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.

Excessive screen time use is harming sleep, mental health, learning, and development of children, according to a new advisory by the US surgeon general’s office, which urged parents to limit children’s screen time.

Even as President Donald Trump's nominee for surgeon general awaits confirmation, the "Harms of Screen Use" bulletin warns that children and teens are spending more time on their digital devices than on sleep or school, the USA Today reported.

It noted that excessive screen use is linked to heavy or compulsive screen use

  • anxiety,
  • depression,
  • poor academic performance,
  • behavioral problems
  • developmental delays.

Health and Human Services Secretary Robert F. Kennedy Jr. said evidence of risks to children’s physical and mental health is “mounting,” even though screens can also provide some benefits.

The advisory promotes the slogan “Live real life,” encouraging children and families to replace excessive screen use with in-person activities and healthier routines.

Alongside the report, the officials also released a toolkit recommending steps for parents, schools, healthcare providers, and policymakers to help reduce screen dependence and encourage safer technology habits among young people.

The advisory also links excessive and "compulsive" screen use to

  • poor sleep and school performance,
  • mental health issues like anxiety and depression,
  • behavioral and social issues, substance abuse, and developmental disruptions.

The report aligns with recent studies, which show how too much screen time affects developing minds.

Recent findings from the All India Institute of Medical Sciences, Delhi, suggest that early digital exposure to children before the age of one increases the baby's risk of autism.

The findings led by the Department of Pediatric Neurology showed that infants exposed to high levels of digital media at around one year of age are significantly more likely to display autistic signs by the time they reach age three.

India has also issued pediatric and education guidelines advising parents to limit screen exposure for young children, though there is no nationwide ban. States like Karnataka and Andhra Pradesh have also taken up action against social media use and screen time.

Countries banning screen time

While countries are not fully “banning” screen time, several of them have introduced restrictions, guidelines, or proposed laws aimed at reducing children’s screen time, especially around smartphones and social media in schools.

  • France banned smartphones in primary and middle schools in 2018 and has tested stricter “digital pause” policies for students under 15.
  • China has some of the world’s toughest rules, including limits on video game play for minors, restrictions on nighttime gaming, and proposed limits on smartphone use for children.
  • South Korea introduced laws targeting gaming addiction among minors, including past shutdown rules that blocked late-night gaming for children.
  • Netherlands and Finland have encouraged schools to restrict phones in classrooms to improve concentration and learning.
  • Australia has debated stronger social media age restrictions, and several states have tightened school phone bans.
  • United Kingdom schools widely enforce smartphone bans, while lawmakers continue discussing stricter online safety rules for children.
  • Sweden has pushed for reduced screen exposure in early childhood education, emphasizing printed books and traditional learning methods.

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.

The Growing Adoption Of ABDM

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.

What Is ABHA?

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.

Key Digital Building Blocks Of ABDM

The Ayushman Bharat Digital Mission is creating the digital public infrastructure required for an interoperable healthcare ecosystem through key digital building blocks such as:

  • Ayushman Bharat Health Account (ABHA)
  • Healthcare Professionals Registry (HPR)
  • Health Facility Registry (HFR)
  • Health Information Exchange and Consent Manager (HIE-CM)
  • Unified Health Interface (UHI)
  • National Health Claims Exchange (NHCX)

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.

WHO Says Vaccine Could Take Months

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.
