UK Braces for Second Norovirus Wave as Cases Reach Record Highs

Health officials warn that a new strain could lead to reinfections, with hospitals and care homes facing significant strain.

Norovirus cases in the UK are at their highest levels since 2014, with laboratory-confirmed cases more than doubling the five-season average for this time of year.
The dominant strain has shifted from GII.17 to GII.4, raising concerns about reinfections as immunity to one strain does not protect against the other.
Hospitals report a 150% increase in bed occupancy due to norovirus compared to last year, adding pressure to an already strained healthcare system.
Older adults, young children, and immunocompromised individuals are most at risk of severe symptoms, prompting warnings to avoid hospitals and care homes if symptomatic.
Health experts emphasize the importance of handwashing with soap and water, as alcohol-based sanitizers are ineffective against the virus.
