A new coronavirus strain, Stratus, is spreading rapidly across the UK and could soon become the dominant variant, health experts have warned. Officially classified as XFG, Stratus is a subvariant of Omicron, and early indications suggest it may be more contagious than previous COVID-19 strains.
The emergence of Stratus highlights the ongoing need for vigilance, even as vaccination efforts continue to reduce the severity of cases globally.
