The international public health community was hopeful that polio—the crippling viral illness that previously paralyzed hundreds of thousands of children every year—was almost extinct. But in a concerning twist in 2025, the World Health Organization (WHO) has raised the alarm- polio is back, and eradication hangs in the balance.

In 2020, the world celebrated a milestone—polio was officially eradicated everywhere except two nations. But in the first quarter of 2025, an old nemesis has reappeared. Cases of wild poliovirus are again increasing in Pakistan and Afghanistan, the final two bastions of endemic transmission. Pakistan, which had reported 74 cases in 2024, has already seen 6 new cases this year. Afghanistan is not far behind with 1 reported case.

While the numbers are small in themselves, they portend a worrisome trend in a decades-long fight. Global health professionals point to interruptions of vaccine campaigns—interruptions they say are directly caused by deep reductions in international assistance.

One major factor behind this upsurge is the abrupt interruption of funding support from the United States Agency for International Development (USAID). USAID has long been a pillar of support for vaccination activities in polio-endemic and high-risk areas by financing personnel, logistics, vaccine sourcing, and outreach.

A private memo by Nicholas Enrich, USAID acting assistant administrator for global health, cautions that if these pauses in funding continue, we will witness another 200,000 cases of polio paralysis each year, and hundreds of millions more are at risk of being infected. The International Rescue Committee (IRC), which was carrying out polio vaccinations under the watch of the Ministry of Health and World Vision in Kenya, says its USAID-funded program was the initial one to close on January 31st.

"Right now, IRC support for polio immunization in Kenya's hard-to-reach areas has come to a halt," confirms Mohamed El Montassir Hussein, Kenya's IRC country director. Although local health officials are still immunizing, their efforts are strained without foreign funding.

Why Does Wild Polio Persist in Just Two Countries?

Pakistan and Afghanistan are the exceptions to an otherwise polio-free world. Several chronic challenges, according to experts, include unstable security environments, misinformation, religious and political opposition to vaccination, and weak health infrastructures. Additionally, vaccination teams working in war zones frequently encounter logistical challenges and safety threats.

The virus has been extremely resilient. It takes advantage of holes in immunity caused by lack of vaccinations. Adding to the problem is the presence of circulating vaccine-derived poliovirus (cVDPV)—an uncommon event whereby the attenuated virus contained within oral polio vaccines changes and becomes virulent again.

WHO Flags High-Risk Nations and Rising Global Concern

The WHO has listed five countries with the immediate risk of the international spread of polio:

• Afghanistan
• Pakistan
• Mozambique
• Democratic Republic of Congo
• Guinea

Furthermore, 35 nations have recorded imported cases of cVDPV type 2, while 10 countries continue to experience active circulation of wild-type or vaccine-derived poliovirus in the last 24 months. WHO's guidelines are:

• Improved vaccine coverage
• Increased access to healthcare in risk areas
• Travel restrictions for unvaccinated travelers from high-risk areas

But with more than $200 million in donor funding lost— including life-saving funds from the U.S. President's Emergency Plan for AIDS Relief (PEPFAR)—these guidelines encounter tremendous implementation challenges.

Hidden Cost of Underfunding Global Health

It is the invisible spread that makes the situation more threatening. Those countries with weak surveillance systems may not see early outbreaks until it becomes too late. In politically unstable or humanitarian crisis-affected areas, the virus can spread quietly among unvaccinated groups, only to spill over borders.

Polio flourishes in these crevices—between the unvaccinated, the untracked, and the neglected. And once it establishes itself, retaking control is that much harder and costly.

Although the numbers as they stand are alarming, they also create an opportunity for recommitment on a global scale. Global polio eradication has always been a collective endeavor. Today, more than ever, a concerted effort is needed.

WHO Director-General Dr. Tedros Adhanom Ghebreyesus reacted with strong concern over the diminishing U.S. support and asserted the urgency for international collaboration. "The precipitous cuts to U.S. funding also affect efforts to stop polio for good," he cautioned.

Relaunching public confidence in vaccines, maintaining secure access during times of conflict, reinstating funds channels, and reinforcing surveillance form part of the arsenal necessary to complete the mission against polio.

The resurgence of polio in 2025 is a wake-up call. It reminds the world that public health victories, no matter how close, can unravel quickly without consistent investment and collaboration.

Eradiating polio was never a matter of one country or one continent. It was about a shared global commitment. If the trend continues, we will risk wasting decades of progress—and allowing a preventable disease to reassert its hold on the world's most vulnerable.

