eligible groups and is the best protection against the virus,” Prof Hopkins urged.

“We have seen good uptake in older age groups, but vaccination among young children remains low.

“Flu can be very unpleasant and in some cases can lead to more serious illness. Getting your child vaccinated protects them and others they come into contact with, and it’s still not too late.”
