Covid cases no cause for alarm, but stay vigilant, says ICMR DG
Is there a surge in Covid-19 cases?
There is a slight increase. Until March, there were almost zero cases of Sars-Cov-2, all the respiratory illness cases were either influenza A or B or RSV (Respiratory Syncytial Virus), and one or two cases of the human metapneumovirus. Since the end of April, we are seeing more cases of Sars-Cov-2. The virus is here, it's circulating.
Where were the samples taken from?
ICMR runs in 73 labs in medical colleges across the country. Samples are taken from both severe and non-severe patients of SARI (Severe Acute Respiratory Infection) and ILI (Influenza-like Illnesses). We test for all the six-seven common viruses in every patient; so, it is not that we have suddenly started testing for Covid.
How serious does the situation seem?
There is no need to be alarmed... Only isolated mild cases have been reported so far. But should we be complacent? The answer is no. Should we be vigilant? The answer is yes.
Are the current variants more virulent?
At this moment, there is no evidence that any one of the circulating variants causes more severe disease than the previous variants. There is an evolution of variants across the world… it is a sub-variant of omicron that we have seen — the BA.2.86 that has a sub-variant called JN.1.
What are the variants in circulation?
There is JN.1, LF.7, XFG and NB.1.8.1. However, all these have evolved from the Omicron variant BA.2.86 (also known as pirola) either in pure or recombinant form. None of them, however, have been shown to be more severe than what we already know about Covid-19.
Do we have enough vaccines to deal with the current variants?
We do not make vaccine for every variant… We do have the ability to make a vaccine against a variant but we don't need to make a vaccine. The need of the vaccine is to prevent severe disease and death; we have never given vaccines to prevent mild Covid cases. If severe cases and death are not happening in large numbers, then we don't need to give vaccine. We are seeing about 1,000 cases currently, if this number increases then we will consider what is the best vaccine to give.

Mohali: Homi Bhabha hospital begins DNA testing for advanced cancer diagnosis
The Homi Bhabha Cancer Hospital and Research Centre (HBCHRC) in New Chandigarh has started in-house DNA and RNA-based Next Generation Sequencing (NGS), marking a major upgrade in cancer diagnostic services in the region. Hospital director Dr Ashish Gulia said that only a few hospitals in this region currently offer such testing. (HT file) The department of oncopathology at the hospital will now use NGS technology to analyse genetic mutations in cancer patients, enabling doctors to personalise treatment based on individual tumour profiles. The facility is available for both solid tumours and blood cancers. Officials said that until now, samples for this test had to be sent to laboratories in Mumbai. The new facility will reduce diagnostic time significantly and allow quicker initiation of targeted treatments. 'NGS is a molecular diagnostic method that allows detailed analysis of DNA and RNA to identify genetic drivers of cancer. It also helps detect hereditary cancer syndromes and monitor disease progression,' they added. Hospital director Dr Ashish Gulia said that only a few hospitals in this region currently offer such testing. He explained that cancer treatment has evolved from broad chemotherapy protocols to targeted therapies that depend on genetic profiling. Dr Sankalp Sancheti, head of the oncopathology department, noted the test's complexity and emphasised that the development of the facility was a team effort.

Nine BBMP staffers to be probed over Covid bills
BENGALURU: A Departmental Enquiry (DE) has been ordered against nine BBMP officials in connection with the alleged irregularities in the release of payments related to Covid-19. Following the recommendation from the Justice Michael D Cunha Committee, which was constituted to probe the alleged irregularities in the procurement of Covid-19, notice was issued to 28 officers of the corporation, including engineers, doctors and the officers of the accounts department, seeking an explanation about the purchase of medicines and medical supplies during that period. 19 officers were given a clean chit. The health department, however, ordered an investigation into the remaining officers. 'These are officials in the BBMP health department who failed to give clarity over expenses and bills, and hence the matter was escalated to the BBMP Administration Department. If these officials fail to clarify the doubts, action will be initiated,' said Sirajuddin Madani, Chief Health Officer. Notices have been issued to 15 private companies that supplied materials during the Covid period. The committee has suggested the recovery of Rs 13 crore given to 15 private companies as 'extra'. BBMP Officers and Employees Association president Amruth Raj said it's time the black sheep are shunted out. 'Those involved in dereliction of duty should be suspended and jailed,' he said.

