Seven symptoms you need to look out for as doctors issue Covid warning
A new variant now spreading across Europe and multiple other continents could leave people with a host of unpleasant symptoms - that don't feel like classic Covid
Health officials have warned that people could experience a host of nasty and unusual symptoms if they contract the latest Coronavirus strain.
The new variant, named NB.1.8.1, was designated a "SARS-CoV-2 variant under monitoring (VUM)" on May 23, one of six emerging variants currently under WHO monitoring. As of this month, it has crossed multiple continents, with cases flagged in the UK and Ireland in Europe, and further afield in the US and Australia. People have been urged to stay at home for days on end if they find they have symptoms of the new Covid variant, which are a far cry from the classic flu-like signs of their predecessors.
While early signs of Covid once included symptoms like a severe cough, sore throat and high fever, NB.1.8.1 is felt most acutely in the gastrointestinal tract.
Symptoms of the variant include:
Nausea
Vomiting
Diarrhoea
Heartburn
Bloating
Constipation
Abdominal pain
Dr Lara Herrero, associate professor and virology research leader at Griffith University in Australia, explained in an article posted on The Conversation that the variant appears to be spreading faster than its predecessors. Of those, Dr Herrero said, it is most similar to subvariants of the Omicron lineage.
She said: 'The evidence so far suggests NB.1.8.1 may spread more easily and may partially sidestep immunity from prior infections or vaccination.
'Reports suggest symptoms of NB.1.8.1 should align closely with other Omicron subvariants." The WHO has said the same, stating in its report that the variant has obtained a series of mutations that allow it both to spread easier and potentially evade antibody protections afforded to people by previous infections.
The organisation explained: "Spike mutations at position 445 have been shown to enhance binding affinity to hACE2, which could increase the variant's transmissibility."
It adds: "Mutations at position 435 shown to reduce the neutralisation potency of class 1 andclass 1/4 antibodies, and mutations at position 478 shown to enhance the evasion of Class 1/2 antibodies." People who exhibit any symptoms have been told to stay indoors by the UK Health Security Agency (UKHSA) which advises people to "avoid contact with vulnerable people and stay at home if possible" for 48 hours.

Americans urged to stay vigilant for new unusual Covid symptom caused by dangerous Chinese strain
Americans are being urged to look out for a distinct symptom caused by a new Covid variant spreading in the US. Multiple sources say that patients infected with the strain — dubbed NB.1.8.1 — are suffering from a painful sore throat that feels like a 'razor blade' or shattered glass. Dr Zhong Nanshan, a leading epidemiologist in China, told the country's state media that 'razor blade throat' was now more commonly being reported by patients. And many Chinese citizens are also posting online saying they have been afflicted by the symptom after catching Covid, warning it is painful and leaves them feeling 'completely drained'. Doctors in the West are now raising awareness about the symptom that is being linked to the variant. The NB.1.8.1 strain has sent cases surging in China, with the proportion of ER patients testing positive for the virus jumping over one month from 7.5 to 16.2 percent from March to May this year. It is also taking hold in other neighboring countries including India and Thailand, and in California, where the proportion of cases caused by the variant has risen from two percent to 19 percent since April. More than a dozen cases have also been reported in Washington state, alongside infections in Ohio, Rhode Island and Hawaii. International travelers infected with the variant were reported arriving in Virginia and New York City. The World Health Organization says that early analysis suggests the variant is more infectious, and may now make up half of all cases globally. But they say there is no evidence that the strain is more likely to cause severe illness or death. Patients infected with the variant are said to also be reporting other symptoms of a Covid infection similar to previous waves, including a cough, fever, muscle aches and congestion. Dr Nanshan told a state broadcaster: 'This round of Covid is not much different from the previous ones. 'The early symptoms were similar, including fever, headache, general fatigue, and sore throat. 'But this time, clinical reports showed that the symptoms of razor blade throat were more obvious, and there were more coughs.' And posts on the social media platform Weibo by Chinese citizens also reveal individuals are suffering from the symptom. One wrote: 'During lunchtime a few days ago, a colleague was coughing so wildly I thought she choked on food. 'She said it was a lingering effect from this Covid wave. When I asked about her main symptom, she said "razor blade throat".' A second said: 'I've been hit with razor blade throat, and feel completely drained.' And a third added: 'Post-Covid razor blade throat is brutal - swollen, painful, and I can barely speak. Any quick remedies?' The comments are being picked up by doctors in the UK, where the variant has also been detected, and also by the international organization World Health Network. The Switzerland-based group, which tracks Covid symptoms and variants, said in an alert: 'Commonly reported symptoms include a severe sore throat described as 'razor-blade throat fatigue, mild cough, fever, muscle aches, and congestion.' A spokesperson for the organization added to 'These consistent reports of unusually intense throat pain—distinct from earlier variants—are part of what led us to flag this symptom in our notice. 'We continue to monitor both media coverage and direct input from WHN-affiliated clinicians and communities globally.' It comes after some physicians in Ohio called for the return of mask mandates to emulate areas like Hong Kong. Dr Amy Edwards, a pediatrician at Case Western Reserve University in Cleveland, told CBS News last week that anyone who feels 'a little under the weather' should consider masking up. Another expert calling for masks is Dr Melanie Matheu, an immunologist from California who previously studied at the University of California, San Francisco. The US test positivity rate — proportion of swabs detecting the virus — rose slightly to 2.8 percent in the week to May 31, the latest available, compared to the previous seven-day spell where it was 2.7 percent. The proportion of ER patients infected with Covid remained at the same level of 0.3 percent of all those admitted over the same period. While Covid deaths still appear to be dropping. The latest figure, for the week to May 10, shows 250 deaths were recorded over that seven-day spell compared to 277 in the previous seven-day period. These levels are far below those in previous Covid periods, including the start of the 2021 wave where the US peaked at reporting 3,700 Covid deaths per day. The test positivity rate reached a high of 13.8 percent in early 2022 amid the start of the Omicron wave of infections. And are below those reported at the same time last year, when the test positivity rate was 3.5 percent and there were about 344 Covid deaths reported every week. About 0.4 percent of ER visits were also been linked to the virus.

