Overview

• UK surveillance shows XFG, nicknamed Stratus, is now the most common lineage, with Nimbus (NB.1.8.1) also widespread and recent TV guidance citing roughly 63% versus 25% case shares.
• UKHSA reports the weekly Covid hospital admission rate has risen to 2.73 per 100,000 from 2.00 the week prior.
• CDC wastewater tracking shows national viral activity at a moderate level, with 19 U.S. states reporting high or very high readings.
• Clinicians highlight throat‑centred symptoms including a hoarse voice and an intense “razor blade” sore throat, alongside familiar signs such as cough, congestion, headache and fatigue.
• WHO lists Stratus as a variant under monitoring and assesses low global risk, and health agencies advise staying home when ill, wearing a face covering if you must go out and getting the current seasonal Covid and flu vaccines.
