Covid-19 variant ‘Nimbus' with ‘razor blade throat' symptom spreads in California – should you worry?
A new Covid-19 variant – NB.1.8.1 or 'Nimbus' – may be driving a recent rise in cases in some parts of the world. The rise is cases in primarily seen in eastern Mediterranean, Southeast Asia and western Pacific regions, the World Health Organization said on May 28. The new variant had reached nearly 11 per cent of sequenced samples reported globally in mid-May, an AP report said on Wednesday.
Airport screening in the United States detected the new variant in travelers arriving from those regions to destinations in California, Washington state, Virginia and New York.
You aren't likely to get sicker from this variant than others. The WHO said some western Pacific countries have reported increases in Covid cases and hospitalisations, but there's nothing so far to suggest that the disease associated with the new variant is more severe compared to other variants, the report added.
The variant has earned a new nickname – 'razor blade throat' Covid. That's because the variant may cause painful sore throats. The symptom has been identified by doctors in the United Kingdom, India and elsewhere, according to various media outlets.
According to the AP report, other Covid-19 symptoms of any variant include fever, chills, cough, shortness of breath or loss of taste or smell. Experts say there isn't major cause for concern with the Nimbus variant.
The WHO has designated Nimbus as a 'variant under monitoring' and considers the public health risk low at the global level. Current vaccines are expected to remain effective.
A US government scientist who oversees the team responsible for collecting data on Covid-19 and RSV hospitalisations used to shape national vaccine policy has resigned, citing concerns over how such data would be used by the Trump administration.
The scientist, Dr Fiona Havers, told colleagues at the Centers for Disease Control and Prevention on Monday that she no longer had confidence that the Covid and RSV data would be used "objectively or evaluated with appropriate scientific rigor to make evidence-based vaccine policy decisions," according to an email seen by Reuters.
Havers, leader of the RESP-NET Hospitalization Surveillance Team, did not respond to requests for comment.
Her resignation follows moves by Health Secretary Robert Kennedy Jr. to abruptly fire all 17 members of the CDC's independent vaccine advisory panel and drop a recommendation for administering Covid shots to healthy children and pregnant women.
Kennedy, who has long sown doubt about the safety and efficacy of vaccines, replaced the advisory board with eight members of his own choosing, some of whom have histories of objecting to Covid shots or vaccines in general.

Yoga Day 2025: Shavasana to baddha konasana, 8 best asanas for PCOS
Yoga Day 2025: Polycystic ovary syndrome (PCOS) – a chronic hormonal condition that can result in irregular periods, severe pain and even weight gain – affects up to 6–13 percent women of reproductive age and up to 70 percent of affected women remain undiagnosed worldwide, according to World Health Organization. But did you know yoga may be able to help manage PCOS symptoms? Also read | Gynaecologist explains how your menstrual health can reveal early signs of PCOS: 'Heavy bleeding isn't always normal' Yoga Day 2025: Bow pose sends a gentle wave of fresh blood to your head and pelvis, easing tightness in the tummy while providing a mild internal massage (Freepik) In an interview with HT Lifestyle, Samiksha Shetty, founder of Rising Loka, said that instead of silently suffering from PCOS, women should be encouraged to make lifestyle changes that could support their health. 'A consistent workout routine which includes yoga asanas, pranayama and meditation, helps balance women's hormones, insulin resistance and blood sugar levels,' she said. Samiksha added, 'Now, you might say any workout can do that. But yoga works on a cellular level as well. Yoga goes way beyond its physical benefits—it helps reduce stress and cortisol levels, which is very important for hormonal health. Yoga can help relieve anxiety, balance hormones, improve menstrual cycles, and rev up your body's metabolism. Also, relaxation is the key to fighting PCOS.' She suggested that a daily calming yoga practice with a focus on stress reduction is a good place to start. However, it is important to understand our body's ability to practice certain asana/yoga flows, she said, and added: 'Not all yoga practices are stress-reducing. Some vigorous practices may stress the body and add to the load on the adrenal glands.' Samiksha added that a regular yoga practice makes us more aware and helps us focus on our breathing patterns. 'Breathing is something so natural to us that we often take it for granted. The three pranayama practices that are beneficial for PCOS are alternate nostril breathing (a subtle energy clearing technique), bhramari pranayama (a humming bee breathing technique), and kapalbhathi pranayama (a breath of fire).' Are there any specific yoga poses that may help with PCOS? Here's what Samiksha suggested: Despite its apparent simplicity, shavasana is one of the most crucial yoga poses. (Freepik) 1. Vyaghra shwasa (tiger breathing) She said, 'You probably know it better as the cat-cow stretch. Done with steady, deep breaths, it eases tightness in your spine, back, and neck, adds movement to those areas, and leaves the whole body feeling calmer.' 2. Malasana (garland pose) aka wide squat pose 'At first glance, this sturdy squat looks easy, yet the comforts of modern life have made it surprisingly tough for many of us. If your heels stubbornly lift, slide a rolled towel, mat or block under them and keep breathing,' she added. 