Can drones deliver blood in emergency? India test gives hope, flags hurdles
In a race against time, drones beat the ambulance.A drone successfully transported blood bags from GIMS Hospital in Greater Noida to Lady Hardinge Medical College in the heart of Delhi's Connaught Place. Though the experiment was carried out in 2023, the ICMR team of scientists — who monitored the drone as it covered the 35 km distance in just 15 minutes, an hour faster than a traditional ambulance — published a detailed report only ICMR study published in June, titled 'Adopting Drone Technology for Blood Delivery: A Feasibility Study to Evaluate Its Efficiency and Sustainability', stated that drones are a promising alternative for transporting life-saving blood and its components. The study concluded that drones can safely and efficiently serve as first-response vehicles in medical emergencies. This study comes months after drones slashed eye tissue delivery time by nearly 70%. A drone flew 38 km from Sonipat to Jhajjar in just 40 minutes. A road journey takes over two Delhi, drones have even taken to fighting mosquito-borne the ICMR scientists cautioned that more scientific evidence was needed to assess the challenges, and an assessment of the quality of the blood transported using a there are challenges, some natural, others that need to be ironed out, such as regulatory hurdles, weather conditions, battery life, maintenance, safety concerns, costs, and better integration with existing healthcare Indian Healthcare Future-ready With 'i-Drone'.Trial run of blood bag delivery by drone successfully flight carried 10 units of whole blood samples from Govt Institute of Medical Sciences & Lady Hardinge Medical College, for the first time in India. Dr Mansukh Mandaviya (@mansukhmandviya) May 10, 2023WHY USE OF DRONES TO TRANSPORT BLOOD IS COMPLEXDrones are revolutionising healthcare by providing cost-effective, fast delivery of medical supplies to remote and underserved areas. In India, the Ministry of Health and Family Welfare aims to make healthcare "future-ready through the i-Drone initiative".But transporting blood via drone is more challenging than transporting organs because blood requires strict temperature control and careful handling to maintain its quality and safety, whereas organs have different preservation needs and are triggered by occasional to the ICMR study, the drone trial for blood transportation was largely successful. It demonstrated that blood and its components can be safely transported by following established guidelines. In October 2021, under the i-DRONE initiative, ICMR successfully conducted India's first drone-based delivery of vaccines and medical supplies in the Northeast. (Image: Ministry of Science and Technology) WHAT DOES ICMR'S STUDY ON DRONE BLOOD DELIVERY SAY?In the study, four types of blood components (like whole blood, packed red blood cells, fresh frozen plasma, or platelets) were safely transported using drones with special temperature-controlled boxes. The drone delivery was much faster than using a van. The drone delivery took just 15 minutes, while a van took over an hour for the same special drone that can take-off and land like a helicopter and fly up to 40 km was used to carry 4 to 6 blood bags along with cool gel packs, weighing about 4 kg, and all flights followed India's drone safety was no damage (called hemolysis) to the blood during transport. The temperature stayed within safe limits during and after the flight. While some small changes were seen in certain blood components, these changes happened with both drone and van transport, and overall, the quality of the blood remained safe, the ICMR study said."Hence, the drone is a potential alternative to explore in tropical countries as a first response vehicle in emergencies," it said."But more scientific evidence is required about the practicality, operational challenges and impact on the quality of blood after transportation via drone," the study noted further. Rwanda was the first to launch a medical drone framework in 2016 with Zipline. The UK, after NHS-backed trials, has a national plan for BVLOS medical deliveries by 2026. (AFP Image for representation) advertisementCHALLENGES OF USING DRONES FOR BLOOD DELIVERY?The ICMR confirmed that blood and its components can be safely transported via drones if strict guidelines are followed. It recommended maintaining blood component-specific temperatures to prevent hemolysis or bacterial contamination, using specialised cooling systems and real-time monitoring to ensure blood study advised rigorous validation of drone vibrations to avoid damaging red blood cells, plasma, or platelets, and emphasised that pre-flight checks are vital. Compliance with aviation regulations and coordination with air traffic control were also said to be critical for safe beyond visual line of sight operations, particularly in rural areas.A pan-India robust regulatory framework is also diverse topography of high mountains and humid plains may affect drone current high costs of drone technology, urban congestion and limited rural blood bank infrastructure hinder scalability, flagged a 2025 study in the Journal of Transport and Public said, drones won't replace ambulances anytime soon, but they may outrun them when it counts most. In crunch situations like foggy mountains, traffic jams, drones delivering blood to the needful will make all the difference. But, challenges may clip the wings of medical drone delivery in India. What the study shows is that drones aren't just tools of surveillance or strike or wedding photography. They're now allies in saving lives. To make that promise fly, the gamechanger must get a real chance.- Ends advertisement