As summer temperatures continue to rise, a quiet terror is making life more miserable by the day for millions- hay fever. Affecting one in four adults and one in ten children in England alone, but this common allergic reaction has reached new heights in 2025, prompting health authorities up and down the UK to sound alarm. With the Met Office forecasting perilously high pollen levels in a number of areas, including London, the North West, and the West Midlands, victims are preparing for a bad season of sneezing, itching eyes, and clogged sinuses.

Hay fever, or allergic rhinitis, is the overreaction of the immune system to pollen—a powdery dust emitted by trees, grasses, and weeds. Although the condition is most often caused by pollen in warmer weather, other allergens such as dust mites, mold spores, and animal dander can trigger symptoms. The result is a mix of misery: runny noses, sore throats, watery eyes, headaches, and even fatigue.

There are more than 30 varieties of pollen that can trigger hay fever, and many people are allergic to more than one. Tree pollen usually hits first (late March to mid-May), with grass pollen (mid-May to July) and then weed pollen (late June to September) in last order.

Why 2025 Is a Record Year for Hay Fever?

The Met Office says that 2025 has enjoyed an "exceptionally high" level of tree pollen, worsened by last year's good weather and sustained warmer conditions this year. The pollen is highest in early evening on sun-kissed days and also strengthened by windy weather, which disperses the pollen, with rain temporarily keeping it down. This renders more people with more intense symptoms, particularly in urban areas where pollutants can synergistically enhance allergic responses.

3 Everyday Triggers Making Hay Fever Worse

1. Outdoor Activities During Peak Pollen Periods

One of the most common culprits? Being outside during the peak pollen periods. Pollen levels usually are the greatest in the early evening, especially on dry, sunny days. Even short exposure can make sensitive people develop symptoms. Specialists advise planning outdoor activities for early morning or after a rain shower when pollen is reduced.

2. Bringing Pollen Indoors

You may think you’re safe inside, but pollen easily travels on clothes, shoes, pets, and even laundry. Drying clothes outside, allowing pets on furniture, or leaving windows open all invite pollen into your living space. To reduce exposure, NHS England advises showering and changing clothes after being outside, keeping windows closed, vacuuming regularly, and using HEPA filters in air conditioning systems and vacuums.

3. Using Unregulated Medications

In a last-ditch attempt at relief, some hay fever patients seek out unlicensed or black-market medication such as Kenalog injections, which are more commonly purchased online. Health authorities warn this strongly against. Kenalog is a prescription-only steroid with severe side effects such as high blood pressure, severe stomach pain, and mood swings. Opt instead for medically approved antihistamines, nasal sprays of corticosteroids, and seek advice from a pharmacist or GP for safe treatment.

Keeping Day-to-Day Symptoms Under Control

NHS England provides a variety of practical tips to cope with the symptoms. Protective actions such as applying petroleum jelly around the nostrils, wearing wraparound sunglasses, and staying away from grassy fields may substantially limit exposure. Although there is no cure for hay fever, regular use of antihistamines and nasal sprays can effectively control symptoms for most.

Steer clear of known irritants like smoking, newly cut grass, and indoor flowers. Preparing the home with air purifiers and allergy-proof bedding can also bring extra relief.

Will Hay Fever Symptoms Continue to Worsen?

Sadly, yes. Global warming is a significant cause for prolonged pollen seasons and enhanced allergen potency. Warmth results in earlier flowering and extended growing seasons, which subsequently result in longer exposure to pollen. Scientists indicate that if environmental trends in recent years continue, hay fever will become even more prevalent and worse in the future.

This year's record-high pollen levels are a blunt reminder that hay fever is no mere seasonal nuisance but a significant medical issue for millions of people. Knowing what aggravates symptoms—and how to evade or treat the culprits—can make an enormous difference. As summer wears on, staying up to speed and taking preventative measures can have you breathing more easily.

If your symptoms are severe or persistent, it’s crucial to seek professional medical advice rather than self-medicating. A tailored treatment plan could drastically improve your quality of life during allergy season. Hay fever might be worse than ever this year, but with the right precautions, it doesn’t have to ruin your summer.

With a global estimate of 20 million cases in 2022, cancer is the leading cause of death worldwide. Cancer diagnoses can turn people’s lives upside down, as the diagnosis is followed up by treatments such as chemotherapy, immunotherapy, or even surgeries. The best way to deal with cancer is catching it early, however the chances of catching it early are very low. Many people only visit their doctors when they see concerning symptoms, but that could also mean that the cancer has progressed much further, reducing the chances of survival.

A new small pilot study suggests that a type of blood test could potentially find signs of cancer up to three years before it would typically be diagnosed. These tests, called multicancer early detection (MCED) tests, look for tiny bits of genetic material that tumors release into the bloodstream.

