Nimbus (NB.1.8.1) Covid Variant: Razor Blade Sore Throat And Other Symptoms To Watch Out For
A new Covid variant, 'Nimbus,' scientifically known as NB.1.8.1, has been causing a noticeable surge in cases across Asia, the UK, and the US. This Omicrom sub-variant is gaining attention due to its distinctive and extremely painful sore throat symptoms. The severity of the throat pain has been described as "razor blade throat" by patients. According to data from the Centers for Disease Control and Prevention (CDC), Nimbus accounted for approximately 37% of US cases within two weeks as of June 7.
Nimbus cases around the world
According to health officials, Nimbus has contributed to nearly a third of new cases. As per the Global Initiative on Sharing All Influenza Data (GISAID), the NB.1.8.1 variant has been detected in at least 13 US states, including California, New York, New Jersey, and Illinois.
This variant has also been reported in the UK. The UK Health Security Agency (UKHSA) reported a 10% jump in hospitalisation with 947 patients admitted in the week ending May 31.
CDC has also confirmed that NB.1.8.1 has triggered a sharp rise in hospitalisations across China.
A notable rise in infections has also been reported in many parts of Asia including Singapore, Thailand, and India.
Razor blade and other symptoms of Nimbus or NB.1.8.1
Other than severe throat pain, infected individuals experience Omicron-like symptoms including congestion, fatigue, mild cough, fever, loss of taste and smell, runny nose, loss of appetite and muscle aches. Less common symptoms include diarrhea and nausea.
The new variant does not have any unique characteristics. Symptoms are generally mild to moderate. However, elderly and immune-compromised people remain at higher risk for severe disease.
NB.1.8.1 is currently being monitored by the World Health Organization (WHO) and was first detected in China earlier this year. NB.1.8.1 is a descendant of the Omicron family. According to experts, the NB.1.8.1 sub-variant does not cause serious illness. However, it appears to be highly transmissible.
Covid cases in India
India's active Covid-19 caseload stands at 5,976, according to Health Ministry data. A total of 507 people recovered from Covid-19 in the past 24 hours. India is witnessing a rise in Covid-19 cases over the past few weeks due to emerging Omicron sub-variants particularly, LF.7, XFG, JN.1, and the newly identified NB.1.8.1.

What we know about Covid variant ‘Nimbus' known for ‘razor blade throat' amid surge in cases
A new Covid variant is on the rise. According to reports, the most recent variant of the coronavirus has been identified as the "Nimbus" variant, known for causing a 'razor blade throat'. The new variant 'Nimbus', officially known as the NB.1.8.1, as per an Associated Press report, has been detected in several US states such as Washington, New York, California and Virginia. Furthermore, the variant has also been detected in Australia and the UK. As per the World Health Organisation, Nimbus is a subvariant of the Omicron variant of SARS-CoV-2, which causes Covid-19. Under the WHO list of Covid variants to watch for, Nimbus has been classified as a 'variant under monitoring'. 'The WHO assesses the additional risk to the global public as currently low, and existing Covid-19 vaccines are considered effective in preventing severe disease,' Dr Naveed Asif, a general practitioner at The London General Practice, told The Independent. Also Read: India's active Covid cases near 6,500; 'newly emerging XFG variant' found, says INSACOG | What is it? As per the data from the Centres for Disease Control and Prevention (CDC), the new Omicron variant is currently responsible for one-third of coronavirus cases in the United States (37 per cent). Furthermore, according to the Global Initiative on Sharing All Influenza Data, the new variant has been detected in at least 13 US states. The variant was also detected in the UK. As per the UK Health Security Agency (UKHSA, Britain saw a 10 percent jump in hospitalisation with around 947 patients admitted in the week ending May 31. of this, at least 13 cases have been attributed to Nimbus. The Nimbus variant also carries symptoms similar to the Omicron variant, such as congestion, fatigue, mild cough, fever, loss of taste and smell, runny nose, loss of appetite and muscle aches. However, the variant has garnered global attention due to an unusually painful symptom called "razor blade throat." As the phrase says, patients have likened this symptom to having a razor blade stuck down your throat. Despite this symptom, WHO has stated that the Nimbus variant does not appear to cause more severe illness than previous strains and is still at the low risk category.

