A newly emerging Covid variant called ‘Stratus’ is spreading swiftly and exhibits a distinctive symptom that differentiates it from other strains. This strain, comprising two variants, XFG and XFG.3, was first detected in January. By June, the World Health Organisation (WHO) categorized XFG as ‘under monitoring’ due to its growing prevalence worldwide.
On September 3, the UK Health Security Agency recorded a 7.1% rise in coronavirus cases across England compared to the previous week, though it’s not specified how many of these are attributed to the XFG strain. In Ireland, health specialists noted 425 new cases in the early days of September, primarily driven by the XFG variant. Typically, Covid symptoms resemble those of common respiratory illnesses like the flu, including fever, cough, sneezing, or a runny nose.
Symptoms vary from case to case, with some experiencing minor to severe signs, reports the Mirror.
Nevertheless, the primary early symptom of Stratus is a hoarse or raspy voice, which might appear before the more common Covid symptoms. This unusual initial sign can lead to the variant being overlooked.
Medical experts have also recorded a host of additional symptoms, including blocked noses, painful throats, digestive issues and exhaustion.
Dr. Gareth Nye stated: “In many respects, it’s almost the same. However, individuals with this version are more prone to experiencing very sore throats and a hoarse voice, unlike the more general symptoms such as cough, fever, and body aches.”
“Illnesses always see spikes as children go back to school, as close contact and often lower personal hygiene levels mix.”
He further explained: “This variant seems more likely to cause illness, as it appears capable of evading your immune system even if you’ve been infected before. This makes existing vaccines less effective, highlighting the importance of keeping up with vaccinations against the latest coronavirus strains. It’s comparable to updating your phone for the best possible performance.”
Infectious disease expert Dr. Peter Chin-Hong from the University of California, San Francisco, cautioned that Stratus presents a “broader range of symptoms” compared to earlier variants.
Speaking to SFGATE, he said: “There’s a little bit more sore throats with some people. Particularly in those who are older, who didn’t get vaccinated last year.
“It’s more transmissible, so we expect that a lot of people will get it. Particularly with kids going back to school – a sniffle is likely going to be Covid.”
