AIIMS-led study finds infections contracted in hospital due to catheter use prevalent across India
Bloodstream infections
Antibiotic resistance -- in which antibiotic drugs are rendered ineffective because disease-causing microbes have become immune to them -- can extend one's hospital stay and treatment costs, adding stress to a public healthcare system.
Estimates published in The Lancet Global Health journal show that on average, around nine bloodstream infection events occur every 1,000 days that a central line -- a catheter inserted in a patient's large vein instead of an intravenous line -- was in place in the intensive care units (ICUs) of Indian hospitals.
'Central line-associated bloodstream infections', or CLABSI, are preventable infections -- often acquired from a hospital environment -- and significantly contribute to illness and death in low- and middle-income countries, including India.
The researchers said that tracking rates of bloodstream infections in ICUs can help countries develop preventive measures suited to a healthcare system. However, setting up a surveillance that systematically tracks infections due to catheter use or other hospital-acquired infections calls for a significant amount of resources and is a challenge in low- and middle-income countries, including India, they said.
Study highlights
The team analysed data from 200 intensive care units received by the Indian Healthcare-Associated Infections (HAI) surveillance network from 54 hospitals across the country over a period of seven years.
"During the surveillance period from May 1, 2017, to April 30, 2024, 8,629 laboratory-confirmed CLABSI events, 3,054,124 patient-days and 977,052 central line-days were recorded. The overall pooled CLABSI rate was 8.83 per 1,000 central line-days," the authors wrote.
Highest rates of bloodstream infections linked to central line catheter use were seen to occur during 2020-21, coinciding with the COVID-19 pandemic, which the researchers said may be due to overwhelmed ICUs, staff shortage and compromised infection prevention measures.
The study -- first large-scale observational one, providing a standardised surveillance report of CLABSI in India -- provides a valuable opportunity for a quality improvement-based approach for the reduction of CLABSI, the authors said.

From Army to Navy to Air Force: Surgeon Vice Admiral Arti Sarin, DG AFMS reveals what she learnt from each service
Surgeon Vice Admiral Arti Sarin, Director General of the Armed Forces Medical Services (DG AFMS) has the rare distinction of serving in all three branches of the Indian armed forces. At She Shakti 2025, the spotlight is on women who are leading from the frontlines. In an inspiring segment, Firstpost's Managing Editor Palki Sharma, spoke to Surgeon Vice Admiral Arti Sarin, Director General of the Armed Forces Medical Services (DG AFMS), about her path to a historic leadership position. Surgeon VAdm Sarin has a rare distinction to her name: she has served in all three branches of the Indian armed forces. She served as a lieutenant to captain in the Indian Army, from surgeon lieutenant to surgeon vice admiral in the Indian Navy, and was an air marshal in the Indian Air Force as well. STORY CONTINUES BELOW THIS AD The flag officer, who also has the distinction of being the first woman to be appointed as DG AFMS, spoke about the lessons in leadership from her time in each service. 'I started in the Army very young. But I think the Armed Forces confer leadership on their officers very early. Of course you have a small medical inspection room that you take care of. That starts your path to looking after a place both administratively and also looking after patients. So, I learnt a little bit of that kind of leadership there, and then I moved on,' she said. Surgeon VAdm Sarin, who spent 36 years in the Navy as part of the AFMS, spoke about how postings in remote locations taught her how to survive with less resources and how to communicate, among other things. She went on to say, 'I moved into the Command Hospital in Pune. The good thing about AFMS is that since it is a tri-services organisation, we move smoothly between Army, Navy, and Air Force. I've served in Army hospitals in naval uniform for 12 years.'

Although the flag officer served only a short time in the Indian Air Force, she learnt key lessons there. 'I learnt a lot from the aviators[…]Learnt to be very precise, very quick, very professional,' she said.

