Concern is ramping up around the country about the surge in flu cases which has been shutting schools and threatens to overwhelm hospitals and the NHS.

The UK is seeing record numbers of cases for this time of year – the spike coming earlier than previous years.

This includes record numbers of patients – nearing 3,000 – being hospitalised with the virus.

The scenario has led to urgent pleas from health officials to increase take-up of vaccinations.
