New COVID strain 'Stratus': Experts warn of a strange symptom
Experts in the UK have warned of a new Covid variant called 'Stratus' that could drive a new wave of infections. Scientifically known as XFG, this strain is thought to be more infectious than the previous strains due to its mutations that help evade the immune system.
According to the data from the UK Health Security Agency (UKHSA), Stratus has now become the dominant COVID-19 strain in England, going from accounting for about 10% of all Covid cases in May to almost 40% of all cases in mid-June.
Stratus, which is a descendant of the super-virulent Omicron, is known as a Frankenstein or 'recombinant' strain, meaning it emerged when a person was infected with two Covid strains at once, which became a new hybrid variant.
Both strains of Stratus- the original XFG and the spin-off XFG.3 are 'rapidly spreading' said Professor Lawrence Young, a virologist at Warwick University to MailOnline.
"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," he added.

Can Stratus cause more severe illness?

According to Young, currently, there is no evidence that proves that Stratus causes more severe illness. He added that getting a Covid vaccine was 'very likely' to prevent severe illness and hospitalisation.
WHO (World Health Organization) declared the strain as a 'variant under monitoring' while assessing its overall risk as 'low' However, the organisation also pointed to the variant having a significant growth advantage when compared to other strains with it currently accounting for 22% of cases recorded worldwide.
What are the symptoms of the Stratus strain?

Most of the symptoms of Stratus are similar to the previous strains. According to the NHS, these symptoms include shortness of breath, loss or change to smell or taste, feeling tired or exhausted, high temperature or shivering, blocked or runny nose, aching body, continuous cough, sore throat, headache, diarrhoea, loss of appetite, and feeling sick.
However, according to Dr Kaywaan Khan, Harley Street GP and Founder of Hannah London Clinic, one of the most noticeable symptoms of the Stratus variant is hoarseness, which includes a scratchy or raspy voice.
The doctor added that the symptoms tend to be mild to moderate in general and if a person tests positive, they must stay at home and isolate as Stratus is highly contagious added the doctor in conversation with Cosmopolitan UK.

7 science-backed tips to boost heart and brain health
Prioritizing heart and brain health is crucial in today's demanding lifestyle. A balanced diet, regular exercise, and quitting tobacco are essential steps. Getting enough sleep, managing cholesterol and blood sugar, and keeping blood pressure in check are also vital for overall well-being and reducing the risk of chronic diseases. Did you know that your brain fires more messages than all the phones in the world combined? Similarly, your heart beats around 100,000 times a day, in order to keep you alive, sharp, and thriving. While taking care of heart and brain health is extremely important, we often tend to add pressure to it with today's lifestyle. From sedentary habits to poor dietary choices, our modern lifestyle often works against the very organs we rely on the most. What's the fix? Well, the trick is in the basics. Here are 7 science-backed tips to boost your heart and brain. Eat better A balanced and nutritious diet is important for both the heart and the brain. The Mediterranean diet, which is loaded with fruits, vegetables, whole grains, lean proteins, and healthy fats like olive oil, is heart-healthy. This diet reduces the risk of heart disease by up to 30%. Eating omega-3 fatty acids, found in fish like salmon, is known to support cognitive function. It is also important to limit processed foods, added sugars, and saturated fats to keep the arteries clear and brain cells sharp. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch vàng CFDs với sàn môi giới tin cậy IC Markets Tìm hiểu thêm Undo Stay active Regular exercise is crucial to strengthen the heart and improve brain health. Aim for at least 150 minutes of exercise a week. This could be moderate aerobic activity, like brisk walking or cycling. A 2025 study found that even small amounts of moderate to vigorous physical activity are associated with big reductions in dementia risk. Exercise does not really mean spending hours in the gym. Even small bursts of activity, like taking stairs or walking, can help. Quit tobacco Smoking does no favour for your heart or the brain. In fact, it's wreaking havoc on your health. Tobacco damages blood vessels and impairs brain function. Quitting tobacco lowers heart attack risk and also improves cerebral blood flow. Even vaping, which is often marketed as a safer option, still poses risks due to nicotine's impact on blood pressure. Vaping is a way for adults to stop smoking. It's not for non-smokers, especially children and young people, to try. Get a good night's sleep (Pic courtesy: iStock) A restful sleep is important for your overall well-being. Sleep is important for brain repair, as well as heart health. Aim for at least 7-9 hours nightly. A 2024 study found that poor sleep increases the risk of hypertension and cognitive decline. Maintain a consistent sleep schedule. Good sleep hygiene, such as limiting screen time before bed, avoiding coffee at least 2 or 3 hours before sleep, and creating a restful environment, can help. 'Pretty Little Baby' Singer Connie Francis Hospitalised, Family Gives Health Update Keep cholesterol in check When the cholesterol levels go up, it clogs the arteries, which raises the risk of a heart attack and stroke. It can also affect memory. Monitoring LDL, the bad cholesterol, is important. One can maintain healthy levels through diet, exercise, or medication if needed. You will be able to catch these early on with regular check-ups. Blood sugar levels matter too Elevated blood sugar levels can damage blood vessels and nerves. This can harm both the heart and the brain. Studies have found that stable glucose levels reduce cognitive decline risk in diabetics. Simple things like monitoring blood sugar, eating low-glycemic foods, and following medical advice can help. Keep blood pressure in check Hypertension, which is often called a silent killer, is one of the leading causes of chronic illness, such as heart disease, stroke, and kidney failure. It also increases the risk of dementia. Regular monitoring, stress management, and a low-sodium diet are important to regulate blood pressure.

