Health experts have warned that the recent rise in Methicillin-resistant Staphylococcus aureus (MRSA) cases in England is being fuelled by infections among younger and healthier people, particularly those involved in sports and gym activities.
MRSA is a leading cause of bacterial infections and is resistant to treatment, especially with existing antibiotics.
Traditionally, the superbug, MRSA, has been more closely associated with hospital patients who are older or already unwell.
But new surveillance data suggests that community transmission is shifting towards younger age groups, says the Independent report.
Nearly one in four people infected in 2023-24 were under the age of 45, compared with only around one in ten in 2007-08.
Researchers say the trend raises concerns that fitness environments such as gyms, locker rooms and sports clubs are becoming breeding grounds for the bacteria, which spreads easily through shared equipment, skin contact and small cuts or abrasions.

The figures come as the UK Health and Security Agency (UKHSA) continues to track a sharp increase in cases outside of hospitals.
Between January and March this year, 175 community-onset cases were recorded, up almost 40 per cent on the same quarter in 2019.
Officials have urged people to practise good hygiene, including washing hands regularly and avoiding the sharing of personal items like towels and razors, to help limit further spread.
