A new Covid strain called Stratus is spreading in the UK, characterized by the unique symptom of a hoarse voice. It has two variants, XFG and XFG.3, with XFG.3 being the more dominant variant, representing around 30 percent of Covid-19 cases in England, as reported by the UK Health Security Agency (UKHSA). Experts express concern over its infectiousness, but there is currently no evidence indicating that these variants lead to more severe illness compared to earlier ones, or that existing vaccines might be ineffective against them.