BJP leader accuses CM of spreading fake news on Covid-19 vaccines
Bengaluru: BJP MP Lahar Singh Siroya on Friday accused Karnataka Chief Minister Siddaramaiah of spreading fake news with his recent remarks linking Covid-19 vaccines with a spate of heart attack deaths in the state's Hassan district, saying there is no vaccine against 'dissident' activities. The CM has suggested that the recent heart attack deaths in Hassan district may be linked to the vaccination drive. He also claimed the vaccines were 'hastily' approved. Taking a dig at Siddaramaiah, the BJP MP said that the Karnataka government has been speaking about tough legislation, including a seven-year jail term and fine, against the promotion and spread of fake news. 'At the rate at which Chief Minister Siddaramaiah has been speaking, I think someone will register the first complaint against him for spreading #fakenews on #Covid vaccines. The Union government has already clarified on this issue,' he said in a post on 'X'. According to him, the Congress' effort is to demoralise the scientific community, which saved millions of lives during the pandemic. 'I hope someone in the Congress cautions him (Siddaramaiah). Perhaps there is nobody left to caution him because nobody in his own High Command or locally think his government will survive for long. There is no vaccine against dissident activities,' Siroya said in the post.

Caution not anti-science, says CM as slugfest over vaccine heats up
A social media spat between chief minister Siddaramaiah and Biocon Executive chairperson Kiran Mazumdar-Shaw has brought renewed attention to the safety of COVID-19 vaccines and their possible long-term side effects. The exchange follows mounting concerns in Hassan district, where a spike in sudden heart-related deaths has raised public alarm. Caution not anti-science, says CM as slugfest over vaccine heats up The chief minister's initial remarks on July 1 questioned whether the deaths could be connected to the fast-tracked rollout of vaccines during the pandemic. While acknowledging that the vaccines were introduced under extraordinary global circumstances, Siddaramaiah suggested that the speed of approval may have overlooked long-term effects. 'It cannot be denied that the hasty approval and distribution of the COVID-19 vaccines to the public could also be a reason for these deaths,' he said in a post on the social media platform X, citing emerging global research linking vaccines to heart-related complications. To address public concerns, Siddaramaiah said his government had formed an expert committee led by Dr Ravindranath KS of Sri Jayadeva Institute of Cardiovascular Sciences and Research. The panel's mandate is to determine whether there is any scientific link between the vaccine rollout and the recent deaths in Hassan. In response, Shaw on Thursday challenged the chief minister's framing of the vaccine development process, calling it misleading and inaccurate. She said that India's vaccines were granted Emergency Use Authorisation (EUA) after meeting globally accepted safety and efficacy norms. 'To suggest that these vaccines were 'hastily' approved is factually incorrect and contributes to public misinformation,' she wrote, while also noting that side effects, though rare, did occur with any vaccine. In her follow-up post, Shaw said she agreed with the need for investigations into sudden deaths but reiterated that the regulatory process followed for vaccine approval met international standards. 'My response was that due process was followed as prescribed by WHO for safety and efficacy for Emergency Use Authorisation,' she wrote. 'Losing lives in a sudden manner is always tragic, and I am glad an investigation is being conducted in Hassan district.' By Friday, the discussion intensified as Siddaramaiah returned to the issue, stating that his role as chief minister obligated him to respond to the distress of families who had lost loved ones. 'When parents lose their young children or families lose breadwinners without warning, seeking clarity is not misinformation; it is an act of governance rooted in empathy,' he said. The chief minister further argued that questioning vaccine safety should not be equated with denialism or anti-science sentiment. He referred to studies published in journals such as Nature, Circulation, and the Journal of the American College of Cardiology, which have examined risks like myocarditis and cardiac arrest among younger populations post-vaccination. He also cited an admission by AstraZeneca about rare but serious side effects. 'Scientific caution is not anti-science,' Siddaramaiah said, adding that 'publicly funded stakeholders must acknowledge both the benefits and the potential risks without fear or favour.' He clarified that his use of the term 'hastily' was in reference to the emergency rollout timelines that global health agencies, including the WHO, had termed a 'calculated risk' during the height of the pandemic. 'Haste is not a sin when saving lives,' he said, 'but acknowledging potential unintended consequences is wisdom.' Meanwhile, the Union health ministry dismissed any connection between COVID-19 vaccines and the recent deaths. Referring to data from the Indian Council of Medical Research (ICMR) and the National Centre for Disease Control (NCDC), the ministry asserted that the vaccines were both safe and effective, with serious adverse reactions being extremely rare.
