The elderly are now beginning to feel the effects of the Omicron wave, which will send shudders through the NHS.
The latest COVID surveillance report from the UK Health Security Agency shows a steep rise in the number of over 85s being admitted to hospital in England.
Hospitalisations in the age group doubled from 62 in every 100,00 in the week leading up to Christmas to 121 in every 100,000 a week later.
Rates were also up sharply in the 75-84s, rising from 28 to 57 per 100,000.
Rates in younger people were lower and rising more slowly.
The figures suggest the surge, which began in young people, has moved up the generations to affect those more vulnerable to serious disease.
The NHS is already feeling the pressure, with several hospitals declaring major incidents. But high case rates and the shifting demographic suggests admissions will rise further in the coming weeks.
