Covid NB.1.8.1 cases rising: what is known about new variant
Covid NB.1.8.1 is a variation of the XDV.1.5.1 strain and was first detected back in January 2025.
However, reports of the new variant are "growing rapidly", according to the World Health Organisation (WHO), and it is showing some signs of "additional immune evasion" compared to others.
World Health Organisation monitoring COVID NB.1.8.1
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.

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."
Where has Covid NB.1.8.1 been detected?
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.

COVID NB.1.8.1 in the UK
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.
What are the symptoms of COVID-19?
Health organisations are yet to list any symptoms unique to Covid NB.1.8.1.
However, common symptoms of other COVID-19 variants, according to the NHS, include:
High temperature or shivering (chills)
New, continuous cough (this means coughing a lot for more than an hour, or three or more coughing episodes in 24 hours)
Loss or change to your sense of smell or taste
Shortness of breath
Feeling tired or exhausted
Aching body
Headache
Sore throat
Blocked or runny nose
Loss of appetite
Diarrhoea
Feeling sick or being sick
How to tell if you have a cold, the flu or COVID-19
How to protect yourself from COVID-19 variants
COVID-19 vaccines are available in the UK, and are usually offered on the NHS in spring and early winter.
The vaccine is available for those:
Aged 75 or over (including those who will be 75 by 17 June, 2025)
Aged 6 months to 74 years and have a weakened immune system because of a health condition or treatment
Live in a care home for older adults
RECOMMENDED READING:
The NHS said: "The COVID-19 vaccines are offered because viruses change and protection fades over time. It's important to top up your protection if you're eligible."
The vaccine helps:
Reduce your risk of getting severe symptoms
Recover more quickly if you catch COVID-19
Reduce your risk of having to go to hospital or dying from COVID-19
Protect against different types of COVID-19 virus
Eligible people can book in for a vaccination via the NHS website, the NHS App, or by attending a walk-in COVID-19 vaccination site.

Thousands gather for anti-austerity demonstration in London
Thousands of people have gathered to 'send a message' to the Government with a demonstration over spending cuts and welfare reform. Campaign group The People's Assembly said it expected trade unionists, campaigners and activists to attend the event in central London on Saturday. MPs Jeremy Corbyn and Diane Abbott are among those expected to give speeches at a rally in Whitehall. The organisers accused the Government of making spending cuts that target the poorest in society. Representatives from the National Education Union, Revolutionary Communist Party, Green Party and the Rail, Maritime and Transport (RMT) union could all be seen at the march's start point in Portland Place. The large crowd then set off towards Whitehall shortly before 1pm. Many of the protesters were holding placards that read 'Tax the rich, stop the cuts – welfare not warfare'. Other signs being held aloft said 'Nurses not nukes' and 'Cut war, not welfare'. A People's Assembly spokesperson said: 'The adherence to 'fiscal rules' traps us in a public service funding crisis, increasing poverty, worsening mental health and freezing public sector pay. 'Scrapping winter fuel payments, keeping the Tory two-child benefit cap, abandoning Waspi women, cutting £5 billion of welfare by limiting Pip and universal credit eligibility, and slashing UK foreign aid from 0.5% to 0.3% of GDP, while increasing defence spending to 2.5% of GDP, are presented as 'tough choices'. 'Real tough choices would be for a Labour government to tax the rich and their hidden wealth, to fund public services, fair pay, investment in communities and the NHS.' The People's Assembly said it is bringing together trade unionists, health, disability, housing, and welfare campaigners with community organisations under the slogan: No to Austerity2.0. There will be also be speeches from trade union leaders, disability rights activists, anti-poverty campaigners and groups calling for more investment in the NHS and other public services. The spokesperson added: 'We face a growing threat from the far right, fuelled by racism, division and failed politics. We need to see people's lives improve, we need to see the vulnerable cared for and an end to child poverty. 'On June 7, we march for education, for our NHS, for welfare, for refugees, against hate, and for a society in which our children can flourish.'

