The NHS has issued a warning to Londoners about a potential “tidal wave” of flu, as new figures reveal a 61% increase in flu-related hospital admissions in just one week. An average of 144 beds in London were occupied by flu patients during the week leading up to December 8, compared to 89 the previous week.

With the NHS already grappling with a “quad-demic” of flu, Covid, norovirus, and RSV, experts are concerned that this winter could be one of the worst the health service has ever faced. Hospital capacity is under immense pressure, with some adult wards closing due to norovirus-like symptoms, and the number of children hospitalized with RSV also rising.

Professor Sir Stephen Powis, national medical director for NHS England, stressed the importance of flu vaccinations to avoid serious illness and reduce pressure on hospitals. He urged people to get vaccinated, with only one week remaining to book appointments before the festive period.

Dr. Layla McCay, director of policy at the NHS Confederation, warned of a “real risk” of the health service reaching crisis point unless there are improvements in social care capacity. Meanwhile, Health and Social Care Secretary Wes Streeting highlighted the government’s efforts to tackle waiting lists and urged those eligible for free vaccinations to get them as soon as possible to protect themselves and the NHS.