India flags concerns on ILO's biological hazard pact for informal sector
India has cautioned the International Labour Organisation (ILO) that the 'universal' coverage envisaged under the recently adopted convention on protecting workers from the devastating impact of uncontrolled biological hazards in the workplace may be challenging—particularly for the informal sector and micro, small and medium enterprises (MSMEs). India also expressed concern about the applicability of the convention beyond the workplace setting. "We understand the importance of labour safety, but it is also important to ensure that the definitions of the proposed instrument are not so broad that they apply beyond the workplace setting. The [Convention's] universal coverage approach may be challenging, particularly for informal sectors and MSMEs," said Labour Minister Mansukh Mandaviya in his address at the International Labour Conference (ILC). Virat Jaiswal, general secretary of the National Front of Indian Trade Unions (NFITU), said the government is concerned that the definitions used in the instrument are too broad, potentially resulting in its application outside the workplace and leading to over-regulation. Last week, during the annual ILC in Geneva, the United Nations body adopted the Biological Hazards in the Working Environment Convention—the first-ever international instrument specifically addressing biological hazards in the workplace at a global level. The convention aims to safeguard workers who may come into contact with microbes, DNA material, bodily fluids, parasites, toxins, allergens and other biological agents during the course of their work. It applies to all workers in all branches of economic activity but requires countries to take specific measures in high-risk sectors and occupations. B Surendran, organising secretary of the Bhartiya Mazdoor Sangh (BMS), said the need for such a convention was reinforced by the COVID-19 pandemic, which killed millions globally, disrupted economies and crippled health systems. 'A lot of people contracted COVID-19 at the workplace. Hence, the convention sets out mechanisms and frameworks to deal with such eventualities. It has always been important to address biological hazards in workplaces, but now it's becoming even more critical,' he added. The ILO's 187 member states—equally represented by governments, employers and trade unions in the ILC—are now required to ratify the convention.

ICMR sets up high performing computing facility to boost genomic surveillance and pandemic preparedness
Working to address limitations faced during the COVID-19 pandemic due to conventional computing infrastructure, the Indian Council of Medical Research (ICMR) has now introduced its first high-performance computing facility at its National Institute of Virology (NIV) facility in Pune. The acquisition of the state-of-the-art computing cluster, named NAKSHATRA, comes soon after India reported a surge in COVID-19 cases, though the number of active cases have dipped marginally over the last two days. ICMR-NIV Pune director Naveen Kumar noted that several new pathogens and COVID variants are being reported. 'It's essential that we upgrade to stay ahead in enhancing public health research capacity,' he said. Genomic research upgrade Attributing the emergence of novel pathogens to increased globalisation, global warming, and deforestation, Dr. Kumar said that his centre has been doing extensive sequence analysis using multiple strains, which used to take weeks. 'Now with the upgrade we can do the same work in 24 to 48 hours. It has increased the capability of our country for genomic surveillance, which will help us in pandemic preparedness,' he said. The NAKSHATRA facility enables enhanced storage and optimises the pipeline for genomic research, which ensures better viral genomic surveillance capacity and national preparedness for any future pandemic. The facility supports faster analysis of complex genomic data, allowing scientists to detect new disease threats sooner, respond to outbreaks more efficiently, and accelerate AI-driven vaccine and drug development. Central data repository Developed under the Pradhan Mantri Ayushman Bharat Health Infrastructure Mission (PMABHIM), the facility forms the cornerstone of a new project, called the High Performance Computing Next Generation Sequencing Hub. The Pune facility will initially serve five ICMR institutes across the country, acting as a central repository for sequencing data. Sarah Cherian, group leader of the Bioinformatics and Data Management Group and principal investigator of the project, provided a comprehensive overview of the cluster's capabilities and its role in genomic research. She said that the computing cluster is tailored to support complex bioinformatics workflows, including next-generation sequencing, transcriptomics, phylogenetics, metagenomics, and structural bioinformatics. Genomic monitoring impact Already, NIV Pune has played a key role in the management of the COVID-19 pandemic. Previously significant genetic alterations in the virus had triggered the second and third wave and ongoing genomic monitoring and analysis helped in early detection of variants of interest and concern. 'This in turn had helped in paving the way for implementing the booster dose of vaccination for COVID,' the institute noted.