Warning Wales faces exodus of dentists and patients forced to go private
Warning Wales faces exodus of dentists and patients forced to go private Patients would be seen by any dentist available and check-ups will rise in price and be moved to once every two years if a new NHS dental plan for Wales is approved NHS patients will be seen by any dentist available, rather than their regular practice, and check-ups will be moved to every two years in a planned move the profession warned will cause an "exodus" of staff in Wales. More than six in 10 dentists said they would go fully private rather than take on the Welsh Government's planned shake-up. The changes being proposed are "a leap in the dark that could destroy NHS dentistry in Wales", the British Dental Association (BDA) warned. As a consultation on radical changes to NHS dentistry draws to a close the BDA urged the Welsh Government to heed the warnings of the profession "to avoid a wholesale exodus from the workforce". The Welsh Government has said its proposals will improve patients' access to dental service but the BDA said it would mean more forced to go private. Sign up for our free daily briefing on the biggest issues facing the nation sign up to the Wales Matters newsletter here. Under the shake-up adults would no longer have a regular practice NHS dentist but would be seen by whichever one is available on a first come first served basis. They would stay with that dentist until the course of treatment ends and then be returned the central list. Under-18s would keep the same surgery they are first allocated but dentists warn this could cause problems for families having appointments at multiple surgeries. Prices for NHS check-ups will rise from £20 to £24.75 under the plans. Article continues below "Despite worthy-sounding policy goals – to improve oral health, refocus on prevention, enhance the wellbeing of the workforce, and deliver better value for money – the professional body is warning that the plans as they stand risk achieving the exact opposite results," the BDA said. A survey of dentists across Wales by the BDA found "dentists have been left in an invidious position that risks an exodus from the NHS" with 72% saying they would not be willing to work under the proposed reforms as they stand. More than seven in 10 also said they are likely to reduce their NHS commitment in the event the model is imposed next year and more than six in 10 say they are likely to go fully private. Changes are expected to be fast-tracked for rollout next year. Jeremy Miles, the cabinet secretary for health and social care, has described the package as the "biggest change in nearly 20 years". The BDA said despite "headline focus on prevention" reducing healthier patients to check-up appointments up to 24 months apart could mean diseases, including oral cancers, are not picked up early. Dentists would also be unable to offer timely preventative advice and treatment. There will also be big changes to how NHS dentists are paid with rewards for delivering a 'care package' to patients with ongoing or complex needs. But the proposed level of payment "fails to reflect the true cost of care and risks leaving NHS providers delivering care at a loss", the BDA said. Russell Gidney, chair of the BDA's Welsh General Practice, said: 'On improving access and outcomes and refocusing on prevention the Welsh Government set lofty goals but its reforms risk achieving the exact opposite. 'Now dentists are stuck between the devil and the deep blue sea between a failed status quo and an unpopular untested alternative. "Ministers must be willing to listen, pilot plans, and avoid a leap in the dark that could destroy this service.' In a statement to the Senedd on March 18 Mr Miles said the new general dental services contract will be implemented from April 2026. He said the reforms would be the biggest in nearly 20 years and the central aim will be to make it easier to access NHS dentistry. He said instead of recalling everyone every six months for a routine check-up the new contract will be based on prevention and needs-based provision of treatment. The online BDA survey answered by 176 dentists across Wales also shows only: 2% of dentists responding feel that changes would support the long-term sustainability of NHS dentistry in Wales; 2% agree that reforms would improve population health with only 5% saying that they would enhance prevention; 2% feel reforms would support continuity of care with the same proportion believing it would enhance early detection of oral health conditions; 8% say that reforms would actually improve access to NHS care, and; 6% think the proposed system would provide good value for money for the taxpayer. Responding to the BDA's comments and findings a Welsh Government spokesman said: 'Under the new contract most people would continue their relationship with their practice and continuity would be strengthened for people with poor oral health. 'We are committed to providing better access to NHS dentistry for those most in need and at risk and to making NHS dentistry more attractive to dentists and their teams. The consultation on the proposed new contract is now live for the public and professional alike to have a say in shaping these once-in-a-generation reforms.'
