On Thursday, Uganda confirmed an outbreak of the Ebola virus in its capital city Kampala, with the first confirmed patient dying from it a day before. As per the new developments, the officials are now preparing to deploy a trial vaccine to put an end to this outbreak.

Groups of scientists are working on the vaccine and deployment of more than 2,000 doses of a candidate vaccine against the Sudan strain of Ebola has been planned and confirmed by the Uganda Virus Research Institute. As per the World Health Organization (WHO), Uganda has access to 2,169 doses of trial vaccine. For now, however, there are no approved vaccines for the strain and officials are still investigating the source of the outbreak.

The WHO had also allocated $1 million from its contingency fund for emergencies to support quick action and contain the outbreak in the country.

Confirmed Case

On Wednesday, the Sudan strain of Ebola killed a nurse employed at Kampala's main referral hospital. It is after his death that Ebola was declared an outbreak in the country. Post-mortem samples too have confirmed the Sudan Ebola Virus Disease and at least 44 contacts of the deceased man have been listed for tracing. 30 of these are health workers.

Ebola is a highly infectious hemorrhagic fever, which is transmitted through contact with bodily fluids and tissue. Symptoms include headache, vomiting of blood, muscle pains and bleeding.

it was in the late 2022, when Uganda had last suffered an Ebola outbreak. It killed 55 of the 143 people who were infected and was declared over on January 11, 2023.

What Is Ebola Virus Disease?

As per the WHO, Ebola virus disease (EVD) is a rare but severe illness in humans and is often fatal. People can get infected with the virus if they touch an infected animal when preparing food, or touch body fluids of an infected person such as saliva, urine, faeces or semen, or things that have body fluids of an infected person like clothes or sheets.

How Does Transmission Work?

Ebola enters the body through cuts in the skin or when one is touching their eyes, nose or mouth. Early symptoms include fever, fatigue and headache.

It was first discovered in 1976 in two simultaneous outbreak, when in Nzara, South Sudan and other in Yambuku, Democratic Republic of Congo. The latter occurred near a village near the Ebola River, which is where it gets its name from.

It is highly infectious and transmissible disease, in fact, there have been cases of health-care workers who have frequently been infected while treating patients with suspected or confirmed Ebola. This occurs through close contact with patients when infection control precautions are not practiced strictly.

Cases of people conducted burial ceremonies, involving direct contact with the body of the deceased too can lead to the transmission of Ebola. Even after the long suffering and recovery, there is a possibility of sexual transmission. Pregnant women who get acute Ebola and recover may still carry the virus in their breastmilk, or in pregnancy related fluids and tissues.

Symptoms:

• feeling tired
• headache
• muscle and joint pain
• eye pain and vision problems
• weight gain
• belly pain and loss of appetite
• hair loss and skin problems
• trouble sleeping
• memory loss
• hearing loss
• depression and anxiety

A few extra minutes during an upper gastrointestinal endoscopy may help doctors detect more gastric cancers and precancerous alternations, according to research recently discussed at the World Congress of Gastroenterology (WCOG) 2026 in New Delhi.

At WCOG, it was discussed that the quality and duration of an endoscopic examination can influence the chances of finding early cancer. An inspection time of an additional at least seven minutes was linked with about 3.4 times higher detection of gastric cancer and dysplasia.

The finding comes as gastrointestinal cancers continue to increase, contributing to a growing global health burden. GI cancers currently account for around one in four cancer cases and one in three cancer deaths worldwide. The overall burden of the disease is projected to nearly double by 2050.

Dr. Pramod Garg, Professor & Head, Department of Gastroenterology and Human Nutrition, AIIMS, New Delhi; President, Indian Society of Gastroenterology and Co-Chair, Steering Committee, WCOG 2026, said, “Earlier detection depends on both identifying people at risk and ensuring that diagnostic procedures are performed to the highest possible standard. High-quality endoscopy can create an important opportunity to identify disease at a stage when intervention can make a greater difference.”

Could Endoscopy Time Affect Cancer Detection?

An upper gastrointestinal endoscopy allows doctors to examine the lining of the oesophagus, stomach, and upper part of the small intestine using a flexible camera device.

Simply inserting the scope and looking quickly may not be enough to identify subtle abnormalities. A more systematic examination allows the endoscopist more time to examine the stomach lining, identify suspicious areas, improve mucosal visualisation and document findings accordingly.

