What is behind the global spread of new Covid strain NB.1.8.1?
A new Covid variant, NB.1.8.1, derived from Omicron, is spreading globally, with a surge of cases reported in India and detections in Asian countries, the UK, the US, and Australia.
The WHO has classified NB.1.8.1 as a 'variant under monitoring' due to its potential impact on virus behaviour; by late April, it comprised 10.7 per cent of global sequences, up from 2.5 per cent a month prior.
Dr Naveed Asif, GP at The London General Practice, said the WHO assessed the additional risk to the global public as currently low.
Existing Covid-19 vaccines are considered effective in preventing severe disease, though it appears more transmissible than previous variants.
Common symptoms of the NB.1.8.1 variant include a severe sore throat, fatigue, mild cough, fever, muscle aches, and congestion; some patients have also reported gastrointestinal symptoms.

New Covid strain with 'unusual' symptoms identified as cases surge
New Covid strain with 'unusual' symptoms identified as cases surge The new Covid variant, labelled NB.1.8.1, is causing unusual gastrointestinal problems, health officials have warned The new strain of Covid is the result of two variants combining (Image: Getty Images/Westend61 ) Health authorities have issued an alert regarding a new strain of coronavirus after a surge in cases. Residents in Ireland are being advised to self-isolate for two days if they exhibit any Covid symptoms, as the new variant - which presents with unusual symptoms - is also linked to gastrointestinal issues. The variant, known as NB.1.8.1, has already been identified in the UK, US and Australia. Specialists emphasised that while previous strains have been associated with flu-like symptoms, NB. 1.8.1 can lead to gastrointestinal problems such as nausea, vomiting, diarrhoea and heartburn. Patients experiencing bloating, constipation and abdominal pain could also be suffering from Covid-19, reports the Mirror. The World Health Organization (WHO) has added the variant to its official watch list, suggesting it may be more transmissible than other strains. However, there's no evidence yet to suggest it leads to more severe illness. For our free daily briefing on the biggest issues facing the nation, sign up to the Wales Matters newsletter here . According to WHO, the strain first emerged in January and by late April it accounted for approximately 10.7% of global infections, a significant increase from just 2.5% a month earlier. The variant has also been identified in renowned holiday destinations such as Thailand, Egypt, and the Maldives. It has rapidly become the prevailing strain in some Asian regions, including China and Hong Kong. Article continues below Dr Lara Herrero, an Associate Professor and Virology Research Leader at Griffith University, shared details about the symptoms: "Common symptoms [of NB.1.8.1] include sore throat, fatigue, fever, mild cough, muscle aches and nasal congestion. Gastrointestinal symptoms may also occur in some cases."

Just how psychopathic are surgeons?
These are the people we trust to hold a sharpened knife above our bare bellies and press down until they see blood. We let them tinker with our hearts, brains and bowels while we lie unconscious beneath their gloved hands. Surgeons live in a world of terrifying margins, where the difference of a millimetre can be the difference between life and death. That level of precision demands an extraordinary calm, or what you could also call a cold detachment. But what happens when that same self-possession curdles into something darker? In recent weeks, two surgeons have made headlines for all the wrong reasons. In France, Joël Le Scouarnec was sentenced for abusing hundreds of children – some while they lay anaesthetised in his care. In the UK, plastic surgeon Peter Brooks was convicted of the attempted murder of fellow consultant Graeme Perks, whom he stabbed after breaking into his home in Nottinghamshire. Today, Brooks was sentenced to life imprisonment with a minimum term of 22 years at Loughborough Courthouse. It would, of course, be absurd to taint an entire profession with the acts of two individuals. But it does resurface a long-standing, uncomfortable question: might the very traits that make a surgeon brilliant also mask something far more troubling? 'When people hear the word psychopath, they tend to think of serial killers and rapists,' says Dr Kevin Dutton, a psychologist and the author of The Wisdom of Psychopaths. 