Indian astronauts only ones trained in both US and Russia: Shubhanshu Shukla
New Delhi: Indian astronauts will have an edge in their preparation for the country's human spaceflight programme, as they have trained in both Russian and American technologies, said Shubhanshu Shukla, group captain of the Indian Air Force and the first Indian to set foot on the International Space Station (ISS). Speaking at a press conference in New Delhi on Thursday, Shukla said that the prolonged training phase has seen Shukla and his three compatriots—Prasanth Balakrishnan Nair, Ajit Krishnan and Angad Pratap—travel across, Moscow, Bengaluru and Florida to get access to training experiences for spaceflight in American firm SpaceX's Crew Dragon, as well as Russian space agency Roscosmos' Soyuz human-qualified space vehicles. 'This gives us in India a distinct technical advantage in terms of being prepared for a wide variety of circumstances, engineering and technologies, once we take off for space in the designated timeline of stepping on the moon by 2040,' Shukla said. The press conference, also addressed by Jitendra Singh, Union minister for space, and V. Narayanan, chairman of the Indian Space Research Organisation (Isro), came days before India geared up to celebrate its second national space day, commemorating two years of Isro's lunar mission, Chandrayaan-3, landing on the moon. Shukla said that the mission also prepared him for both scientific experiences and the physical rigour that is inevitable with space travel. 'When I first interacted with my countrymen from the ISS, many of you would have seen that I looked visibly different at that point. The first three days in space can be uncomfortable, but then your body adjusts—and the same holds true for when you land back and face the impact of gravity. These are aspects that you can't experience during training on the ground,' he added. Adding to Shukla's statement, Singh said that India's space associations with other nations is a sign of 'increasing confidence that the world has on India's innovation.' 'For the first time in history, India's space technologies are now meeting global scientific benchmarks. This gives India unprecedented global influence, and shows evidence that more and more countries are now trusting India to collaborate upon space technologies. India's biggest strength has been the ability of conducting major scientific projects with frugality, and all things taken together, we now stand at a juncture from where India's private space economy can grow 5 times in less than a decade,' the minister said. Giving an example of this, Narayanan said that Isro played a crucial role in detecting a leak in Crew Dragon, the launch vehicle used by Shukla's Axiom-4 space mission, which took off after several delays on 25 June and returned safely to earth on 15 July. The Isro chief also added that nearly 80% of all technical tests for India to prepare for its Gaganyaan series of manned space missions have been completed. By the end of the current fiscal year, Isro aims to complete the remaining tests as well. The first unmanned trial of Gaganyaan, which would fly to space with a humanoid robot laden with sensors onboard, is expected to happen before the end of this calendar year. However, amid talks of preparation for India's own manned space mission, Shukla refused to reveal a 'surprise' that he left aboard the ISS for Rakesh Sharma, the first Indian in space. 'It will be revealed in due time, in the presence of Wing Commander Sharma,' Shukla said.

Dengue Spike In Mumbai, Kolkata, Other Cities: What's Driving It & How To Stay Safe
With the monsoon in full swing, multiple Indian cities are seeing renewed dengue activity, alongside stepped-up municipal action. In Mumbai, civic monsoon reports indicate higher overall vector-borne disease activity in 2025, with dengue infections rising versus last year through July; clinicians have flagged an OPD surge as humidity and waterlogging increase. Kolkata has recorded recent deaths and a cluster of fresh cases that have prompted the Kolkata Municipal Corporation (KMC) to intensify anti-dengue operations across several neighbourhoods. Lucknow has reported a steady climb in cases through mid-August as residents point to patchy fogging and waterlogging concerns. Nagpur has detected mosquito larvae in thousands of homes during door-to-door surveillance, triggering a citywide blitz on breeding sites. This pattern is familiar: intermittent rains create small collections of clean water in and around homes, which are the perfect nursery for Aedes aegypti and Aedes albopictus, the day-biting mosquitoes that spread dengue. The good news: dengue is largely preventable with simple, consistent household measures. Here's what's been reported in these cities, unpack why cases typically rise now, and share evidence-based steps from Indian and global