A croaky voice and a razor-blade sore throat are emerging as tell-tale symptoms of new Covid variants sweeping Britain and the US. The strains — XFB (“Stratus”) and NB.1.8.1 (“Nimbus”) — have driven infections to double since August. UK positivity has risen from 7.6% to 8.4%, with hospital admissions climbing.
In the US, wastewater data show moderate spread overall, though four states report very high levels. Patients describe severe throat pain, alongside headaches, fatigue and coughs. Experts stress these strains spread faster but aren’t more dangerous. Vaccination campaigns urge millions to get Covid and flu jabs, especially the vulnerable. Some chemists offer private vaccines at up to £99. Officials advise those with symptoms to stay home or wear masks.