The WCOG discussion therefore puts focus on not just whether endoscopy is performed, but also on how long and how well it is performed.

The reported 3.4 times association highlights the value of a careful, detailed examination that could help detect changes related to cancer early, prompting timely treatment.

India's GI Cancer Burden

The changes in India's gastrointestinal cancer burden were also discussed, including growing concern around early-onset colorectal cancer. Researchers are examining whether genetics, environmental exposures and changes in the gut microbiome could be contributing to colorectal cancer appearing at younger ages.

WCOG 2026 also included concerns related gallbladder cancer, liver cancer and the rising role of metabolic risk factors. Discussions also focused on the use of AI in gastrointestinal diagnosis and the importance of validating these tools before introducing them in standard practice.

Dr. Govind Makharia, Professor, Department of Gastroenterology and Human Nutrition, AIIMS, New Delhi and Chairman, Local Organising Committee, WCOG 2026, said, “AI has the potential to strengthen diagnosis and decision-making across gastroenterology, while advanced endoscopy is expanding what can be treated through minimally invasive approaches. The next step is ensuring that these technologies are supported by robust evidence and integrated responsibly into clinical practice.”

H. pylori was also addressed as a preventable risk factor for gastric cancer.

Dr Barry Marshall, Nobel Laureate in Physiology or Medicine, said, “H. pylori is much more than an ulcer organism. If the infection persists for many years, it can cause chronic inflammation in the stomach and increase the risk of gastric cancer. That gives us an opportunity because this is a potentially preventable cause of cancer.”

Advances in minimally invasive procedures like POEM, endoscopic submucosal dissection and therapeutic EUS were also discussed, although access to advanced GI care remains uneven.

The President of the United States, Donald Trump, has revealed that he takes aspirin every day, sharing that he has been doing so for decades because he believes it helps keep his blood “thin”.

He said it while discussing his aspirin use and the bruising that was recently seen on his knuckles. He also said that doctors have advised he take a lower dose.

“I take an aspirin a day. I don’t know if it works but psychologically I need it. It thins the hell out of your blood I guess. I don’t know if it works or not but I’ve been doing it for a long time. And here I am making speeches. I like Bayer aspirin. And I take the big one. They want me to go down to the 80. I take the 386. I don’t know what the hell it is. It’s a monster. They said, ‘Sir, you don’t need that!’ I said, do me a favor, I’ve been doing okay for 35 years. Leave me alone.”

So, does taking an aspirin every day actually protect the heart? And if yes, does a higher dose necessarily provide better results?

Aspirin Reduces Blood Clot Formation

Aspirin affects platelets, which are tiny components of blood that help form clots. By making platelets less likely to clump together, aspirin can reduce the formation of blood clots that could block an artery supplying the heart or brain.

This is why doctors may prescribe daily aspirin to people who have already had a heart attack, stroke, or procedures like coronary stent placement.

But aspirin does not make the blood “thin” in a literal sense. It changes the way blood platelets clot. The US Food and Drug Administration (FDA) says daily aspirin can help people with cardiovascular disease or those who have already had a heart attack or stroke, but daily use is not suitable for everyone.

Aspirin can reduce the risk of certain blood clot formations, but it can also increase the risk of unwanted bleeding. The FDA warns that aspirin can lead to serious side effects like bleeding in the stomach and brain.

It recommends that people do not take daily aspirin without discussing it first with their healthcare professionals.

Mayo Clinic also says that daily aspirin is not right for everyone. Regular use can increase the risk of gastrointestinal bleeding and stomach ulcers, while in some people it can also increase the risk of a bleeding stroke.

Who Should And Shouldn't Take It?

For people who have never had a heart attack or stroke or any other type of cardiovascular disease, taking aspirin routinely to prevent a cardiovascular event is generally not recommended.

The American Heart Association says routine daily aspirin is not recommended for most healthy adults without cardiovascular disease because its benefit can be offset by the risk of serious bleeding.

The FDA also says that for people without cardiovascular disease risk, the risks of long-term aspirin use may be greater than the benefits.

For someone who has already had a heart attack, stroke or any other cardiovascular event, doctors may prescribe daily aspirin because preventing another clot-related event can outweigh the bleeding risk.

According to Mayo Clinic, this is a secondary method of prevention. It says that the benefit of daily aspirin in this group is well established. This does not mean that patients should start, stop or change their aspirin dose on their own.

Is A Bigger Aspirin Dose Better For Heart?

