Urgent holiday warning over new Covid variant that's ‘more infectious' as cases surge in popular hotspots

HEALTH authorities in popular holiday hotspots have issued warnings over a new Covid variant that's feared to be more infectious.
Travellers were urged to don masks and wash their hands as the new variant drives up cases.

The strain - called NB.1.8.1 - has been spotted in spots popular for British travellers, such as Egypt, the Maldives and Thailand.
It's also seen a rapid rise in Ireland in recent weeks and has been found in the US, Australia and the UK.
Health authorities in Thailand issued a warning about the variant, after recording Covid 257,280 cases and 52 deaths.
The country's capital Bangkok is seeing the worst of the outbreak, as well as the Chonburi Province.
Deputy government spokesperson Anukool Pruksanusak said international travel and the oncoming rainy season, could accelerate the outbreaks and the Ministry of Public Health will monitor the situation closely.
He urged people to "limit activities that increase the risk of infection, wash their hands regularly, wear masks in crowded places, get booster vaccinations when due, and seek medical attention promptly if experiencing symptoms".
It comes after the World Health Organisation (WHO) issued a warning over NB.1.8.1, designating it as a "variant under monitoring" due to its global spread and key mutations.
'Despite a concurrent increase in cases and hospitalisations in some countries where NB.1.8.1 is widespread, current data do not indicate that this variant leads to more severe illness than other variants in circulation,' the WHO said.
But while it may not be particularly severe, may infect people more easily than previous variants, with some evidence suggesting that the variant binds more tightly to human cells.
"Data indicates that NB.1.8.1 does not lead to more severe illness compared to previous variants, although it appears to have a growth advantage, suggesting it may spread more easily," Subhash Verma, a professor of microbiology and immunology at the University of Nevada, Reno School of Medicine, told CBS News last week.
"In other words, it is more transmissible."

Highest number of abortions ever recorded in Jersey in 2024

More abortions took place in Jersey in 2024 than at any time since 2002, a report has Abortions Report found about 280 pregnancies were terminated in 2024 - up from 260 in 2023, and compared with 210 in highest ever number of terminations was recorded among women aged between 25 and 29, the report also found Jersey's abortion ratio was the highest on record and above the EU average, with 390 terminations per 1,000 live births. 'Notably higher' The Public Health annual report said the abortion ratio was the highest reported in the past 25 said the rise was driven "not only by small year-on-year increases in the number of abortions being conducted but also by a significant reduction in the number of live births in recent years".The report said Jersey's abortion ratio of 390 per 1,000 was "notably higher" than many European countries with the EU average being 199 and Great Britain added this may reflect improved access to abortion care and a broader shift in reproductive report showed an increase in the abortion rate from 9.7 per 1,000 in 2020 to 14.9 in also found the proportion of abortions performed before 10 weeks' gestation was 93% in 2024 which it said indicated better early pregnancy recognition and access to services.

Walking 100 minutes per day may help lower risk of chronic back pain

For many people, low back pain is chronic, meaning it is constant for at least three are several risk factors for chronic low back pain, such as not getting enough physical activity. A new study found that increasing the length of time and intensity of one's walks may help lower the risk of experiencing chronic low back to the World Health Organization (WHO), about 619 million people around the world were living with low back pain in 2020. This number is expected to hit 843 million by 2050. For many people, their low back pain is chronic, meaning it is constant for at least three months. And the pain is moderate to intense, affecting their daily lives. There are a number of risk factors for chronic low back pain. Some are not modifiable, such as age, genetics, and underlying medical conditions such as arthritis, spinal infections, spinal stenosis, osteoporosis, and fibromyalgia. However, several risk factors are modifiable, including obesity, improving lifting techniques, smoking, stress, and a sedentary lifestyle.'Low back pain is the leading cause of disability worldwide and accounts for the highest healthcare spending in the U.S.,' Rayane Haddadj, MS, a PhD candidate in the Department of Public Health and Nursing at the Norwegian University of Science and Technology in Norway, told Medical News Today. 'Identifying modifiable risk factors that can be targeted and easily implemented through public health policy and interventions is therefore of great importance.'Haddadj is the first author of a new study recently published in the journal JAMA Network Open that says increasing the length of time you walk, and its intensity, may help lower your risk for chronic low back pain. Walking 100+ minutes per day lowers low back pain riskFor this study, researchers analyzed medical data from more than 11,000 adult participants with an average age of about 55 from the Trøndelag Health (HUNT) Study in Norway, which ran from 2017 to 2019 with a follow-up in 2021 to 2023. At the start of the HUNT study, study participants did not have chronic low back pain. Researchers focused on the daily minutes each participant walked and their walking intensity, or how quickly they walked, which is calculated by using the metabolic equivalent of task (MET) per the study's conclusion, Haddadj and his team found that participants walking for more than 100 minutes per day were associated with a 23% lower risk of chronic low back pain, compared to those who walked less than 78 minutes per day.78 vs. 100 minutes a day'Our study shows that higher daily walking volume lowers the risk of developing chronic low back pain. The relationship was dose-dependent — meaning the more people walked, the lower their risk — up to about 100 minutes per day, after which the benefit leveled off. Even small increases in daily walking were associated with a decreased risk of chronic low back pain.' — Rayane Haddadj, MSWalking intensity also linked to lower pain riskAdditionally, researchers discovered that walking intensity was also associated with the risk of chronic low back pain, but to a lesser degree than walking volume. 'Our results suggest that a higher average walking intensity is associated with lower risk of chronic low back pain,' Haddadj said. 'However, the association was less pronounced than for walking volume. Further research, including a more robust assessment of walking intensity, could enhance our understanding of its association with the risk of chronic low back pain.''Our results reinforce a growing body of evidence showing that physical activity is essential for long-term health. Even small increases in daily activity can make a difference. Or as the World Health Organization puts it 'every move counts towards a better health'.'— Rayane Haddadj, MS'Walking is a simple, low cost, and accessible activity that can be promoted widely to reduce the burden of low back pain,' Haddadj added. 'Walking more could therefore be a simple yet powerful way to reduce risk of chronic low back pain and other diseases. Future studies investigating parameters such as timing and context of walking could enhance our understanding of the association between walking and risk of chronic low back pain.' Walking more may not always prevent back painMNT spoke with Neel Anand, MD, MCh Orth, a board certified orthopedic spine surgeon and director of the Cedars-Sinai Spine Center in Los Angeles, about this study. Anand commented that while he agrees with the study's findings that activity is better than no activity, he does not agree with the idea that if you walk, you will lower your risk for chronic back pain. 'Walking does not prevent back pain. Walking helps you get better because activity will help back pain always — it actually does. If you have chronic back pain, activity and walking actually makes it feel better than remaining stationary.' — Neel Anand, MD, MCh Orth'But the idea that you walk, you're not going to get back pain, makes no sense at all — that idea is not logical,' Anand continued. 'Back pain is a degenerative disorder. Yes, a couch potato has more chances of getting back pain than a person who's more active — that is correct. But to take that a step further and say, just because you walk, you're not going to get back pain is too far a reach. In my opinion, that's too far a conclusion to make.'

