New Covid variants NB.1.8.1 and LF.7 detected in India, INSACOG data says: Is there any risk?
While one case of a newly emerging Covid-19 variant NB.1.8.1 has been recorded, four instances of the LF.7 type have also been detected in India.
According to data from the INSACOG, one case of NB.1.8.1 was identified in April in Tamil Nadu, and four cases of LF.7 were detected in Gujarat in May, according to PTI news agency.

As of May 2025, the World Health Organization (WHO) classifies LF.7 and NB.1.8 subvariants as 'Variants Under Monitoring', not as 'Variants of Concern or Variants of Interest'.
'Considering the available evidence, the additional public health risk posed by NB.1.8.1 is evaluated as low at the global level,' the WHO said. 'Currently approved Covid-19 vaccines are expected to remain effective to this variant against symptomatic and severe disease.'

In India, the predominant variant is JN.1, accounting for 53 per cent of tested samples, while BA.2 follows with 26 per cent, and other Omicron sublineages make up 20 per cent.
Doctors have advised people not to panic over the rise of Covid-19 cases linked to the JN.1 variant.
According to them, the strain is not severe and most patients have only reported mild symptoms.

Indian Medical Association Junior Doctors Network (IMA JDN) national spokesperson Dr Dhruv Chauhan said that people need not panic about the JN.1 variant, which is a descendant of the Omicron BA.2.86, according to PTI.
"This is not a lethal variant and it's always better to take precautions like maintaining hand hygiene, wearing masks where necessary such as in hospitals or crowded places and following respiratory hygiene. It is also important to get your symptoms checked by a qualified doctor," said Dr Chauhan.
"The public should remember that panic and chaos can cause more health issues than the disease itself," he added.

James Webb Space Telescope rules out Earth-like atmosphere on rocky planet
The James Webb Space Telescope has found no signs of an Earth-like atmosphere on planet TRAPPIST-1 d, according to a study published Tuesday in The Astrophysical Journal. Using Webb's Near-Infrared Spectrograph (NIRSpec), researchers did not detect common terrestrial gases such as water vapor, methane or carbon dioxide, NASA said. 'At this point we can rule out TRAPPIST-1 d from a list of potential Earth twins or cousins,' lead author Caroline Piaulet-Ghorayeb said. TRAPPIST-1 d is a rocky planet in a seven-world system 40 light-years away. Orbiting a cool red dwarf at just 2 per cent of Earth's distance from the Sun, it sits at the inner edge of the star's temperate, or 'Goldilocks,' zone and completes an orbit every four Earth days, NASA noted. NIRSpec observations showed no spectral fingerprints of key atmospheric molecules. Piaulet-Ghorayeb outlined scenarios that remain possible: an extremely thin atmosphere like Mars; a cloud-shrouded world akin to Venus that hides gases from detection; or a bare, airless rock. 'There are a few potential reasons why we don't detect an atmosphere around TRAPPIST-1 d,' she said. Frequent high-energy flares from the system's red dwarf star can strip atmospheres from close-in planets, making retention particularly difficult. Even so, scientists continue to probe the TRAPPIST-1 worlds because red dwarfs are the most common stars in the Milky Way, NASA said. 'We're really just getting started… and to define the line between planets that can hold onto an atmosphere, and those that cannot,' added co-author Björn Benneke. Webb observations of planets e, f, g and h are underway. Their greater distance from the star could improve the odds of intact atmospheres, though colder conditions make detections tougher, according to NASA. 'All hope is not lost for atmospheres around the TRAPPIST-1 planets,' Piaulet-Ghorayeb said. 'As NASA leads the way in searching for life outside our solar system, one of the most important avenues we can pursue is understanding which planets retain their atmospheres, and why,' said Shawn Domagal-Goldman, acting director of NASA's Astrophysics Division. Results from Webb lay groundwork for future missions like the Habitable Worlds Observatory. (With inputs from NASA's official website)