public-health authorities that you can implement today. What Indian Cities Are Reporting Mumbai Brihanmumbai Municipal Corporation (BMC) data and hospital observations show rising vector-borne disease activity this monsoon, with dengue infections higher than 2024 through July and clinicians warning of increased OPD load as humidity and waterlogging persist. The BMC has issued advisories on stagnant water removal, nets/repellents, and fever vigilance. Kolkata Following two dengue deaths in mid-August, KMC has intensified vector-control drives in hotspots such as Ballygunge and Behala, and urged Puja committees to prevent water stagnation at pandals. Hospitals report a weekly uptick, with some patients showing gastro-intestinal symptoms alongside classic fever and body ache. Lucknow As of mid-August, Lucknow has seen a notable increase in dengue cases in the past 45 days, with residents citing waterlogging and clogged drains in several localities; the municipal corporation has initiated citywide cleanliness and insecticide-spray drives to curb breeding. Nagpur An intensive door-to-door survey in early August found mosquito larvae in nearly 8,000 of 1.46 lakh homes checked, prompting an NMC "dengue blitz" with fogging, larviciding and awareness campaigns. Reported case numbers since July remain in single digits but the larval index signals substantial transmission risk without sustained action. Why Dengue Cases Rise Now: The Science And The Season Dengue risk typically increases during/after monsoon due to intermittent rainfall, humidity and waterlogging, which create numerous micro-containers (coolers, buckets, plant trays, tarpaulins, construction sites) for Aedes mosquitoes to lay eggs. These mosquitoes bite during the day and prefer clean, stagnant water-even tiny amounts are enough. Public-health guidance emphasises weekly elimination of standing water and screening of homes. Clinically, dengue illness lasts 2-7 days of fever; warning signs (severe abdominal pain, persistent vomiting, mucosal bleed, lethargy, restlessness) often appear as the fever begins to subside, which is why medical advice discourages self-medication with NSAIDs and urges prompt evaluation for warning signs and adequate fluid management. How To Stay Safe: Practical Steps For Families Here are some science-backed methods of preventing dengue and keeping your family safe: Eliminate mosquito breeding Indian NCVBDC and WHO guidelines prioritise source reduction as the most effective first line of defence. Empty, scrub, dry: buckets, trays under flowerpots, AC drip pans, pet bowls, coolers, fridge trays, discarded tyres. Cover overhead tanks and drums; repair leaking taps. Check construction sites and terraces for pooled rainwater; escalate to RWAs if needed. Personal protection, especially for day bites CDC's dengue pocket guide and WHO recommendations endorse these measures for households. Use repellents on exposed skin (per label instructions); reapply as directed. Wear full-sleeved, light-coloured clothing; use window/door screens. Sleep under mosquito nets (helpful for sick family members to prevent household spread). Photo Credit: Pexels Community measures that work NCVBDC's programme guidance stresses integrated vector management with community participation. Support fogging/larviciding drives but remember they are supplementary; they don't replace weekly source reduction at home. Report stagnant water and blocked drains to local civic bodies; many corporations run monsoon hotlines during this season. When to seek care, and what to avoid Clinical red flags or symptoms of dengue should not be taken lighty, so here's what you should note: Seek medical attention for high fever with headache, retro-orbital pain, myalgia/arthralgia, rash, or any warning signs (bleeding gums, black stools, persistent vomiting, severe abdominal pain, extreme weakness). Avoid ibuprofen or other NSAIDs until dengue is ruled out; use paracetamol for fever as advised by a clinician. Maintain oral fluids (ORS, coconut water, soups) unless restricted by your doctor. Special precautions for vulnerable groups Pregnant women, young children, older adults, and those with comorbidities should seek early assessment if febrile during dengue season. Households with a confirmed dengue patient should adopt strict mosquito-avoidance to prevent further transmission at home. This monsoon's dengue picture is evolving city by city: Mumbai hospitals and BMC reports indicate higher activity; Kolkata has intensified civic action after recent deaths; Lucknow has reported a recent uptick amid sanitation concerns; and Nagpur's larval surveys show significant household breeding. Household vigilance is the most reliable defence. Note: City counts and civic responses are dynamic during monsoon; readers should also follow their local municipal advisories for the latest locality-specific updates.
