As NHS England revealed that accident and emergency departments had last week failed to meet targets to see 95% of patients within four hours, it warned that the service would continue to be under pressure for the next few weeks.
Dr Sarah Pinto-Duschinsky said that the flu season meant the NHS had been treating "more patients than than ever before."
Last week, 407,239 patients went to A&E - almost 4,000 more than the previous week and an increase of almost 20,000 on the same week a year ago.
The NHS continues to face unprecedented pressures on its frontline services - with almost 20,000 more A&E attendances than last year - and more than 105,000 people admitted to hospital which is one of the highest figures on record.
The extra £700 million invested has bought 700 more doctors, 4,500 more nurses, creating over 5,000 more beds.
Flu is now at its highest peak for the last three winters which is one of the reasons why over the New Year holiday we continued to treat more patients than ever before.
This means the NHS will continue to be under pressure for the next few weeks. Even at this stage of the winter it is still worth people getting their flu jab if they have not done so, and get advice from their pharmacist for colds, coughs and minor conditions.
