A new Covid variant, known as Stratus, is spreading quickly and showing a symptom that sets it apart from earlier strains. The variant, which has two forms labeled XFG and XFG.3, was first detected in January. By June, the World Health Organization (WHO) placed XFG “under monitoring” because of its “increasing proportions globally.”
On September 3, the UK Health Security Agency reported a 7.1 percent rise in coronavirus cases across England compared to the previous week. It remains unclear how many of those infections are linked to the XFG strain. Meanwhile, New York health officials are responding to the spread of the Stratus variant as cases grow across the city.
Ireland has also been affected, with health authorities confirming 425 new infections in the first week of September. Most of those cases are believed to be connected to the XFG variant. COVID-19 infections generally mimic the flu, with symptoms such as fever, cough, sneezing, or a runny nose.
Cases can vary from mild to severe. But doctors now warn that the most common early sign of Stratus is a hoarse or raspy voice, which often develops before other symptoms and can be overlooked. Alongside the unusual vocal change, patients are also reporting sore throats, blocked noses, digestive problems, and fatigue.
Dr. Nye explained to the Mirror: “In most ways, it’s almost identical. However, people with this version tend to get very sore throats and a hoarse voice, compared with the other more general symptoms like cough, temperature, and aches.
“Illnesses always see spikes as children go back to school, as close contact and often lower personal hygiene levels mix.” He also emphasized the increased risk of illness with Stratus. “This version is more likely to make you sick, however, as they appear to be able to avoid your immune system even if you’ve had it before.
[This] makes prior vaccines less useful, which makes regular vaccination against the latest coronavirus even more important. Think of it like updating your phone to get the best possible experience.”
Infectious disease expert Dr. Peter Chin-Hong of the University of California, San Francisco, echoed the concern. He told SFGATE: “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.”