Mpox is still a health emergency, WHO says
June 9 (Reuters) - The mpox outbreak is still a public health emergency, the World Health Organization said on Monday, with the health body's director-general issuing a revised set of temporary recommendations. The WHO first declared the emergency in August last year, when an outbreak of a new form of mpox spread from the badly-hit Democratic Republic of Congo to neighbouring countries. A public health emergency of international concern is WHO's highest form of alert.

GP issues warning over new Covid symptom amid fears Nimbus variant will sweep the UK this summer
Doctors are urging anyone with a 'razor blade' throat that they could have a new and highly contagious Covid variant. Dubbed 'Nimbus', the strain is descended from the super virulent Omicron, with 13 cases having already been found in the UK, following a surge in cases in China, Singapore and Hong Kong. Whilst experts say Nimbus symptoms are broadly similar to earlier versions of the virus a 'razor blade sore throat' could be a key sign of the new variant. According to Dr Naveed Asif, a GP at The London General Practice, this distinctive symptom is characterised by a sharp, stabbing pain when swallowing, often at the back of the throat. Other symptoms linked to the strain include redness in the back of the mouth and swollen neck glands as well established common Covid symptoms like fever, muscle aches and congestion. 'However, symptoms can vary widely so vigilance is key', Dr Asif told Manchester Evening News. According to the NHS, Covid symptoms include a high temperature, a new continuous cough, a loss or change to sense of smell or taste, shortness of breath and feeling sick. Whilst only 13 British cases of Nimbus have been identified so, these figures likely underestimate how far the variant has spread. This is because the number of Covid tests carried out has massively decreased since the height of pandemic and lockdown. Data from the UK Health Security Agency (UKHSA) shows the number of people testing positive for Covid has hit record levels this year and is already 97 per cent higher than numbers recorded in March. Experts have also warned that the new strain could lead to a surge in Covid cases over the summer and have urged the vulnerable to get vaccinated. Even those who were previously vaccinated or infected could be at risk of the catching the virus as previously built-up immunity fades over time. Professor Lawrence Young, a virologist at Warwick University, put the potential surge in cases down to warmer weather and busier social lives. 'We are very likely to see a spike of infections over the next couple of months, possibly by later this month or in July. But it's difficult to predict the level of this infection wave,' he told The i Paper. 'Population immunity, either from vaccination or previous infection, is waning and, unlike other respiratory viruses such as flu, the Covid virus continues to spread in hot and humid weather,' he said. Lab studies suggest Nimbus can infect human cells more efficiently than previous strains, making it more likely to infect people. However, there is currently no evidence Nimbus is more likely to cause severe illness or death in those it infects compared to previous variants. But infection with the virus can still be deadly for more vulnerable groups. Covid was a factor in the deaths of just over 300 people in England in May, according to the latest official figures. Experts have also said that current Covid vaccines, which have been reformulated to combat Omicron descendants, are expected to remain effective against Nimbus. According to the World Health Organisation, Nimbus, scientifically known as NB.1.8.1, now accounts for 10.7 per cent of Covid infections worldwide, compared to just 2.5 per cent a month prior. Dr Gayatri Amirthalingam, UKHSA's deputy director, said the organisation was keeping a close eye on Nimbus. 'UKHSA is monitoring all available data relating to SARS-CoV-2 variants in the UK and abroad, and we continue to publish our findings in our regular Flu and Covid-19 surveillance reports,' she said. 'NB.1.8.1 has been detected in small numbers in the UK to date, but international data suggests that it is growing as a proportion of all Covid-19 cases.' Currently adults over the age of 75, care home residents, and those aged six months and over who have weakened immune systems are all eligible for a free Covid vaccine across the UK. This includes organ, bone marrow or stem cell transplant patients, people living with HIV, cancer patients undergoing chemotherapy or radiotherapy and those with genetic disorders affecting the immune system. UKHSA data suggests people who had a Covid jab as part of last spring's booster campaign were 45 per cent less likely to need hospital care for the virus in the weeks that followed compared to the unvaccinated. The agency has urged all people eligible for a vaccine to get jabbed to protect themselves from both NB.1.8.1 and Covid in general.
