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.

India has successfully linked the health records of more than 100 crore people with Ayushman Bharat Health Accounts (ABHA) under the Ayushman Bharat Digital Mission (ABDM), the Ministry of Health and Family Welfare said today.
Implemented by the National Health Authority, the milestone marks a major step towards building an integrated, citizen-centric, and interoperable digital healthcare ecosystem in the country.
“The linking of over 100 crore health records with ABHA is an important milestone in the journey of Ayushman Bharat Digital Mission. ABHA-linked health records empower citizens with secure and consent-based access to their health information and support continuity of care across the healthcare ecosystem,” said Dr. Sunil Kumar Barnwal, CEO, NHA.
According to the Ministry, more than 450 public and private health technology solutions have integrated with the ABDM ecosystem, enabling digitisation and seamless exchange of health records across healthcare facilities.
The ministry said ABDM doubled the number of linked health records from 50 crore in February 2025 to over 100 crore in just 15 months.
Nearly 10 crore health records are now being linked every two to three months. From fewer than 1,000 linked records during its initial phase to over 100 crore today, ABDM has evolved into one of the world’s largest digital health ecosystems.
Uttar Pradesh emerged as the leading contributor with over 15.03 crore ABHA-linked health records, followed by Andhra Pradesh with over 11.95 crore linked records.
Bihar, Rajasthan, and Gujarat also recorded major progress by linking over 7.37 crore, 6.32 crore, and 4.77 crore health records, respectively.
Among the major government programs and digital platforms contributing to the milestone are:
Private health technology partners and ABDM-enabled digital solutions have also contributed significantly towards the creation and linkage of ABHA-linked health records.
ABHA is a unique digital health identity that allows citizens to securely link and access their health records across hospitals, clinics, laboratories, and healthcare providers.
Through ABDM’s consent-based health information exchange mechanism, citizens can digitally share their medical records with registered healthcare providers while maintaining the privacy and security of personal health information.
“ABDM is designed to place citizens at the center of the digital health ecosystem. With consent-based sharing of health records, individuals can access their medical information whenever required and share relevant records with healthcare providers digitally. This will help make healthcare delivery more accessible, efficient, and patient-centric,” Barnwal said.
The Ayushman Bharat Digital Mission is creating the digital public infrastructure required for an interoperable healthcare ecosystem through key digital building blocks such as:
With over 100 crore health records now linked with ABHA, ABDM has marked another milestone towards creating longitudinal digital health records for citizens and enabling a more connected, paperless, efficient, and patient-centric healthcare ecosystem in the country.

Amid the rising cases of Ebola virus infection in nations like the Democratic Republic of the Congo, Uganda, and South Sudan, the whole world has gone to an alert mode. The state government of Kerala has declared that it will keep the visitors from the countries flagged by the World Health Organization (WHO) under mandatory health surveillance for up to 21 days after arrival.
The government of India has already issued an advisory on this important issue. In accordance with the direction, the state government of Kerala has also taken some strict steps to protect the general public from this infectious virus. On Thursday, at the meeting of the State Rapid Response Team, Health Minister K. Muraleedharan said the measure was being adopted as an additional precaution.
The Union Health Ministry has also propagated a stricter stance on preventing the virus outbreak in the country. The ministry emphasizes its stance by issuing orders to strictly follow the special health guidelines.
As per the new norms, the travelers from Ebola-affected nations are asked to report to the health authorities at the airport if they feel symptoms commonly associated with Ebola, like fever, headache, fatigue, vomiting, diarrhoea, muscle pain, sore throat, or bleeding. Those who had any contact with confirmed or suspected Ebola patients have also been informed by the health authorities.
The state government has made screening of passengers stricter in the international airports and seaports.
In addition to that, the authorities have also searched isolation wards and intensive care facilities throughout the state to find those who require treatment or observation.
The health minister of the state ordered ample training of healthcare personnel in infection prevention and control. There is also emphasis on the use of PPE kits, proper treatment protocols, and critical care management.
What is Ebola?
Ebola is a severe and, in most cases, deadly disease caused by viruses predominantly found in Africa. The spread of the disease happens through contact with infected body fluids.
Some symptoms can indicate a possible infection. This includes fever, weakness, headache, muscle pain, vomiting, diarrhea, sore throat, and unexplained bleeding. This eventually leads to severe complications like bleeding, organ failure, and death. The hosts of the virus are animals like bats, primates, and antelopes.
Meanwhile, Tedros Adhanom Ghebreyesus, WHO Chief said he was “deeply concerned about the scale and speed of the epidemic”. He noted that the numbers are expected to rise given the time taken to detect the virus.
The WHO says it could take up to nine months before a vaccine against this particular species of Ebola is ready.
Two possible "candidate vaccines" against the Bundibugyo species are being developed, but neither has gone through clinical trials yet, WHO advisor Dr. Vasee Moorthy said, according to the BBC.
Speaking to journalists in Geneva, Tedros said 51 cases have been confirmed in the Democratic Republic of Congo — where the first case was reported — and two in neighboring Uganda.

Mental disorders are on the rise worldwide, and nearly 1.2 billion lives are now affected by them. A recent study published in The Lancet has revealed this very crucial trend. The study was conducted by researchers at the Institute for Health Metrics and Evaluation (IHME) in collaboration with the University of Queensland.
This study shows that the number of people affected by the mental disorder has almost doubled since 1990. It also emphasizes the role of mental disorder in the case of disability, as the research suggests that it has crossed cardiovascular disease, cancer, and musculoskeletal conditions, leading to disability. Notably, the study has revealed that mental disorders affect people of different sexes and ages disproportionately.
The research was done on a massive scale from 1990 to 2023. The researchers studied the impact of mental disorder on both sexes, in 25 age groups, 21 regions, and 204 countries and territories.
Over the years, mental disorders have caused more and more mayhem in people's lives. Disability adjusted life years (DALYs) show the very impact of mental disorders on life. DALYs measure the health loss. It calculates the years lived with disability and years of life lost due to premature death.
According to this very measuring system, we can see that the mental disorder and its impact on overall life reached another zenith in 2023. That year, mental disorders alone caused 171 million disability adjusted life years (DALYs). This made mental disorder the fifth biggest contributor to total disease burden. Notably, in 2023, mental disorders had a 17 percent share of total life lost due to disability throughout the world.
The mental disorder affects people of both sexes at all stages of life, but the impact can differ massively with age.
