Overview
- UKHSA data show XFG (Stratus) and NB.1.8.1 (Nimbus) are now the most common lineages, with XFG and its offshoots making up about 77% of cases in England.
- People with respiratory symptoms are urged to avoid contact with vulnerable individuals and stay home if possible, with masks and hygiene measures advised when going out.
- Test positivity in England rose from 7.6% to 8.4% in a week, and Covid hospital admissions increased from 2.00 to 2.73 per 100,000.
- Clinicians report a hoarse or croaky voice as a frequent early sign of Stratus, while Nimbus is often linked to a severe 'razor blade' sore throat and more gastrointestinal symptoms.
- Authorities say current vaccines remain protective against severe disease, winter jab appointments open for eligible groups from October 1, and WHO continues to monitor other lineages such as BA.3.2 for potential antibody evasion.
