The Stratus COVID-19 variant, which includes the XFG and XFG.3 strains, currently accounts for around 30 per cent of COVID-19 cases across England. A unique symptom associated with the Stratus variant is a hoarse voice, although the symptoms associated with it are usually mild to moderate. Experts suggest Stratus may be able to evade immunity from previous infections or vaccinations.
