The industry group warned of shortages of both branded and generic medicines used to treat seasonal illnesses. It comes after the UK Health Security Agency warned that winter illnesses, including flu and COVID-19, continue to circulate at “high levels.

After receiving delivery of small oxygen cylinders on Tuesday, the East of England Ambulance Service urged staff to “take sensible steps” to conserve supplies. According to the Health Service Journal (HSJ), the trust informed staff in December that its oxygen suppliers were unable to fulfil its orders.

While there is no shortage of oxygen, the NHS is seeing significant demand for portable oxygen due to increased numbers of patients suffering from respiratory viruses such as flu and Covid-19,” an NHS spokesperson said. Local areas are using the existing supply as efficiently as possible, while suppliers are working with the NHS to help meet increased demand – anyone needing care should not hesitate to contact the NHS as they normally would.” It comes as NHS managers in one area consider using “field hospitals” to deal with the influx of patients.

Dr Whiteman’s email, obtained by The Sunday Times and seen by the BBC, began with the statement: “Call to arms. It highlighted how busy the acute units in her board’s operational area, which included Bedford, Milton Keynes, Luton, and Dunstable Hospitals. She promised in the message that if employees stepped forward to help colleagues, they would receive training and induction. The region’s hospitals have seen an increase in the number of people presenting with Covid and flu symptoms. Patients with these infections now occupy one in every eight beds in England.