3. Parivrtta trikonasana stretch (revolved triangle breathing) According to Samiksha, gentle twists like this one 'massage the waist, tone the belly and give the reproductive organs a nice boost'. 4. Baddha konasana (bound angle or butterfly pose) Samiksha said, 'Also called 'the butterfly', this seated pose is cherished by women dealing with PCOS and eases cramps and backache during periods and pregnancy. Beyond that it loosens stiff ankles, knees and hips, opens the joint, and finally sparks a much-needed emotional release.' 5. Dhanurasana (bow pose) 'Bow pose sends a gentle wave of fresh blood to your head and pelvis, easing tightness in the tummy while providing a mild internal massage. When done regularly, it builds endurance in the reproductive organs and offers relief from stubborn indigestion and constipation alike,' she added. 6. Setu Bandhasana (bridge pose) According to Samiksha, 'Bridge pose works wonders for achy lower backs, sciatica, and general stiffness in ankles, hips, backs, thighs, and shoulder blades. It also supports reproductive health, broadens lung capacity, and can soothe discomfort during menstruation or throughout pregnancy while firming up the muscles along your spine.' 7. Balasana (pose of the child) She added, 'The child's pose, which encourages relaxation by soothing the central nervous system, is one of the most vital yoga poses for PCOs. In addition, it normalises blood flow throughout the body and reduces PMS symptoms, lower back tension, and menstrual cramps.' 8. Shavasana (pose of the corpse) 'Despite its apparent simplicity, shavasana is one of the most crucial yoga poses. Since we do not perceive the benefits of this pose, many of us avoid it. Your nervous system is balanced by this pose. It facilitates the body's transition into a relaxed and peaceful state. It aids in body cooling and the removal of emotional blockages,' she concluded.

Mercury poisoning in Perus Amazon threatens health disaster
Illegal gold mines pollute Peru's Loreto region Nearly 80% of people have mercury unsafe levels Pregnant women and children most at risk LIMA, June 20 (Thomson Reuters Foundation) - Indigenous and riverine communities in the Loreto region of the Peruvian Amazon have "chronic exposure" to mercury, according to a new study by the Center for Amazonian Scientific Innovation at Wake Forest University in the United States. The test results released this month show nearly 80% of the people tested late last year had levels of mercury far above the safe limits in six communities on the banks of the Nanay and Pintuyacu rivers. "The majority of the population is contaminated," said Jairo Reategui Davila, the Apu, or leader, of San Antonio de Nanay, one of the tested communities. "We call on the authorities to take action on the matter because we are very concerned," he said. The results showed 37% of the 273 men, women and children tested had levels of mercury at more than 10 ppm (parts per million) in their hair, compared to just 3% under the 2.2 ppm 'safe' limit established by the World Health Organization (WHO). Gold prices have soared by nearly 50% in the last year, beating successive record highs, and encouraging a flourishing illegal gold mining trade that is damaging local nature and biodiversity, and raising significant health concerns. Illegal miners use mercury to extract gold particles from the river silt and then burn off the toxic metal, which turns to vapour and is absorbed by surrounding plants, soil and rivers, said Claudia Vega, head of the mercury program at CINCIA. Mercury poisoning is associated with several health issues, including cognitive impairment in adults and irreversible developmental delays and learning difficulties for children and babies in the womb. Gabriel Barría, regional coordinator for heavy metals for the local health authority, said it was "very regrettable that villagers were highly contaminated" and blamed the spread of illegal gold mining for the mercury levels in Amazon rivers. He said the health authority did not have the budget to carry out tests for mercury and had only tested 12 villagers on a recent health visit relying on blood and urine samples. CINCIA said tests revealed an average level was 8.41 ppm, exceeding the WHO limit by nearly four times. Given that illegal mining in Loreto is fairly recent, there are no comprehensive studies on its health impact on the local population yet. But the levels in these initial tests are already higher than those in the Peruvian Amazon region most impacted by illegal gold mining, Madre de Dios, where 2012 tests showed the majority of adults had average mercury levels of 2.7ppm. Luis Fernandez, executive director of CINCIA and Research Professor at Wake Forest University, said if illegal mining continued to spread in Loreto, then villagers with already high mercury levels might begin to approach those close to the worst recorded case of mercury contamination. This includes Minamata Bay, the renowned case in Japan in the 1950s, where children were born with congenital deformities and neurological disabilities caused by a chemical factory dumping mercury into the water supply for decades. Vega from CINCIA, who led the study, said the results showed worrying "background" levels of mercury in the Loreto riparian communities. She said it could not be fully determined if the mercury came from naturally occurring sources or human-caused activities like illegal gold mining, but it was mostly caused by the villagers' diet fish-based diet. However, "several studies agree that the entry of mining into a territory tends to significantly increase mercury levels in the environment", she said. The newly released study found that people were mainly exposed to methylmercury, a highly toxic form that accumulates in the body.
