A TOP UK health boss has urged people to wear masks or stay home if they are suffering from a cold or flu.
The warning from Professor Susan Hopkins, the chief medical adviser at the UK Health Security Agency (UKHSA), comes as extreme pressure is placed on NHS services by “high levels” of Covid-19, flu, and scarlet fever.
The health service across the UK is buckling under the strain, with more than a dozen NHS trusts and ambulance services declaring critical incidents over the festive period.
