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.

The Philippines has launched a fresh measles-rubella vaccination campaign in Eastern Visayas, aiming to vaccinate more than 445,000 children aged six to 59 months.

The intensified Measles-Rubella Supplemental Immunization Activity (MR-SIA) will run from August 10 to 28, with support from local governments, schools, community health workers and barangay officials.

The campaign comes as the country continues to recover from years of declining routine childhood immunisation, which left thousands of children at risk to vaccine-preventable diseases.

"Knowing that our past accomplishments in the country are not that high, the Department of Health decided to have an additional layer of protection for our children by coming up with the Measles-Rubella Immunization Activity," said Dr Exuperia Sabalberino, Regional Director of the Department of Health Eastern Visayas Center for Health Development.

According to the Department of Health (DOH), Leyte accounts for the largest target population, with more than 152,000 eligible children, while Biliran has the smallest.

Children under five years of age will be offered the vaccine regardless of their previous vaccination status if they fall within the campaign's eligibility criteria.

About The Campaign

Health authorities have been race to close immunity gaps and prevent new outbreaks of the highly contagious disease.

The latest push follows concerns over low routine immunisation coverage in several Philippine regions. During the 2023 MR-SIA campaign, Eastern Visayas achieved only 72.6% vaccination coverage, well below the level needed to maintain herd immunity.

Health officials warn that insufficient coverage increases the risk of measles and rubella outbreaks. "Vaccination is an extra layer of protection and also prevents outbreaks, as measles and rubella are highly contagious because one confirmed case can affect 12 to 18 people, especially those who are vulnerable and immunocompromised," said Chiradee R. Claridad, DOH-8 National Immunization Program Coordinator.

Measles Remains A Global Concern

Measles is among the world's most infectious viral diseases, spreading through respiratory droplets when an infected person coughs or sneezes.

It can lead to serious complications including pneumonia, brain inflammation, blindness and death, particularly in young children. Rubella is generally milder but can cause severe birth defects if a pregnant woman becomes infected.

The Philippines has experienced several major measles outbreaks in recent years, including the nationwide resurgence in 2019 and the Bangsamoro outbreak in 2024, both linked to poor vaccination coverage.

The Philippines has already made progress in recent months. Last month, the DOH announced that over one million children in Metro Manila had been vaccinated, achieving 87.1% coverage under the measles-rubella campaign.

The latest campaign also comes after measles gained global attention after several countries, including the United States and parts of Europe, reported outbreaks this year driven by falling childhood vaccination rates.

The United States has reported 2,371 in 2026m according to the latest data from the Centers for Disease Control and Prevention (CDC). Among these cases:

• 20% of cases are in children under 5; 49% are in those 5–19 years.
• 7% of patients have been hospitalized, compared with 11% in 2025.
• No deaths have been reported.
• 93% of cases are in people who are unvaccinated or have unknown vaccination status.

The Democratic Republic of Congo (DRC) is battling two public health crises at once. While the rapidly expanding Ebola outbreak has sparked global health emergency, health experts warn that another crisis is unfolding quietly: a sharp rise in maternal deaths as pregnant women avoid hospitals out of fear of infection.

According to the United Nations Population Fund (UNFPA), maternal deaths in Ituri province, the epicentre of the outbreak, have nearly doubled since late May.

Between May 25 and July 19, 2026, the weekly maternal deaths increased from an average of 3.1 to 5.8, while deaths occurring outside health facilities also rose significantly.

Rising Maternal Deaths In DR Congo During Ebola Outbreak

One of the biggest reasons rising maternal deaths in Congo is fear. Many pregnant women have stopped attending antenatal appointments because early Ebola symptoms, such as fever, weakness, and body aches, can resemble pregnancy-related illnesses. They worry they could be wrongly identified as Ebola patients and isolated from their families.

A recent Associated Press report shed light on ground reality by bringing forward the case of Esther Lutula, a pregnant woman from Bunia, who stopped visiting health centres after hearing reports of patients being isolated.

Like many expectant mothers, she chose to stay home despite understanding the risks of pregnancy complications.

