Low-dose CT chest scans could help detect pneumonia in at-risk patients while exposing them to only small amounts of radiation, a new study has found. The research, published in Radiology: Cardiothoracic Imaging, shows that ultra-low-dose scans can effectively detect pneumonia in patients with compromised immune systems, enabling doctors to treat the infection before it becomes life-threatening. According to the researchers, these scans expose patients to just 2% of the radiation dose used in a standard CT scan.

"This study paves the way for safer, AI-driven imaging that reduces radiation exposure while preserving diagnostic accuracy,” lead researcher Dr Maximiliano Klug, a radiologist with the Sheba Medical Center in Ramat Gan, Israel, said in a news release. He added that CT scans are the gold standard for detecting pneumonia but there are concerns regarding the risk posed by repeated exposure to radiation. There is a solution- ultra-low-dose CT scan. However, the problem is that these scans can be grainy and hard to read, researchers said.

Study Gives Solution To This

To overcome that, Klug's team developed an AI program that could help "de-noise" low-dose scans, making them sharper and easier to read. Between September 2020 and December 2022, 54 patients with compromised immune systems who had fevers underwent a pair of chest CT scans -- a normal dose scan and an ultra-low-dose scan. The AI program cleaned up the low-dose scan, and then both sets of images were given to a pair of radiologists for assessment. Radiologists had 100% accuracy in detecting pneumonia and other lung problems with the AI-cleaned low-dose scans, but 91% to 98% accuracy in examining the scans that hadn’t been improved through AI, results show.

"This pilot study identified infection with a fraction of the radiation dose," Klug said. "This approach could drive larger studies and ultimately reshape clinical guidelines, making denoised ultra-low dose CT the new standard for young immunocompromised patients.

How Can You Detect Pneumonia?

Pneumonia is a lung infection that causes the air sacs in the lungs to fill with fluid or pus and can be caused by bacteria, viruses, or fungi. The symptoms can range from milk to severe, which includes:

Coughing with or without cough

Fever

Chills

Trouble breathing

Chest pain, especially when breathing deeply or coughing

Sweating or chills

Rapid heart rate

Loss of appetite

Bluish skin, lips, and nails

Confusion.

How to detect Pneumonia in coughing newborns and toddlers?

Pneumonia can severely affect newborns and young children as their lungs are comparatively more sensitive. As per Dr Goyal, young children can cough for various reasons including seasonal infections and tonsillitis, which is very common in this age group. But if they look visibly irritable and have poor sleep patterns, then parents must reach out to an expert. "I am not saying that parents must visit a hospital but any local paediatrician would be able to detect pneumonia in your kid.

UK Faces Shortage Of This Common Pain Medicine Till June

Updated Feb 18, 2026 | 09:26 AM IST

SummaryPrescription-strength co-codamol will remain in short supply until June due to delays importing key ingredients from India. Patients are being told to taper doses while authorities coordinate alternatives, though health boards warn substitutes cannot meet demand fully.

A shortage of prescription-strength co-codamol is set to continue until at least June, leaving thousands of chronic pain patients across the UK uncertain about how they will manage daily symptoms. The Scottish government has confirmed limited availability of the strongest 30/500mg tablets, while health boards warn alternative medicines may not fully cover demand.

The shortage is linked to delays in authorization by the Indian government for exporting key codeine-based ingredients needed to manufacture the drug.

Patients Told To Taper Use

Many patients say they first learned of the disruption through calls from local health services. Some have already been advised to slowly reduce their dose to avoid withdrawal symptoms.

Jocelin Harrison, who has relied on the medication for more than three decades after five spinal surgeries, said she was contacted by NHS Lanarkshire and instructed to cut down gradually.

“The only advice I’ve been given so far was to reduce the tablets and try to manage my withdrawal symptoms,” she said, as reported by the BBC.

“I was not offered any other advice or possible replacement pain killers and it’s a great worry for me and other chronic pain sufferers throughout Scotland and the UK.”

Doctors warn that abruptly stopping co-codamol can trigger headaches, nausea, sweating and a sudden increase in pain, particularly for long-term users.

Why Does This Drug Matter So Much?

Co-codamol combines paracetamol with the opioid codeine and is commonly prescribed after surgery or for persistent musculoskeletal conditions. It comes in three strengths: 8mg, 15mg and 30mg of codeine with 500mg paracetamol.

The lowest strength is available over the counter, but the stronger forms require a prescription and are widely used by patients with chronic pain. Because codeine can cause dependence, tapering rather than stopping suddenly is considered essential.

Health boards say supplies of alternative strengths are also limited, making it difficult to simply switch everyone onto another version.

Guidance issued locally states patients, except those undergoing cancer treatment, should gradually reduce usage until stopping completely. No new patients will be started on the medication until supplies stabilize.

What Are The Alternatives?

NHS Grampian has urged pharmacists to prioritize existing stock carefully. However, it stopped short of telling patients to immediately begin cutting back, highlighting variation in local guidance.

Officials acknowledge substitutes exist, but warn they cannot meet the expected rise in demand from patients switching medicines.

Authorities Now Work On Solution

Scotland’s chief pharmaceutical officer Alison Strath said the issue ultimately sits with UK-wide medicine supply systems but confirmed discussions are ongoing.

“Supply issues are expected until June 2026 and we are in regular contact with the UK government to seek assurances they are doing all they can to resolve this,” she said, adding that affected patients will be contacted directly about alternative treatment options.

The UK Department of Health and Social Care said most medicines remain readily available and manufacturers are working to restore production.

The shortage highlights the global nature of generic drug manufacturing. Medicines such as co-codamol 30/500mg are typically produced using ingredients sourced from India and China, meaning regulatory or production delays overseas can quickly affect patients at home.