'But the truth is that certain psychopathic traits – focus, emotional dispassion, ruthlessness, self-confidence – can predispose you to success, and in an operating theatre, they really come to the fore.' Dutton has spent much of his career trying to prove that 'bad psychopaths' – people who have these characteristics but who can't regulate them – are the ones who commit crimes. A 'good psychopath', by contrast, is someone who can dial those qualities up and down at whim. He recalls one neurosurgeon who was regularly brought to tears by bits of classical music, but who also said, 'Emotion is entropy. I have hunted it to extinction over the years.' Similarly, a cardiothoracic surgeon told him that once a patient was under, he no longer saw them as a person – just a piece of meat. 'Once you care, you are walking an emotional tightrope,' says Dutton, 'but if you see the human body in front of you as a puzzle to solve, then you are more likely to save their life.' 'There's a ruthless part of me' Gabriel Weston, a London-based surgeon and the author of Direct Red: A Surgeon's Story, describes her profession as one that requires you to 'flick off a switch'. Sent to boarding school at a young age (much of British surgery is the product of elite schools), Weston learnt early how to detach emotionally – a skill she found served her well in the theatre. 'If you asked my family, they'd say I'm very emotional in that I cry in films or at art or literature,' she says. 'But there's a ruthless part of me. I use that in surgery – and in other parts of life where emotion just gets in the way.' Over time, Weston learnt to distinguish between two kinds of surgeons: those who switch their feelings back on once they leave the operating room, and those who never do. 'They don't just have psychopathic traits,' she says. 'They live in that space permanently.' They can also come with a reputation for being not just difficult, but dangerous. Harry Thompson*, a British abdominal surgeon, describes a world of towering egos and simmering aggression. 'If you think about it, all surgeons were in the top five of their class,' he says. 'They are all very competitive, and many play sports: they want to prove they are better than everyone. And if you are at the forefront of major surgery, you think you are invincible. It's a boiling-house environment of jealousy, envy and hatred.' He recalls one consultant who stabbed a plain-clothes policeman with a disposable scalpel after being stopped for speeding en route to the theatre. Another smashed a ward office clock when a nurse arrived five minutes late. Physical assaults were, he says, more common than you would think. 'I was in one operation when a student, John, was an hour and a half late, because he overslept. The surgeon thumped the student's head against the theatre wall until he was unconscious, screamed, 'Nobody move!' then started kicking him. No one ever saw John again.' Nor is the patient always spared. 'When I was training, I saw one surgeon thump a patient for removing a drain from his own bottom after an operation because it had become painful,' says Thompson. 'The patient only admitted this (in tears) after the surgeon had made the nurses and junior doctors line up and interrogated each one in turn about who had done it.' Thompson used to work with Simon Bramhall – the liver surgeon who made headlines and was later struck off for branding his initials onto patients' livers using a laser. 'Simon had always been a bit mad,' says Thompson. 'He was fascinated by the programme Randall and Hopkirk (Deceased) and he always wore a white suit [like the character Hopkirk], tie, shoes and socks.' As for tattooing his patients' organs: the initials were discovered by his colleagues only during a second surgery when his once-subtle etching was now grotesquely enlarged by liver damage. While Bramhall's actions sparked public outrage, some in the medical community were nonplussed. Perhaps because this is a far more commonplace occurrence than we realise: an article in Harper's Magazine cited examples of anonymous ophthalmic surgeons who had lasered their initials onto retinas, and orthopaedic surgeons who had etched theirs into bone cement. 'Why would you do that? Ego, of course,' says Dutton, 'and it isn't incidental in surgery. It's selected for. From the moment you start training, you have to fight – quite literally – for your space at the operating table.' 'I find it very freeing not to be pleasant' Dutton researched which of the various disciplines within the profession had the highest rates of psychopathy, and the results are revealing. Number one is neurosurgery (which is bad luck for any fans of Grey's Anatomy), followed by cardiothoracic or heart surgery and then orthopaedic. 