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.

Authorities said the gunman blamed a COVID-19 vaccine for his depression and suicidal thoughts. In an interview following the incident, Kennedy refused to confirm the shooter's motive, stating that political violence was 'wrong.' Neither he nor former President Donald Trump has publicly addressed the motive, even as law enforcement confirmed the CDC was targeted over vaccine health workers urged Kennedy to 'cease and publicly disavow the ongoing dissemination of false and misleading claims about vaccines, infectious disease transmission, and America's public health institutions.'OFFICIALS DEMAND DISAVOWAL OF MISINFORMATION, LINK KENNEDY TO CDC ATTACKThe letter further accused Kennedy of being 'complicit in dismantling America's public health infrastructure and endangering the nation's health by repeatedly spreading inaccurate health information.'Signatories called on the Health and Human Services Department to reaffirm that the CDC's work is 'rooted in scientific, non-partisan evidence focused on improving the health of every American.'

Tailors, weavers, clerks are under construction workers' welfare board, says CAG
Bengaluru: The Comptroller and Auditor General (CAG) Wednesday pulled up Karnataka Building and Other Construction Workers Welfare Board for irregular and unauthorised expenditure of Rs 259 crore during the first wave of Covid-19 in 2020. In a report tabled in the legislature, CAG said the board had initially proposed a preventive health training and check-up programme for five lakh registered construction workers across the state. Its first proposal in July 2020, estimated at Rs 10 crore, was rejected by the finance department, which sought more clarity. A second proposal in Dec 2020 was also blocked after the finance department demanded justification for awarding the project to three agencies directly, without following the tender process, and for seeking 4(g) exemption under the Karnataka Transparency in Public Procurement (KTPP) Act. You Can Also Check: Bengaluru AQI | Weather in Bengaluru | Bank Holidays in Bengaluru | Public Holidays in Bengaluru | Gold Rates Today in Bengaluru | Silver Rates Today in Bengaluru Instead of providing the required justification, the board secretary on April 12, 2021, sent a fresh proposal to the labour department to call for a tender to empanel agencies for a year. He also sought administrative approval to implement the scheme on a pilot basis in Dharwad circle for Rs 9 crore. Soon after, the board decided to split the same work into 30 individual projects, thereby avoiding the need for cabinet approval, and proceeded to call for quotations. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Is it better to shower in the morning or at night? Here's what a microbiologist says CNA Read More Undo The board later approved these projects post-facto in June 2022, citing exemption under Section 4(a) that was originally provided during the first and second waves of Covid-19 for supply of food and ration kits to labourers. The CAG noted, "Thus, the award of contracts from Sept 2021 to May 2022 in contravention to the act/rules resulted in irregular expenditure of Rs 258.8 crore." Responding to the audit, the govt said in Aug 2024 that the work was entrusted directly since a 4(a) exemption was accorded and that there was no contravention of rules. However, CAG rejected this defence, stating the reply was "unacceptable" as it was meant to address the Covid-19 emergency and criticised the labour department for approving work by splitting them into 30 sub-works of Rs 10 crore each despite finance department objections and without cabinet approval. The report also flagged irregularities in the registration of members. Of the board's 42.5 lakh registered workers, CAG found a significant number were not actually construction workers. A random survey of 399 applicants who registered through the Seva Sindhu portal revealed beneficiaries included tailors, clerks, weavers, and others from unrelated professions. The audit recommended that the board devise a mechanism to identify and weed out ineligible beneficiaries. Stay updated with the latest local news from your city on Times of India (TOI).

Want to cut cancer risk by nearly a quarter? Researchers say this diet is the key
Researchers verifying data from the Adventist Health Study-2 found vegetarian and vegan diets may help minimize cancer risks, including less common types. Published in the American Journal of Clinical Nutrition, the study highlights that vegans had the most protective effects, adding to the evidence that plant-based diets support and help to long term health benefits. Tired of too many ads? Remove Ads Tired of too many ads? Remove Ads Results: Who Benefited the Most Vegans with a 24% lower cancer risk compared to nonvegetarians. Lacto-ovo vegetarians (those who consume dairy and eggs) had a 9% lower risk. Pesco-vegetarians (those who include fish and avoid meat) saw an 11% reduction. Younger vegans (under age 65) had a 43% lower risk of prostate cancer, though this advantage was not seen in older vegans. Younger vegans also had a 31% lower risk of breast cancer, with older vegans indicating a similar but less precise trends. For lymphomas, older vegans had a 56% lower risk, while younger vegans did not indicate a major difference. Transitioning to a Plant-Based Lifestyle Protein can be received from beans, lentils, chickpeas, tofu, and whole grains. Iron from plants should be combined with vitamin C-rich foods, like citrus or peppers, to enhance absorption. Vitamin B12, vitamin D, and omega-3s might need supplementation or fortified foods for those avoiding out all animal based products. FAQs: A growing number of researches indicate that consuming more plant-based foods could crucially play a significant role in minimizing cancer risk . A new paper published in the American Journal of Clinical Nutrition supports this evidence, indicating that vegetarians and vegans may have meaningful protection from several cancers, including less common past research has mainly concentrated on common cancers such as breast, colorectal, and prostate cancer, this study focused to go further. To bridge this information gap, researchers examined whether vegetarian diets will offer protection against a variety of cancer types, not just the more common ones but also the rare types. The study experimented whether vegetarian diets, compared to nonvegetarian diets, could have protective benefits for rarer cancers as research team drew findings from the Adventist Health Study-2 (AHS-2) cohort, a large scale project that involves participants across the United States and Canada between 2002 and 2007. The participants were volunteer of the Seventh-day Adventist Church, most of them already follow vegetarian or plant-based consumption. This provided researchers a unique opportunity to analyze dietary patterns in a group.A total of 95,863 people primarily took part, but after excluding those with preexisting cancers, incomplete information, or residency outside covered cancer registries, the final analysis involved 79,468 volunteera. Each volunteer finished a detailed mailed questionnaire, which involved a validated food survey to trace consuming habits from last year. To make sure of accuracy, researchers supplemented this with 24-hour dietary recalls from a subgroup of 1,100 participants and tested dietary the study accounted for many elements that could influence cancer risk such as age, sex, race, and other lifestyle elements enabling them to strengthen the accuracy of the vegetarian diets were associated with lower cancer risk, but the degree of advantage varied depending on the specific diet looking at medium-frequency cancers, vegans once again had the strongest protection, with a 23% reduction in risk, followed by lacto-ovo vegetarians (18%) and pesco-vegetarians (13%).For certain types of cancers, the differences were especially striking:For those interested in adopting a vegetarian or vegan diet , planning is a key professionals highly recommend a gradual transition rather than a switch overnight .
