Rapidly spreading COVID variant triggers fresh warnings — these are the symptoms doctors urge you to track
A
new COVID variant
called NB.1.8.1 is spreading fast in the world. It was first found in China in January 2025. Now, it makes up 10% of all COVID samples globally, which is a big jump from 2.5% four weeks ago, as per reports.
The CDC said they're in touch with other countries about this variant. So far, only 20 cases have been found in the US, so it's not on the CDC COVID tracker yet. Doctors say this new variant causes similar symptoms to the older ones.
The main signs are a dry cough that stays for long, blocked or runny nose, and feeling very tired. You may also get fever, chills, sore throat, and pain in your body. Most people can still do their normal things, but they'll feel more tired than usual, as per HuffPost report.

There's no proof that NB.1.8.1 causes worse sickness or more people going to the hospital or dying. It has some new mutations on the spike protein that may help it spread faster and avoid the immune system. That means your body might not stop the virus as well as before, as per WHO.
Scientists think the vaccines will still protect you from serious illness. NB.1.8.1 comes from the Omicron JN.1 family, which the 2024-2025 vaccines are made to fight. Vaccines might not fully stop infection, but they still help prevent serious problems.
Live Events
If you're older, have health problems, or take immune-lowering medicines, you should get vaccinated if it's been over 6 months since your last dose. If you're young and healthy, you probably don't need another shot right now, as per the HuffPost report.
Most people can get better by just resting at home and drinking lots of fluids. If you have fever or body pain, you can take acetaminophen or ibuprofen. Normally, you'll feel better in about a week.
If you are older or have a weak immune system, talk to a doctor. Doctors may give you antiviral pills like Paxlovid or Molnupiravir. These medicines work best within 5 days after symptoms start.
Go to the hospital if you have chest pain, can't wake up or stay awake, feel confused or dizzy. The biggest red flag is trouble breathing , get help immediately if this happens, as per the HuffPost report.

Vitamin D supplements and their link with ageing: 5 unbelievable facts
Vitamin D, crucial for bone health and immunity, may also combat aging. A study revealed that vitamin D supplements help maintain telomere length, potentially delaying biological aging by nearly three years. Furthermore, it supports cardiovascular health, improves mood, and aids in weight management, highlighting its multifaceted benefits for overall well-being. Soak in the sunshine every morning. That daily dose of vitamin D can do wonders for your health. Vitamin D, also known as the 'sunshine vitamin', plays a critical role in bone health, immune function, and overall well-being. Recent research also suggests that it may help reverse age! A recent study led by researchers at Mass General Brigham and the Medical College of Georgia found that vitamin D supplements show signs of protection against biological aging. The findings are published in The American Journal of Clinical Nutrition . What is vitamin D Vitamin D is a fat-soluble nutrient essential for maintaining healthy bones, supporting immune function, and promoting overall well-being. It is produced by the skin when exposed to sunlight and can also be consumed from animal-based foods such as salmon, cod, and egg yolks. Vitamin D and ageing The recent controlled trial revealed that vitamin D supplementation helps to maintain telomeres, the protective caps found at the ends of chromosomes that shorten during aging and are linked to the development of certain diseases. 'VITAL is the first large-scale and long-term randomized trial to show that vitamin D supplements protect telomeres and preserve telomere length. This is of particular interest because VITAL had also shown benefits of vitamin D in reducing inflammation and lowering risks of selected chronic diseases of aging, such as advanced cancer and autoimmune disease,' co-author JoAnn Manson, MD, principal investigator and chief of the Division of Preventive Medicine at Brigham and Women's Hospital, said in a release. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo Easy ways to increase your Vitamin D intake The study followed over 1,000 participants for four years and found that those who took vitamin D3 supplementation daily had slowed the process of telomere shortening. This means it delayed biological aging by nearly three years. The shortening of the telomeres is also linked to increased risk of many age-related diseases. 'Targeted vitamin D supplementation may be a promising strategy to counter a biological aging process, although further research is warranted,' the researchers noted. Vitamin D and immunity Studies have also found that a low level of vitamin D increased the risk of infections and autoimmune diseases, such as rheumatoid arthritis, type 1 diabetes, and inflammatory bowel disease. A 2020 study found that vitamin D can improve immune health and decrease the susceptibility to autoimmune diseases. Vitamin D and cardiovascular health Vitamin D plays a crucial role in fighting disease. Low levels of vitamin D are linked to increased risk of cardiovascular diseases, including hypertension, coronary artery disease, ischemic heart disease, heart failure, stroke, and type 2 diabetes. A systemic analysis and meta-analysis conducted by scientists from institutions across China and the United States in 2024 found that targeted vitamin D supplementation can improve cardiometabolic health. The analysis found that vitamin D supplementation was associated with favorable effects on various cardiometabolic risk factors, including reductions in systolic and diastolic blood pressure, total cholesterol, fasting blood glucose, hemoglobin A1C, and fasting blood insulin. Vitamin D and mood Studies have shown that vitamin D plays a key role in decreasing the risk of depression and also regulating mood. A 2020 systematic review and meta-analysis of 7,534 people found that vitamin D supplementation can reduce negative emotions. Researchers noted that patients with major depressive disorder and individuals with vitamin D deficiency are most likely to benefit from supplementation. Vitamin D and weight loss Vitamin D has also shown promise in weight management. A 2018 study looked at the effects of vitamin D supplementation on weight Loss, glycemic indices, and lipid profile in obese and overweight Women. After 6 weeks of supplementation in obese and overweight women aged 20–40 years, the researchers found a reduction in the mean of BMI, weight, and waist circumference.

