Given the number of times this has happened already, it should come as little surprise that we’re now faced with yet another new subvariant of SARS-CoV-2, the virus responsible for COVID.
This new subvariant is known as XFG (nicknamed “Stratus”) and the World Health Organization (WHO) designated it a “variant under monitoring” in late June. XFG is a subvariant of Omicron, of which there are now more than 1,000.
