NHS Faces Flu Treatment Crisis: No Proven Cures

The National Health Service (NHS) is grappling with a severe lack of proven treatments for flu patients admitted to hospitals. Professor Sir Peter Horby, who previously identified a COVID-19 treatment, is now leading trials to find effective flu therapies.

The current surge is fueled by a new H3N2 strain, referred to as 'superflu,' which poses a greater risk to older individuals. Despite a record number of flu hospitalisations, existing treatments like Tamiflu lack robust evidence for severe cases, unlike treatments developed for COVID-19.