Iran 'strongly' condemns US veto of UN Gaza ceasefire resolution
Displaced Palestinians return to retrieve their belongings from their homes in the area where the Israeli army operated in the northern Gaza Strip (AP) TEHRAN: Iran on Thursday denounced the United States on Thursday for vetoing a United Nations Security Council resolution that called for an immediate ceasefire and full humanitarian access in Gaza. Foreign ministry spokesman Esmaeil Baqaei said in a statement that the US move to block the resolution, which was supported by 14 of the 15 members of the council, demonstrated "the country's complicity in the crimes of the Zionist regime (Israel) and strongly condemned it". The draft resolution had demanded "an immediate, unconditional and permanent ceasefire in Gaza respected by all parties" and the unconditional release of hostages held by Hamas in the war-torn Gaza Strip. It also called for the lifting of all restrictions on humanitarian aid entering the territory. Baqaei said the veto "is not only an explicit affront by the US government to the will of the international community ... but also a sign of the moral decline of American decision-makers" and evidence of Washington's complicity in Israel's killing of Palestinians. Washington's envoy to the UN, Dorothy Shea, said on Wednesday that passing the resolution "would undermine diplomatic efforts to reach a ceasefire that reflects the realities on the ground and emboldens Hamas," which is backed by Iran. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo Tehran, which does not recognise Israel, has framed the Palestinian cause as a central tenet of its foreign policy since the 1979 Islamic Revolution.

Lab Grown Diamonds set to lose 4Cs certification; will buyers really bother?
Would you buy a diamond if it did not have the 4Cs certification? The natural diamond industry, crumbling under the onslaught of technology-driven Lab Grown Diamonds (LGDs), is certainly hoping you wouldn' a desperate bid to deter consumers from buying tech-driven diamonds, which have flooded the market at a third of the price of natural diamonds, the Gemological Institute of America, one of the world's leading diamond grading agencies, has announced it will no longer use its internationally recognised 4Cs grading system for laboratory-grown beginning later this year, lab-grown diamonds submitted to the GIA will receive simplified descriptors—categorised broadly as either 'premium' or 'standard', or no grade at all if the quality is value of diamonds is decided on the basis of the 4 Cs—colour, clarity, cut and carat weight. There are several grading agencies the world over, of which the GIA, International Gemological Institute (IGI) and Hoge Raad voor Diamant (HRD) are the most respected. The latter two particularly hold weight in Europe and Asia while the GIA has global acceptance. The decision to discontinue the grading for LGDs is meant to emphasise their difference from natural diamonds. Henry Smith, head of sales at the Institute of Diamonds, a part of the De Beers Group, said the GIA's move is more than a simple nomenclature change. 'The GIA's adoption of a distinct grading framework for LGDs is a significant advancement in safeguarding the gemological integrity of the diamond industry. Natural diamonds are rare geological treasures formed under immense heat and pressure over billions of years. Applying the same 4Cs grading system to lab-grown synthetics, which are produced in a matter of weeks in controlled environments, can lead to misinterpretation of value and rarity. The GIA's move supports a more accurate and transparent classification system that aligns with the scientific and commercial realities of the two products,' explained the past two years, the global natural diamond market has seen an unprecedented 30 per cent correction in prices, driven by slowdown in sales, partially due to Covid-triggered economic slump. There is a glut of inventory while the demand is sluggish as new and low to medium-end buyers are shifting to natural diamond industry has been flummoxed about how to respond to this disruptor technology, which is threatening to uproot the centuries-old, billion dollars' worth of diamond mining, trading, polishing and uber premium jewellery sales industry. As a consequence, major diamond polishers and exporters in the Surat hub have reduced by more than half the wages and work hours of hundreds of thousands of artisans. This has created a socio-economic humanitarian crisis in Surat, where nine of every 10 diamonds sold the world over are Bhansali, chairman of the Gem and Jewellery Export Promotion Council (GJEPC), India's apex jewellery trade body, said the GIA's decision to use descriptive terms instead of the 4Cs grading for LGDs is an important evolution in diamond classification. 'This will help eliminate confusion by clearly distinguishing how lab-grown diamonds are assessed, separate from the standards developed for natural diamonds. For India, as a leading hub for both natural and lab-grown diamonds, this change brings much-needed clarity and balance to the marketplace—allowing both categories to grow with greater transparency, integrity and consumer confidence,' he producers in India are disappointed but not particularly perturbed by the GIA's decision. 'We will approach other grading agencies—for instance, IGI—to certify our product and take our business there. For the domestic market, Indian grading agencies such as the Gemological Institute of India (GII) will gain traction,' said Shashikant Shah, chairman of the LGD Council of India. He added that this move exposes the panic seeping into the natural diamond industry as they are desperate to reverse the global slide in prices of natural diamonds and clear their inventory worth hundreds of crores of to India Today MagazineTrending Reel
