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.

Thailand has become the seventh country in the WHO South-East Asia Region to achieve rubella elimination, the World Health Organization (WHO) said.
It joins Bhutan, DPR Korea, Maldives, Nepal, Sri Lanka and Timor-Leste.
“The World Health Organization announced that Thailand has been verified for eliminating rubella as a public health problem, marking a major milestone in the country’s efforts to protect children, women and families from vaccine-preventable diseases,” WHO said.
Thailand launched its Expanded Programme on Immunization in 1977 and introduced a rubella-containing vaccine for girls aged six in 1986. The programme expanded to all one-year-old children in 1993.
Since then, Thailand has strengthened routine immunisation, outbreak response and surveillance, with a focus on underserved and mobile populations.
The programme focused on reaching underserved and mobile populations, rapidly investigating suspected measles and rubella cases through fever-and-rash surveillance, and maintaining laboratory-supported surveillance to detect and respond to virus transmission.
The South-East Asia Regional Verification Commission (SEA-RVC) reviewed Thailand’s surveillance, immunisation, outbreak response and programme data in June 2026, followed by a verification visit in July.
The Commission recommended Thailand for rubella elimination verification. Elimination means no endemic transmission for at least 12 months, supported by a high-performing surveillance system.
The WHO verification also confirmed that Thailand has systems in place to sustain this achievement.
“This verification is a proud moment for Thailand and a tribute to decades of commitment by our health workers, volunteers, partners and communities. By eliminating rubella, Thailand has protected newborns from preventable lifelong disabilities and reaffirmed its commitment to equitable health services for every child and family. We will sustain this gain and intensify efforts towards measles elimination,” said H.E. Mr Pattana Promphat, Minister of Public Health, Thailand.
Rubella, also known as German measles, is a contagious viral infection spread through droplets from coughs and sneezes. Symptoms are usually mild and may include fever, rash and swollen lymph nodes.
However, infection during pregnancy can cause miscarriage, stillbirth or congenital rubella syndrome (CRS), which can lead to lifelong birth defects. The risk is greatest when infection occurs early in pregnancy, particularly during the first trimester.
“Rubella is a terrible disease. It looks like measles, but in pregnant moms it causes spontaneous abortion and stillbirth. Babies born with congenital rubella syndrome have profound disabilities. Rubella elimination everywhere is a huge public health win,” said Dr Angela.
CRS can cause lifelong hearing and vision impairment, heart defects and developmental delays.
Before widespread vaccination, rubella was a leading cause of preventable congenital disabilities worldwide, according to WHO.
Rubella can be prevented with safe, effective and affordable vaccines.
WHO estimates that rubella causes around 100,000 infants to be born with CRS each year worldwide.
Despite vaccine availability, an estimated 17,865 rubella cases were reported in 78 countries in 2022.
The rubella vaccine contains a live attenuated strain, and a single dose provides more than 95% long-lasting immunity, similar to the immunity induced by natural infection. It is available alone or, more commonly, in combination vaccines such as MR, MMR and MMRV.
Actress Pamela Anderson has opened up about her hepatitis C diagnosis that once made her fear she had only a few years to live, highlighting how dramatically treatment for the viral infection has changed.
Speaking at the 2026 amfAR Gala Venezia during the Venice Film Festival, Anderson recalled being diagnosed with hepatitis C in 2002. She said doctors had told her she had around 10 years to live, describing the diagnosis as a “death sentence”.
Anderson has previously said she contracted hepatitis C after sharing a tattoo needle with her then-husband Tommy Lee. At the time, the diagnosis carried significant uncertainty because effective curative treatments were not yet available. But more than a decade later, Anderson announced that she had been cured of hepatitis C following antiviral treatment.
While some people clear the virus on their own, most people with hepatitis C who do not clear it develop chronic infection. Over time, chronic hepatitis C can cause liver cirrhosis, liver failure and liver cancer.
According to the World Health Organization (WHO), an estimated 47 million people were living with chronic hepatitis C globally, with about 0.9 million new infections occurring each year.
In 2024, approximately 239,000 people died from hepatitis C, mainly due to cirrhosis and liver cancer.

