Younger population seeing high rates of infection amid Covid surge: Experts
As India confronts a fresh surge in Covid-19 cases, doctors suggest that the virus is disproportionately affecting younger age groups, with the 18-45 age bracket bearing the brunt of the infection.
According to data available on the Union health ministry's Covid dashboard, India has 5,976 active cases from 29 states and Union Territories (UTs) as of June 19. Of these, Kerala has the highest caseload at 1,309, followed by Gujarat and Delhi at 1,046 and 632 cases, respectively.
While the government does not give an age- or gender-wise breakup of cases, doctors are seeing a noticeable increase in Covid-19 cases among young adults, specifically those aged between 18 and 45.
Tushar Tayal, consultant-internal medicine at CK Birla Hospital, Gurugram, said that on average, 10-12 patients per day were coming to him with flu-like symptoms and a small but steady percentage of them were testing positive for Covid-19.
'This may be indicative of a silent surge that is frequently overlooked because other viral infections overlap and (there's) an overall reduction in the rate of testing,' he added.
Aakashneel Bhattacharya, consultant-infectious diseases at Paras Heath in Gurugram said that 80-85 per cent of Covid patients coming to him fell into the same 18-45 age bracket.
Young adults previously considered to be at relatively low risk of severe illness are now showing heightened susceptibility, particularly those with a poor follow-up history of vaccination or waning immunity.
Divya K S, an infectious disease specialist at Apollo Hospitals in Sheshadripuram, Bengaluru, said that waning immunity over the years, in addition to the emergence of immune-evading strains, made the younger population more vulnerable.
Tayal said that in the 18-25 age group, most came with high-grade fever, throat pain, tiredness, body pain, and sometimes gastrointestinal symptoms of nausea or diarrhoea. Some also complained of a dry cough lasting for days and mild difficulty in breathing.
In individuals over 30, symptoms persisted longer, and there were more instances of prolonged fatigue or post-viral cough, he added.
Commenting on the reasons, Bhattacharya said younger people were at high risk of contracting the infection as they were the ones who mostly went out and mixed up with other people in the community.
'Till now, we are not seeing patients developing serious pneumonia or having low oxygen saturation. While a few patients may have had minor pneumonia, they are not requiring oxygen,' he added.
Tayal, however, said that although most cases of Covid in younger patients were not serious, there should be caution against complacency. 'Reinfections are being observed even in persons who have been vaccinated or infected before, pointing to changing viral strains,' he added.
Another reason was that many younger patients were delaying getting tested, assuming the infection to be a seasonal flu or viral fever, he further said.
Nidhin Mohan, consultant-internal medicine, Narayana Health City, Bengaluru, said that there was a spike among individuals who had recently travelled, especially for work or weddings, without taking adequate precautions.
'Infectious strains that spread faster within a group that is in close contact with each other can result in more case numbers among younger populations, who tend to be at the centre of workplace and social interactions,' said Deepesh G Aggarwal, consultant physician and head of department for critical care medicine at Saifee Hospital, Mumbai.

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.

1,720 set to receive free disability aids in B'pur
Bhagalpur: To promote mobility and independence among the differently-abled and elderly citizens, the ministry of social justice and empowerment will distribute free assistive devices under its ADIP and Rashtriya Vayoshri Yojana (RVY) schemes in Bhagalpur. A total of 1,720 registered beneficiaries from the district – 636 under ADIP and 1,084 under RVY – will receive the aids during a three-day distribution camp starting on June 24 at Sandy's Compound. Union minister of state B L Verma and Bhagalpur MP Ajay Kumar Mandal will distribute wheelchairs, tricycles, hearing aids, walking frames, crutches and other prosthetic devices at the event. MP Ajay Kumar Mandal, who played a key role in facilitating the camp, said, "This is a major initiative by the Centre. It will greatly assist the 1,720 registered beneficiaries in Bhagalpur district." He added that most beneficiaries are from Jagdishpur, Sabour, Nathnagar, Sultanganj, Sahkund, Pirpainty and Goradih blocks. The scheme targets physically challenged persons and senior citizens from below poverty line (BPL) families. "The goal is to provide scientific and modern devices to support their rehabilitation and improve their independence. This includes physical aids and assisted-living devices for the elderly suffering from age-related disabilities," the MP said. The initiative is part of the Centre's broader effort to empower marginalised sections through direct support and inclusion.

Disability-related questions in Census must be framed differently, say rights groups
Past population counts, including the last Census in 2011, have historically undercounted people with disabilities, according to rights activists and experts who have written to the Office of the Registrar General of India, seeking a 'shift in approach' to framing disability-related questions in the upcoming Census exercise. In the past, 'simplistic' questions with negative connotations, posed by enumerators with minimal training, wthout considering accessibility concerns, have all contributed to low disclosure, they said, claiming that the 2011 Census had counted 'only 2.21%' of the country's disabled population per some estimates. They sought time to make suggestions for better methodologies for the upcoming Census. After delaying the 2021 Census, the Union government on June 16 notified dates for the next Census, to be completed by March 2027. 'Most undercounted' The 2011 Census recorded about 2.68 crore people with disabilities (PwD) across the country. In their letter to the ORGI and the Secretaries of the Home and Statistics Ministries, disability rights organisation Nipman Foundation and policy think tank The Quantum Hub noted that extrapolations from the World Health Organisation's global estimates suggested that India had at least 200 million, or 20 crore, people with disabilities – almost ten times what was counted in the Census in 2011. In the letter, Nipman Foundation founder Nipun Malhotra said that PwDs are amongst the 'most undercounted' populations in the country. He argued that the 2011 Census had under-reported the number of PwDs in the country because of several factors, including 'simplistic' questions being framed with 'negative connotations' given the existing social stigma. Mr. Malhotra said that questions that asked whether one was mentally or physically disabled, only providing space for a 'yes/no' answer, resulted in low disclosure. 'Moreover, enumerators also received minimal training in disability awareness, contributing further to under-reporting,' he said in the letter. 'Improve accessibility, question formats' He added that the Census process must also be made accessible through the use of Indian Sign Language, Braille, and screen-reader friendly documents, further urging authorities to employ interpreters to ensure meaningful participation of disabled people. The rights group argued that the Washington Group on Disability Statistics, under the UN Statistical Commission, 'offers a more functional approach'. This involves a six-question set, which Mr. Malhotra said was 'most suitable' for national Censuses. For instance, one questions is, 'Do you have difficulty seeing, even if wearing glasses?', and provides a graded response scale, from 'No difficulty at all' to 'Cannot do it at all'. The Nipman Foundation further posited that this was 'much-improved methodology compared to the present approach'. 'These changes are critical to ensuring more accurate and inclusive data collection,' it said in the letter.
