Overview

• Latest surveillance shows XFG (Stratus) at 35% and NB.1.8.1 (Nimbus) at 28% of sequenced cases.
• Reported infections have roughly doubled over four weeks, and hospital admissions rose from 2.0 to 2.73 per 100,000.
• UKHSA reissued advice to stay home if symptomatic, avoid crowded or poorly ventilated places, and wear a well-fitting face covering if you must go out.
• People aged 75 and over and those with weakened immune systems can get a free NHS vaccine, which officials say still offers good protection against these variants.
• Reports highlight a hoarse voice or “razor blade” sore throat as a tell‑tale early sign alongside common respiratory symptoms.
