New Covid Stratus variant becomes dominant in UK with unique symptom
In just a month, Stratus infections have skyrocketed due to its capacity to reinfect those who've previously contracted Covid or have been vaccinated.
According to the UK Health Security Agency (UKHSA), Stratus is now the leading Covid variant in England, jumping from 10% of cases in May to 40% by mid-June. Notably, two versions of Stratus are in circulation: XFG and XFG. 3.
Speaking to Cosmopolitan UK, Dr Kaywaan Khan, a Harley Street GP and founder of Hannah London Clinic, noted: "Unlike other variants, Stratus has certain mutations in the spike protein which could help it evade antibodies developed from prior infections or vaccinations."
Dr Khan also said that Stratus doesn't seem to make people 'more ill' than earlier strains but highlighted a unique symptom: "One of the most noticeable symptoms of the Stratus variant is hoarseness, which includes a scratchy or raspy voice.", reports Wales Online. Dr Khan said in general, the symptoms of Stratus tend to be 'mild to moderate'
Dr Khan said: "If you test positive, Stratus is highly contagious, and it is advised to stay home and isolate to avoid spreading to others."
Professor Lawrence Young, a virologist at Warwick University, told MailOnline: "The increased competitiveness of XFG and XFG.3 is likely due to new spike mutations which make these variants more able to evade the immune response.
"Given that immunity to Covid is waning in the population due to a decline in uptake of the spring booster jab and the reduction of Covid infections in recent months, more people will be susceptible to infection with XFG and XFG.3. This could lead to a new wave of infection but it's difficult to predict the extent of this wave."
The World Health Organisation has designated Stratis a 'variant under monitoring', meaning it is keeping a close eye on the spread of the strain. It accounts for 22% of all cases around the world.
The spread of Stratus follows quickly on the back of another strain - Nimbus - which was reported to give people a very sore throat. That now accounts for 17% of all tested cases in the UK.
Dr Michael Gregory, regional medical Director for NHS England said: "The variant looks to be spreading rapidly within communities, with top symptoms being a 'razor blade' sore throat and swollen neck glands."

60-year-old Glasgow man to take on Forth Bridge abseil
Charles Smith from Glasgow will take on the descent from the top of the Forth Bridge on Sunday, September 28, to raise funds for Chest Heart & Stroke Scotland (CHSS). He said: "I had intended to do this a few years ago and raise funds for cystic fibrosis as a couple of my nieces have the condition but unfortunately Covid-19 came along and stopped me doing it. "So I ended up doing a parachute jump after a while instead. "I looked for an opportunity to do the abseil again and I noticed it on the CHSS website. "My father, James, passed away with a heart and stroke condition and a few of my friends have had frights with heart attacks recently and so has my mother, Margaret. "It seemed quite a relevant charity to support". Read more: Meet the 63-year-old 'Summer Santa' zip sliding along the Clyde for cancer care The Forth Bridge abseil, organised by CHSS in partnership with Network Rail and Balfour Beatty, is one of Scotland's most well-known fundraising events. Previous events held in June and October raised a combined total of more than £390,000 for all participating charities. Speaking about the upcoming abseil, Charles admitted that despite having previous experience he still feels apprehensive about the event. He said: "I've done a wee bit before but I will still be nervous hanging over the edge. "I do like doing adventurous things though. "I was up the top of the Forth Road Bridge for its 60th anniversary so I'm making my way across the bridges. "It was a cracking experience and I'm looking forward to this one as well."

Stephanie Wilks, community, events and corporate fundraiser at CHSS, said: "We thank Charles for his participation in the 2025 Forth Bridge Abseil and wish him all the best in his fundraising and on the day. "Every pound raised through fundraising helps CHSS to support the one in five people in Scotland who are living with chest, heart and stroke conditions and Long Covid to live life to the full. 'It helps us to provide advice and support through our free Advice Line service, stroke nurses, online health information, support groups, supported self management courses and much more.'

Amir Kol, associate professor in the Department of Pathology, Microbiology and Immunology at the UC Davis School of Veterinary Medicine, said: 'It's important to understand that many pets suffer from diseases that are similar to human diseases.

Advertisement Hide Ad Advertisement Hide Ad Most people who have Covid will feel better in a few days or weeks and make a full recovery after 12 weeks. However, for some people, Covid symptoms continue and can have a big impact on their lives. What are the signs and symptoms of Long Covid? Long Covid can affect people of all ages; the most common symptoms can include extreme tiredness, feeling short of breath, muscle aches, difficulty concentrating, and joint pain. According to the NHS, the most common symptoms of long COVID are: extreme tiredness (fatigue) feeling short of breath problems with your memory and concentration ("brain fog") heart palpitations dizziness joint pain and muscle aches Other persisting symptoms can include: Advertisement Hide Ad Advertisement Hide Ad loss of smell chest pain or tightness difficulty sleeping (insomnia) pins and needles depression and anxiety tinnitus, earaches feeling sick, diarrhoea, stomach aches, loss of appetite cough, headaches, sore throat, changes to sense of smell or taste rashes How long does Long Covid last? For most people, the symptoms of Covid will get better within days to weeks; however, for others, they can persist. Long Covid symptoms can continue for weeks, months, or even years after the initial Covid infection. What are the treatment options for Long Covid? The NHS offers treatment centres for people who think they may have Long Covid. These multidisciplinary clinics offer physical, cognitive, and psychological assessments, diagnostic tests, and management or appropriate onward referral for rehabilitation, and other support. If you think you may be experiencing Long Covid, talk to your GP to find out if you meet the criteria and can be referred to a Long Covid Clinic. How can cats help with Long Covid? Scientists at the University of California, Davis, believe that cats may be able to offer us insight on how to help patients with Long Covid. Feline infectious peritonitis, or FIP, is a serious disease found in cats caused by Coronavirus. Advertisement Hide Ad Advertisement Hide Ad Up until recently, FIP was fatal in cats, but thanks to a new antiviral agent, many cats now recover. Scientists have found that some of the cats who recover from FIP still have enlarged lymph nodes, indicating that their immune systems are overworking, which is something that people with Long Covid can experience. They found that using antivirals along with infusions of MSCs helped some of the cats' immune systems recover compared to those that had antivirals alone. Kol said: 'Our findings support the idea that FIP in cats is a useful model for studying long-term immune problems after a viral infection — something that also happens in some people after illnesses like COVID-19. It shows that MSC therapy might not only reduce short-term inflammation but help bring the immune system back into lasting balance.' The findings could help scientists understand if a similar approach could help with viruses in humans, such as Long Covid. The last thing you'd want this summer is to catch Covid on your holiday.