‘Just soap it': Maneka Gandhi's sister calls rabies 'delicate virus'
An animal activist opposing the Supreme Court's order to relocate Delhi-NCR's stray dogs drew criticism online after describing rabies as a 'mild virus' that dies if the wound is 'washed with soap.' A stray dog sits near a police barricade amid rainfall in Delhi(PTI) The animal activist, Ambika Shukla, was speaking at what appeared to be a demonstration against the August 11 Supreme Court order of relocation of the stray dogs of Delhi-NCR to shelters within eight weeks. "Rabies virus spreads only when the infection reaches the blood through saliva or blood… this is the medium of transmission. But the virus is so delicate that if you wash the wound even with soap, the rabies virus dies," the animal activist said, according to a video shared by X handle 'The Red Mike'. 'That's why, you'll see, in our country where there are billions of people, the number of cases is what? Just 54. So why so few? Because first, rabies is a very rare disease; second, it doesn't spread easily; and honestly, dogs don't bite as much as it's made out to be,' said Ambika Shukla, who is also the sister of BJP MP Maneka Gandhi. Several users, seemingly slamming her for what they suggested was an uninformed statement, urged her to read more about rabies, which is almost always fatal. 'I'm not a doctor, but I can clarify based on medical knowledge. Rabies is not a mild virus; it's a deadly viral disease that affects the nervous system and is nearly 100% fatal once symptoms appear. Washing with soap and water is recommended immediately after a bite from a potentially rabid animal to reduce the risk of infection, as it can help remove the virus from the wound. However, this does not guarantee the virus is completely eliminated, and medical treatment (like post-exposure prophylaxis with vaccines and immunoglobulin) is critical. A doctor should be consulted for confirmation and proper guidance,' one user wrote. 'My humble request to medical fraternity and medical institutions please come forward and tell the masses of this country about fatality of rabies. Let the people must know the cruel face of Rabies,' another user commented. Reports in July cited a nationwide study by the Indian Council of Medical Research–National Institute of Epidemiology (ICMR-NIE), which revealed that India continues to lose over 5,700 lives annually to rabies, despite high levels of awareness and vaccine uptake. While washing wound with soap is essential after a dog bite, rabies is not completely eliminated with it as it only reduces the viral load. Rabies is also not rare, with the World Health Organisation categorising it as a 'serious public health problem in over 150 countries and territories', mainly in Asia and Africa.

Breaking India's Non Communicable Diseases Chain: A Call For Freedom From Chronic Diseases
Noncommunicable diseases silently claim millions of Indian lives each year, but with early action, prevention, and awareness, the country can break this deadly chain. Every Independence Day, we drape ourselves in the tricolour, sing the anthem, and remind each other how hard freedom was won. But for millions of Indians living with chronic illnesses, true freedom remains out of reach. Cardiovascular disease, cancer, chronic respiratory illnesses, and diabetes collectively called noncommunicable diseases (NCDs) now account for 62% of all deaths in Southeast Asia, according to the World Health Organization. Every year, nine million people in the region die from these conditions, many before their 70th birthday. Dr Sabine Kapasi, CEO at Enira Consulting, Founder of ROPAN Healthcare, and UN Advisor shares all you need to know: The threat is not only in the staggering numbers, it lies in the way these diseases silently take root. Poor diets, inactivity, pollution, and genetic predisposition create a slow, invisible chain of damage. By the time symptoms are recognised, it is often too late to reverse them. Yet, most premature NCD deaths are preventable. The COVID-19 surge in May 2021 made this painfully clear. Obesity, diabetes, and other chronic conditions sharply increased the risk of death. Thousands who might have survived the virus did not because their bodies were already weakened by diseases they had been silently managing for years. Globally, NCDs claim 41 million lives annually, including 14 million people aged 30 to 70. Without urgent action, the WHO warns this could rise to 55 million by 2030. For India, the stakes are also economic: reports estimate a loss of $4.58 trillion by 2030 due to NCD-related costs, with heart disease and mental health conditions making up the largest share. But there is hope. India's preventive health ecosystem is growing—startups, government programmes, and grassroots health workers are joining forces. Metabolic trackers, Oura Rings, Tata 1mg dashboards, and workplace health screenings are already spotting risks early. If we sustain this momentum, by 2047 we could win freedom from preventable diseases, redefining independence as the ability to live well. The Government's '75/25" initiative aims to bring care to 75 million people with hypertension and diabetes by December 2025. As of March 2025, treatment had reached 42 million people for hypertension and 25 million for diabetes 89% of the target. This progress is encouraging, but numbers alone cannot dismantle stigma, misinformation, or health neglect. Encouragingly, AIIMS Nagpur and UNICEF Maharashtra are now addressing an often-ignored crisis: NCDs in children. The 2019 Comprehensive National Nutrition Survey revealed alarming trends among children as young as five. Experts warn of a growing risk among children aged 5–9 and adolescents aged 10–19, proof that prevention must begin far earlier than we think. The fight against NCDs is no longer a public health issue alone, it is a national movement. Just as we once came together to win our political freedom, we must now unite to secure the freedom to live long, healthy, and fulfilling lives. view comments First Published: Disclaimer: Comments reflect users' views, not News18's.
