Overview

• UKHSA data indicate XFG (Stratus) and its offshoots now account for about three-quarters of sequenced Covid cases in England.
• Reported infections in England rose roughly 7 to 8 percent in early September, with some datasets also showing increases in hospital admissions and deaths.
• Clinicians report an early hallmark of Stratus as a hoarse or raspy voice and very sore throat, with some patients also noting gastrointestinal symptoms such as nausea and reflux.
• WHO lists XFG as a variant under monitoring and says current evidence does not show increased intrinsic severity, with approved vaccines expected to retain protection against severe outcomes.
• Health services are preparing targeted autumn boosters for high‑risk groups and reinforcing basic precautions such as ventilation, masking in crowded settings, and staying home when unwell.