A higher dose does not automatically provide better protection against heart attacks. Low-dose aspirin prescribed for cardiovascular health is usually around 75 to 100 mg, with 81 mg frequently used.

Mayo Clinic says that the appropriate dose depends on the individual and should be discussed with a healthcare professional.

Taking higher doses of aspirin can increase the risk of bleeding. People with a history of stomach ulcers or gastrointestinal bleeding, bleeding disorders or aspirin allergy may also face greater risks.

The risk of bleeding also increases with age. The American Heart Association says routine aspirin for primary prevention is generally not recommended for healthy adults over 70.

According to the World Health Organisation, the global life expectancy has recovered to almost pre-pandemic levels, a significant public achievement, but the world is facing a growing burden from chronic diseases,

WHO's latest health estimates, which released recently, offer a glimpse into the pattern of life expectancy and disease burden between 2000 and 2023. It also says that while damages due to COVID-19 have been reversed, the world is grappling with a growing burden of noncommunicable diseases (NCDs).

Global Life Expectancy Is Almost Back To 2019 Levels

Global life expectancy reached 73.3 years in 2023, compared to 73.4 years in 2019, just before the COVID-19 pandemic hit. However, the pace at which healthy life expectancy has recovered has been slow and steady. It stood at 62.8 years in 2023, which was still 0.4 years below the 2019 level.

This means people are living almost as long as they were before the pandemic, but the number of years they can expect to live in good health has not fully recovered.

Dr Alain Labrique, Director of WHO’s Department of Data, Digital Health, Analytics and AI said, "Living longer is one of the great achievements of public health. The next challenge is to ensure that those additional years are lived in good health, while health systems are equipped to respond to the changing needs of populations."

NCDs Account For 74% Of Global Deaths

The WHO data also depicted a growing share of deaths caused by NCDs. In 2023, NCDs accounted for 74% of all deaths globally, compared to 58% in 2000.

In fact, eight of the world's 10 leading causes of death were NCDs in 2023. These include cardiovascular diseases, cancer, diabetes and chronic respiratory diseases.

The change is not limited to wealthier countries. The shift in NCD-related deaths was visible across all income levels.

In 2023, for the first time, communicable diseases accounted for less than half of all deaths in low-income countries, showing how disease patterns are changing even in populations that have traditionally carried a higher burden of infectious diseases.

Heart Disease Remains The World's Biggest Killer

Cardiovascular disease continues to be the leading cause of death worldwide. Ischaemic heart disease alone caused about 9.5 million deaths in 2023, along with an estimated 210 million disability-adjusted life years, a measure that combines years lost because of premature death and years lived with disability.

While there has been progress in reducing the burden of ischaemic heart disease in many parts of the world since 2000, the WHO noted increases in individual-level cardiovascular risk in the South-East Asia and Western Pacific regions.

This highlights continuing differences in cardiovascular health between populations.

Diabetes And Dementia Also Among Major Contributors

The WHO estimates point to growing concerns around other chronic conditions like diabetes and dementia. The risk of dying from diabetes has increased substantially since 2000, especially in South-East Asia.

Dementia has also landed among major causes of death globally. Alzheimer disease and other dementias became the fifth leading cause of death worldwide in 2023, compared to 19th in 2000. Global deaths from dementia tripled between 2000 and 2023, according to the WHO.

Mental Health Adds To The Burden

Between 2019 and 2023, the global age-standardised DALY (disability-adjusted life year) rate increased by approximately 20% for depressive disorders and nearly 45% for anxiety disorders. Together, these conditions were responsible for an estimated 110 million years of healthy life lost through premature death and disability in 2023.

Drug use disorders have also been observed across different trends across regions. Between 2000 and 2023, the WHO Region of the Americas recorded the largest increases in the risk of death linked to these disorders, while the Western Pacific region saw declines.

In a nutshell, the world has largely recovered the ground lost in overall life expectancy during the pandemic. But simply living longer does not necessarily mean we are living healthier. As populations age and infectious diseases account for a smaller share of deaths in many regions, health systems are increasingly required to manage conditions that often need long-term prevention, diagnosis, treatment and care.

“The value of these estimates is not only in the numbers themselves,” said Dr Labrique. “By showing how causes of death and disease burden are changing over time and across populations, they give countries evidence to help shape health policies and priorities.”

“These capabilities are critical to better enable targeted, effective interventions and ultimately further improving health and well-being for all.”