'The last one is brutal as you have to smash people's bones,' says Dutton. 'Cardio more than anything is about life and death, but neurosurgery is particularly interesting to me. I think it's because this is the only branch of surgery where, if something goes wrong, you leave the patient permanently crippled or blinded or incapacitated, so only very few people can take such a calculated risk under pressure.' And though these traits are often seen as typically male, women are by no means exempt. Weston says the most difficult surgeon she ever worked under was a woman. 'She was very attractive and well-liked – mostly for being gorgeous and good at her job – but privately she made my life hell. Maybe she didn't like another woman being on the team but she did that horrible thing that women do of presenting this incredibly benign face while being very cruel in private. For months, she blamed me for mistakes that weren't mine, stole credit for my diagnoses, and made me feel like my surgical skills were terrible. She was truly villainous.' And yet, Weston admits, the operating theatre offers her a rare freedom: 'If you are a woman who is quite tough and unsentimental, surgery is a really amazing environment in which you can be yourself. There are many areas of my life – mainly motherhood, but also writing – where there is an expectation that I will be softer than I am. Like Simone de Beauvoir, I find it very freeing not to be pleasant.' Perhaps there is something in all of this (criminal and violent behaviour aside) that we, as patients, secretly find reassuring. We don't want our surgeons to hesitate. We don't want them to be emotional or anxious. We want them to be brilliant: laser-focused, supremely confident, even terrifying if that's what it takes to save us. In life, we dislike arrogance. On the operating table, many of us yearn for it. 'I had one boss,' says Thompson, 'a French surgeon. He used to say: 'There are the porters, the nurses, the managers – and then there are the surgeons. Above them, God. And above God? Me.''

Covid booster warning as Covid NB.1.8.1 cases on the rise
The message comes after health experts also warned of a new COVID-19 variant, with cases of the strain are on the rise around the world. Covid NB.1.8.1 is a variation of the XDV.1.5.1 strain and was first detected back in January 2025. Ifti Khan, superintendent pharmacist at Well Pharmacy, urged those eligible to book as soon as possible and get the booster while it is still available. He said: 'Covid will most likely rise coming into the end of spring and into summer as people mix with friends and family more often. 'We know from previous boosters that they are effective in making sure that patients' symptoms are not as severe as they might have been without so I would urge patients to pop into their local Well Pharmacy store and get their jab. 'Patients have just over two weeks as the spring booster programme ends on June 17 so it would be my hope that those who can get a jab, opt to do so before enjoying socialising during summer.' Mr Khan warned that at this time of year, some people may believe they have hay fever as early symptoms of Covid include a runny or blocked nose or a sore throat. Covid tests can be obtained at any Well Pharmacy. The WHO has placed the Covid NB.1.8.1 "under monitoring" due to the rise in cases worldwide. It is one of six COVID-19 variants currently being monitored. The new 'Strategic and operational plan for coronavirus disease threat management: at a glance' sets out the global framework for supporting Member States in the sustained, integrated, evidence-based management of coronavirus disease threats, including #COVID19, MERS, and… However, the WHO stated that the risk posed by the new variant was "low," and that approved COVID-19 vaccines are expected to be effective against it. The world health experts, in a recent risk evaluation, said: "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 added: "The available evidence on NB.1.8.1 does not suggest additional public health risks relative to the other currently circulating Omicron descendent lineages." COVID NB.1.8.1 has already been detected in 22 countries. These include the likes of Australia, China, Hong Kong, Thailand and the US, according to The Independent. The coming COVID-19 Winter Surge in Australia will show the world where we are actually headed is happening in South-Eats Asia and East Asia are just the 'preludes'...watch how NB.1.8.1 spawns are evolving including PQ.1, PQ.2 and even sub-lineages like PE.1. Cases of the NB.1.8.1 variant have also been confirmed in Northern Ireland, Wales, and "popular British tourist hotspots", the news outlet added.