The major breakthrough came with the development of direct-acting antivirals (DAAs). Before these medicines became available, hepatitis C treatment relied heavily on interferon-based therapies, which could involve prolonged treatment and significant side effects and did not cure everyone.
The first interferon-free DAA treatments were approved in 2013 and 2014, marking a major turning point in hepatitis C treatment. WHO says these medicines can cure the infection in more than 95% of people, generally within a short course of treatment.
Unlike older treatments, DAAs directly target the hepatitis C virus and prevent it from multiplying. Treatment is now usually oral, much better tolerated and considerably shorter than earlier regimens.
WHO recommends pan-genotypic DAAs for people with chronic hepatitis C, with treatment generally lasting around 12 to 24 weeks depending on the person's condition.

The transformation in treatment does not mean hepatitis C has disappeared. There is currently no vaccine against hepatitis C, and millions of people remain undiagnosed.
WHO estimates that by the end of 2024, only around 36% of people who had ever been infected knew their diagnosis, while only about 20% of those diagnosed with chronic infection had received DAA treatment. This makes early testing and access to treatment critical.
Anderson's experience also reflects how quickly medicine can change the outlook of a disease. “I’m not a victim, I’m a victor,” Anderson said while accepting the amfAR Award of Courage in Venice.

Just days after questioning whether the state had correctly linked the deaths of two unvaccinated people to the ongoing measles outbreak, US Health and Human Services Secretary Robert F. Kennedy Jr. has acknowledged and accepted that measles caused the death of a six-week-old child in Pennsylvania.
The shift came after Lancaster County Coroner Stephen Diamantoni confirmed that the infant had died from measles. The child was among two people reported by Pennsylvania health officials as having died in connection with the outbreak.
Kennedy had previously questioned the state's reporting and reportedly asked the Centers for Disease Control and Prevention (CDC) to remove the two deaths from its official tally. The CDC subsequently excluded them from its public data while the deaths remained under review.
The case of the six-week-old infant became particularly controversial because initial findings appeared to raise questions about whether measles was the direct cause of death.
According to Coroner Diamantoni, a review of the infant's medical records and clinical information showed that measles was the cause of death. The child had also been diagnosed with a rare congenital condition that made the infant particularly vulnerable to infections.
The other reported death remains more complicated. In that case, a forensic pathologist found that the infant died from a ruptured spleen and did not determine that measles was the cause, although measles was present. Diamantoni also said that the immediate cause of death was a ruptured spleen, which had further complicated the debate.
The coroner had said that he did not believe measles was the cause of death, although measles was listed on the baby's death certificate as a contributing condition.
Kennedy's acknowledgement of the infant's death comes amid a public dispute with Pennsylvania Governor Josh Shapiro.
Shapiro had criticised Kennedy after the federal health secretary questioned the state's reporting of the deaths, arguing that such statements could undermine confidence in vaccination and public health efforts.
Kennedy, meanwhile, accused Shapiro of “hastily politicizing” the deaths and argued that the state had announced them before the investigations were complete.
The dispute has now placed the focus not only on the deaths but also on how measles fatalities are investigated and recorded by state and federal health authorities.

Pennsylvania has been dealing with a major measles outbreak, with hundreds of cases reported and dozens of people hospitalised. State health officials have said the two people who died were unvaccinated.
The controversy comes at a time when measles is resurging in parts of the US, with declining vaccination coverage raising concerns among public health experts.
Measles is highly contagious and can lead to serious complications, particularly in infants and people with weakened immune systems. Vaccination remains the primary method of preventing infection and transmission.
An infected person can spread the virus to around nine out of 10 unvaccinated people who are exposed. Most people recover, but measles can cause serious complications including pneumonia, brain inflammation and death.
