A new Covid variant called XFG, tagged on social media as 'American Covid' or 'Stratus Covid', is spreading in the United Kingdom. Hospitalisations linked to the variant have risen more than 400% in a single month, according to coverage by The Independent and the Daily Mirror.

Health media in the UK and India are raising concerns as one that can last several weeks, with two symptoms drawing particular attention online. Officials have yet to issue formal advice, but the sharp increase in hospitalisations has prompted alerts across health and news platforms.
