A new Covid-19 variant, named Stratus, is spreading rapidly across the UK, presenting a subtle initial symptom that may be easily overlooked. The variant, which includes two sub-lineages XFG and XFG.3, now accounts for 76.1% of recorded infections in Ireland, up from 49.3% six weeks prior. In England, XFG.3 represented 40% of cases as of June.
The most common early warning sign of Stratus is a hoarse or gravelly voice, according to Harley Street GP Dr Kaywaan Khan. This symptom may later develop into more familiar Covid signs such as fever or cough. Infectious disease specialist Dr Peter Chin-Hong noted that Stratus displays a wider range of symptoms, including sore throats, blocked noses, digestive issues, and exhaustion.
Despite the emergence of new symptoms, the UK's official Covid guidance remains unchanged. The government advises those with Covid-19 to stay at home, noting that most people cannot access free tests but can purchase them from shops. Vaccination remains available through the NHS.
The World Health Organisation classifies Stratus as a 'variant under monitoring'. While not believed to cause more severe illness, it is more transmissible than earlier strains. Health authorities recorded 425 new infections in Ireland during the first week of September, with Stratus thought to be behind the majority of cases.
