Covid-19 cases are rising among the over-55s in England, a study has found, with increased social contact, waning of booster protection and a more contagious subvariant of Omicron possibly driving an increase in hospitalisations.
The Imperial College London REACT study, conducted from Feb 8 to March 1, found that Covid-19 prevalence was 2.88 per cent, compared to 4.41pc in January, according to a Reuters report.
But while prevalence fell in under-17s and 18-54-year-olds during February, for those 55 and older, it was estimated to have increased over the month.