How the MCED Test Works

This special MCED test works by looking for what's called "tumor DNA" in your blood. Tumors, which are growths of cancer cells, shed little pieces of their genetic material into your bloodstream. The test is designed to pick up on these tiny clues. In the study, it actually found this cancer DNA in some people's blood up to three and a half years before they were officially diagnosed with cancer.

Researchers from Johns Hopkins, said that finding cancer this early could lead to much better results for patients. It's like getting a head start on fighting the disease. They also mentioned that we'd need to figure out the best way to follow up with someone if this test came back positive so early.

Early Findings from the Pilot Study

For this initial study, the researchers looked at blood samples that were already collected for a big heart disease study. They used the MCED test on two groups: 26 people who were diagnosed with cancer within six months of giving their blood, and 26 similar people who didn't get cancer.

The results were quite telling: eight of the 52 blood samples came back positive on the MCED test. And sure enough, all eight of those people were diagnosed with cancer within just four months of their blood sample being taken. The types of cancers found included colon, pancreatic, rectal, lung, breast, and liver cancer. Sadly, five of these eight patients later passed away from their cancers. This shows how serious these diseases are, even when found relatively early.

Uncovering Cancer Even Earlier

To push the boundaries even further, the researchers looked at older blood samples from six of those eight patients. These samples were taken a remarkable three to three and a half years before their cancer diagnosis.

They found tumor DNA in four of those much older samples! This strongly suggests that these cancers could have been spotted years earlier, which could have given doctors a significant head start on treatment. Researchers explained that this study really shows how promising MCED tests are for finding cancers very early. They believe it sets a new standard for how sensitive these tests need to be to truly be successful.

More Research and Enhanced Sensitivity

While these findings are very exciting, it's important to remember this was a small pilot study. We need much bigger studies to confirm these results. However, the initial findings strongly suggest that this type of blood test could be a game-changer, helping us catch cancers when they are much smaller and easier to treat, increasing the chances of survival.

The researchers also pointed out that their main goal was to show how early cancer DNA can be detected in the blood, not just to prove a new test works. They also noted that to find cancers three or more years before a diagnosis, these blood tests will need to be 50 times more sensitive than the ones currently used to detect cancers within six months.

Auto-Brewery Syndrome, also known as gut fermentation syndrome, is a rare medical condition where the digestive system produces alcohol internally. This happens when certain microorganisms—mostly yeasts like Candida or some bacteria—ferment carbohydrates in the gut, creating ethanol. The ethanol then enters the bloodstream, causing symptoms such as dizziness, disorientation, fatigue, and even slurred speech, mimicking alcohol intoxication.

How Does It Happen?

ABS typically occurs when the natural balance of the gut microbiome is disrupted. This disruption can follow antibiotic use, gastrointestinal infections, or diets high in refined carbohydrates. In some cases, people with diabetes or existing gut disorders are more prone to developing the condition.

When the gut environment changes, fermentative microbes may flourish. These microbes thrive on simple carbohydrates and sugars, converting them into alcohol during digestion. While most people efficiently digest these foods without any issue, those with ABS experience a build-up of ethanol, leading to unwanted and surprising symptoms.

The Role of Bread and Carbohydrates

Bread—especially white or refined varieties—is rich in simple carbohydrates. For most people, eating bread in moderation doesn’t cause harm. In fact, whole grain bread can be beneficial due to its fibre content, which supports healthy digestion and feeds good gut bacteria.

However, when eaten in excess, particularly in its refined form, bread can contribute to an overgrowth of fermentative microbes in susceptible individuals. This can lead to symptoms like bloating, gas, discomfort, and, in rare cases like ABS, internal alcohol production.

A Simple Remedy: Psyllium Husk

To support gut health, many wellness experts recommend incorporating psyllium husk, or Isabgol, into your routine. Psyllium is a soluble fibre that absorbs water and forms a gel-like substance in the gut. This helps regulate bowel movements, slows down carbohydrate absorption, and may prevent the rapid fermentation of food in the intestines.

By stabilizing digestion and reducing the speed at which carbs are broken down, psyllium can help minimise gas, bloating, and the risk of ethanol build-up—making it a helpful tool for those concerned about gut health.

Supporting a Healthy Gut

Managing ABS or preventing gut issues doesn't require drastic changes. Here are a few everyday habits that support better digestion:

• Limit intake of refined carbohydrates and processed foods
• Choose whole grains, fresh fruits, vegetables, and lean proteins
• Include fermented foods like yogurt, kefir, or pickles
• Stay active and hydrate well
• Manage stress through breathing exercises, meditation, or regular routines

Auto-Brewery Syndrome is an unusual and extreme case, but it highlights a powerful truth: the food we eat shapes our internal health in surprising ways. Paying attention to our gut and making mindful dietary choices can go a long way in supporting not just digestion, but overall well-being.