For now, patients are being urged not to contact GP practices unless advised and to wait for further instructions from their health providers.

Measles Outbreak In UK: A measles outbreak has been confirmed in London's north east area, noted the BMJ. As per the medical journal, the outbreak is among the unvaccinated children. The medical journal also noted that there have been 96 laboratory confirmed cases of measles in England between January 1 to February 9, 2026 and more than a third, which is 34 cases are from Enfield. BMJ also noted that Enfield is also the area with lowest vaccination rates.

As per the data by the UK Health Security Agency or the UKHSA, only 64.3% of 5 year-olds Enfield received both doses of the measles, mumps, and rubella or the MMR vaccine in 2024 and 2025. The majority (74 of 96, 77%) of measles cases confirmed in the UK so far this year were in children aged 10 and under. Some 64% of cases have been in London, 26% in the West Midlands, and 4% in the East Midlands.

Measles Outbreak In UK: Previous Cases And How It Made A Comeback

Last month, the World Health Organization revoked the United Kingdom’s measles elimination status after the virus was found to be circulating continuously for over a year.

In 2025, a child in Liverpool died after contracting measles, prompting renewed pressure on the NHS and government to address its return. England recorded 959 laboratory-confirmed cases that year. Although lower than the 2,911 cases in 2024, it still marked the highest annual total since 2012.

Vaccine uptake has steadily declined over the past 12 years. Only 84.4% of children in the UK receive both doses of the MMR vaccine by age five, far below the 95% coverage needed for herd immunity.

Why Has Measles Return To The UK?

In late 2023, measles outbreaks were reported in the UK, which led to a surge in cases in 2024. Vaccination uptake at the end of 2024 was 92% for the first dose, however, for the second dose, it was below 82%.

Dr Vanessa Saliba, consultant epidemiologist at UKHSA said, "Infections can return quickly when childhood vaccine uptake falls - measles elimination is only possible if all eligible children receive two MMRV doses before school. The NHS is making vaccination easier, including offering the second MMRV dose earlier at a new 18-month appointment to boost uptake and support elimination goals."

She also noted that children and adults must get vaccinated as NHS also offers catch-up jabs.

Dr Baharat Pankhania, from the University of Exeter, as reported by the BBC said, "Measles is an infection that can be prevented by vaccine - and it's extremely concerning that in the UK we now have pockets of low or no vaccine uptake. We urgently need to remedy this situation." Pankhania also noted that there is a need to make the access to GPs easier, and for an effort that could immunize babies in their homes and counter wrong information around vaccine safety.

Updated Feb 17, 2026 | 07:36 PM IST

SummaryHealth Minister JP Nadda launches SAHI and BODH initiatives at the India AI Summit to develop an inclusive and globally competitive health AI ecosystem, which will also help address equitable healthcare across the country.
India AI Summit: Union Health Minister Nadda Launches SAHI And BODH Initiatives To Boost AI In Healthcare

The Union Minister of Health and Family Welfare, JP Nadda, today launched two key national initiatives -- the Strategy for Artificial Intelligence in Healthcare for India (SAHI) and the Benchmarking Open Data Platform for Health AI (BODH) to boost the role of AI in the country's healthcare ecosystem.

The initiatives, launched at the India AI Summit at Bharat Mandapam, in the national capital, are aimed at promoting safe, transparent, and accountable AI in healthcare. It will also help strengthen the digital health ecosystem for equitable healthcare access.

What is SAHI and BODH?

SAHI is a national guidance framework to enable the safe, ethical, evidence-based, and inclusive adoption of AI across India’s healthcare system.

It aims to provide strategic direction on governance, data stewardship, validation, deployment, and monitoring of AI solutions, while supporting States and institutions in responsible adoption aligned with public health priorities.

"SAHI is not merely a technology strategy but a governance framework, policy compass, and national roadmap for the responsible use of AI in healthcare,” said Nadda.

He stated that SAHI will guide India in leveraging AI in a manner that is ethical, transparent, accountable, and people-centric. Nadda also emphasized that SAHI provides a structured framework for collaboration, ensuring that innovation flourishes while public interest remains paramount.

The second initiative, BODH, was developed by the Indian Institute of Technology Kanpur in collaboration with the National Health Authority. It is a privacy-preserving benchmarking platform that enables rigorous evaluation of AI models using diverse, real-world health data without sharing underlying datasets.

As a digital public good under the Ayushman Bharat Digital Mission, it is designed to strengthen trust, transparency, and quality assurance in Health AI deployment.

"The collaboration between Government and academia has led to the development of BODH -- the Benchmarking Open Data Platform for Health AI -- which provides a structured mechanism for testing and validating AI solutions before deployment at scale,” said Nadda.

Nadda reiterated that AI solutions must be rigorously evaluated for performance, reliability, and real-world readiness. Together, SAHI and BODH represent India’s commitment to building a trustworthy, inclusive, and globally competitive health AI ecosystem grounded in innovation, responsibility, and public trust.

AI An Indispensable Enabler to Viksit Bharat

Earlier, delivering the keynote address at a session themed “Innovation to Impact: AI as a Public Health Game-Changer”, at the Summit, Anupriya Patel, Union Minister of State for Health and Family Welfare, highlighted AI as an "All-Inclusive Intelligence".

She also emphasized AI's potential in addressing "health inequities across the country".

Patel called technology -- particularly AI "an indispensable enabler" in India's race towards the vision of a Viksit Bharat by 2047.

She highlighted the potential role of AI on India’s vast and diverse population, the rural–urban divide, and the dual burden of communicable and non-communicable diseases, which present unique challenges.

She also noted that AI has been integrated across the entire continuum of healthcare -- from disease surveillance and prevention to diagnosis and treatment.