A chartered physiotherapist shares three exercises that can ‘help reduce lower back pain'

Such is the prevalence of lower back pain that, in 2023, the World Health Organisation (WHO) released guidelines for 'non-surgical management' of the condition. An accompanying report states that lower back pain affected 619 million people globally in 2020, with that figure only expected to grow due to 'population expansion and ageing '. About 90 per cent of cases are non-specific – 'it isn't possible to identify a specific disease or structural reason to explain the pain'. According to the report, the major risk factors for non-specific lower back pain are low physical activity levels, obesity, smoking and high physical stress at work. As a result, 'physical therapies to improve muscle strength and ability to move', as well as 'lifestyle changes including more physical activity, healthy diet and good sleep habits', are front and centre among WHO's suggested treatments. How to use movement to manage lower back pain For many people, varied movement can be beneficial for easing lower back pain if approached in an appropriate, gradual and progressive way. After all, the body adheres to the SAID (specific adaptation to imposed demands) principle, so if pain-free movement of the spine is the goal, slowly reintroducing movement in this area is the obvious way to achieve it. Likewise, strengthening the surrounding muscles can help you build a strong base of support and stability for your spine. But what sort of movements can we use to achieve this? Below, chartered physiotherapist and Physique ambassador Tash Gale shares three exercises which 'can be helpful to reduce lower back pain'. Between them, they aim to mobilise the spine, reduce stiffness in the lower back and hips, and build core stability. However, she adds: 'Exercises chosen for back pain should be specifically chosen for an individual for their needs and the exercise should be tailored to the individual.' A physiotherapist's three exercises for reducing lower back pain Exercise one: Cat/cow stretch Sets: 3 Repetitions: 5-10 Start in a tabletop position, on your hands and knees with your arms straight, knees at a right angle, hands under your shoulders and knees under your hips. Inhale and lift your head and tailbone to arch your back. This is the 'cow' portion of the exercise. Exhale and tuck your chin and pelvis to round your spine. This is the 'cat' portion of the exercise. Benefits 'This move helps improve mobility and flexibility in the spine, gently mobilising the back and abdominal muscles to reduce tension and encourage natural spine mobilisation,' Gale explains. Exercise two: Knee rolls Sets: 3 Repetitions: 5-10 each side Lie on your back with your knees bent and your feet flat on the floor. Extend your arms out to your sides in a T-shape for support. Keep your shoulders flat on the ground throughout. Slowly drop both knees to one side, rotating through your spine and hips. Hold this position for five to 10 seconds, lift your knees back up to return to the starting position, then drop them to the other side. Benefits 'Knee rolls can help reduce stiffness in the lower back and hips,' says Gale. 'Engage the core muscles gently to support spinal control and improve spinal rotation and flexibility. It also promotes relaxation and stress relief through rhythmic movement.' Lie on your back on a yoga mat with your arms extended towards the ceiling. Engage your core by gently tightening your belly button down towards your spine, flatten your back against the floor and find engagement through your pelvic floor. Keeping your core engaged, lift your legs so your thighs are vertical and your knees are bent at a right angle. Slowly lower your right arm and extend your left leg towards the floor, keeping your back flat. Return to the starting position, then repeat with the opposite arm and leg. 'If your lower back lifts off the floor, reduce the range of motion [how far you lower your arms and legs] until your core is stronger,' Gale advises. Benefits 'This exercise helps to build core stability without stressing the spine,' Gale says. 'It encourages the correct movement patterns between the limbs and core, strengthens the deep abdominal muscles that support your lower back, and also helps improve coordination and neuromuscular control, reducing your risk of injury.'