"No woman should die giving life because she is afraid to seek care," said Noemi Dalmonte, Deputy Country Representative for UNFPA in the DRC, noting that misinformation and fear are preventing women from accessing essential and lifesaving maternal services.

Health System Under Pressure

The Ebola response in DR Congo has pressurised an already fragile healthcare system. Health workers have been reassigned to work on outbreak control, while others have died, fled conflict, or gone unpaid.

Some health facilities have also faced attacks, disrupting routine maternity care. Surveillance teams continue to struggle with staff shortages, delayed reporting, and limited resources, making it harder to provide essential health services beyond Ebola treatment.

The World Health Organization (WHO) says the current outbreak, caused by the Bundibugyo strain of Ebola, is spreading in a difficult humanitarian setting marked by insecurity, population movement, and limited healthcare access.

Unlike earlier outbreaks, there is currently no approved vaccine or specific treatment for this strain, although vaccine trials are underway.

Why Pregnancy Is Even More Risky During Ebola?

In some previous outbreaks, more than 90% of infected pregnant women died. Delays in treating common obstetric emergencies, like severe bleeding, infections, or obstructed labour, further increase maternal mortality.

Health experts stress that many of these deaths are preventable if women receive timely pregnancy care and better clinical services during delivery.

DRC Ebola Outbreak

The DRC's Ebola outbreak has already become the world's second-largest on record, with more than 3,500 reported cases and over 1,500 deaths.

However, organisations warn that other indirect casualties, including maternal deaths, could increase dramatically if routine health services continue to crumble.

UNFPA is urging governments and humanitarian partners to strengthen maternity services alongside Ebola control efforts, restore community trust, and ensure that pregnant women can safely access healthcare without fear. "The fear of Ebola should not become another cause of maternal death," the agency has warned.

NBA star Kevin Love has once again opened up about mental health, saying the late actor Robin Williams transformed the way he understands depression by showing that the condition often stays hidden until its too late.

Speaking during a recent conversation about mental health, Love reflected on Williams' life and legacy, saying his death challenged the common belief that depression is often evident on people's faces.

"You would have thought that's not a face of depression," Love said, explaining that Williams helped him realise that people can appear joyful, successful, and full of life while silently battling emotional distress.

Love, one of the most prominent athletes advocating for mental health awareness, said the experience reinforced an important lesson: depression cannot be judged by outward appearances.

Depression Doesn't Always Look Like Depression

Mental health experts have long warned that depression is an invisible illness. While some people experience persistent sadness, others continue working, socialising, and smiling despite struggling internally.

This is one reason the condition often goes unnoticed by family, friends, and even healthcare providers.

Love's remarks reflect his own journey. After experiencing a panic attack during an NBA game in 2017, he began speaking publicly about anxiety and depression, encouraging others to seek help instead of suffering in silence.

In a previous essay, he wrote, "You would be amazed at how freeing it is just to talk to somebody, and tell them the truth about what you're going through," adding that "it does get better."

Recognising The Symptoms

According to mental health experts, depression is more than feeling sad for a few days. It comes with a bunch of symptoms that often get neglected. Common symptoms include:

• Changes in mood: Persistent feelings of sadness, irritability, or apathy can be indicative of depression or anxiety.
• Loss of interest: Decreased enjoyment in activities that were once pleasurable is a common sign of mental health struggles.
• Difficulty concentrating: Problems with focus, memory, or decision-making can significantly impact daily life.
• Changes in sleep patterns: Insomnia, excessive sleep, or disrupted sleep may be related to underlying emotional distress.
• Withdrawal from social activities: Isolating oneself from friends and family can be a sign of deteriorating mental health.

It's important to note that these are general indicators, and individual experiences may vary. If you or someone you know is experiencing persistent symptoms, seeking professional help is crucial.

Symptoms vary from person to person, and many individuals may not openly express what they are experiencing.

Love said Robin Williams changed his perspective because his story challenged stereotypes surrounding depression. His message serves as a reminder that mental health conditions do not discriminate based on fame, success, or personality.

By continuing to share his own experiences, Love hopes more people will feel comfortable asking for help and checking in with those around them.

His words also reinforce an important public health message: emotional struggles are not always visible, making compassion, open conversations, and early support essential for recognising depression before it becomes a crisis.
