Silent Tsunami: The Return Of A Killer Germ That No Drug Can Stop
In hospitals across the United Kingdom (England, Wales and Northern Ireland), a pattern has begun to emerge. Not a fluke. Not a seasonal spike. But a steady and quiet surge. The UK Health Security Agency (UKHSA) has reported 702 confirmed cases of typhoid and its cousin, paratyphoid fever, in 2024 alone. That is an 8% jump from the year before. It is the highest count ever seen.
The source is not homegrown. This is not an outbreak tied to any one British city. Most of the infections were picked up abroad. Travellers are bringing it back, unwittingly, after visiting regions where the disease still thrives in water and food. But now there is a new twist – the old treatments no longer work. Typhoid is morphing into something scientists fear – a resistant and borderless predator.
Much of the threat today comes from Pakistan, where doctors are facing a terrifying challenge. The typhoid strain spreading there is no longer afraid of our antibiotics. Not even the newest ones. This strain, now called extensively drug-resistant Typhi or XDR Typhi, does not respond to the usual weapons – ampicillin, chloramphenicol, trimethoprim, fluoroquinolones or even cephalosporins. These used to be life-savers. Now they barely scratch the surface.
A team of researchers led by Stanford's Dr. Jason Andrews studied nearly 3,500 bacterial samples collected from Nepal, Bangladesh, India and Pakistan between 2014 and 2019. What they saw was eye-opening. The number of drug-defiant typhoid strains is growing fast. They are replacing treatable ones. And they are not staying local.
The study revealed something more chilling – these mutated bacteria are on the move. Since 1990, scientists have tracked nearly 200 instances of international spread. Southeast Asia. East Africa. Southern Africa. And now, Western countries. Yes, even in the United Kingdom, the United States and Canada, typhoid superbugs are starting to show up.
Every plane ticket. Every border crossing. Every contaminated sip or bite. The bacteria need only one chance.
Globally, typhoid and paratyphoid infect around 13 million people every year. Over 1.3 lakh people lose their lives, most of them children in Asia and Africa. Despite its scale, typhoid rarely makes headlines. But that silence is dangerous. Especially now.
The only treatment left is oral antibiotics. But their power is fading. Over three decades, the bacteria have gradually built resistance. They have learned. Adapted. And now, they are spreading those learnings across borders.
The UKHSA data is just one part of the puzzle. Researchers say there are large blind spots, particularly in regions like sub-Saharan Africa and Oceania. We simply do not have enough bacterial samples from these places. Even in better-monitored countries, the samples usually come from just a handful of sites. That is like trying to map a wildfire by staring at a single tree.
That lack of information means something troubling – we may be underestimating the scale of resistance and how fast it is travelling. The bacteria's genes and the mutations that make it immune are quietly crossing oceans. And we are not watching closely enough.
Dr. Andrews calls this a 'real cause for concern'. He is not exaggerating. The way these strains have spread shows that typhoid control is a global emergency. Surveillance needs to expand. So do new treatment strategies. And vaccines need to reach where the outbreak begins, not where it ends.
We live in an age of mobility. People, goods and germs travel faster than ever.

Detained UK Couple In Afghanistan Get Medical Care After UN Appeal
An elderly British couple detained for months in Afghanistan are receiving medical care, the Taliban government's top diplomat said Wednesday, after UN experts warned they were at risk of dying. Peter and Barbie Reynolds, 80-years-old and 75-years-old, had lived in Afghanistan for 18 years when they were arrested in February along with Chinese-American friend Faye Hall, who has since been released, and an Afghan translator. "All their human rights are being respected," Afghan Foreign Minister Amir Khan Muttaqi told a news conference in the capital Kabul. "They are being provided with medical care. They are in occasional contact with their families." Muttaqi said "efforts are underway to secure their release, but the process is not complete", echoing similar comments by the government in April. Independent United Nations experts warned on Monday of the "rapid deterioration" of their physical and mental health, stating that they "risk irreparable harm or even death". The couple, against whom no charges have been brought, were held "in a high-security facility for several months, then in underground cells, without daylight, before being transferred last week" to the intelligence services in Kabul, according to the UN. The experts said Peter Reynolds requires heart medication following a stroke in 2023. Since his detention, he has suffered two eye infections and intermittent tremors in his head and left arm. His wife, who is anemic, is "weak and fragile" and has reported numbness in her feet, the experts said. The couple, who married in Kabul in 1970, had been running education programmes in Afghanistan and held Afghan passports. Taliban officials have refused to detail the reasons for their arrest but a source familiar with the case told AFP in April that the couple were in possession of several non-Islamic books.

‘I am a gut doctor and here are 7 things I wish more people knew about fibre'
Did you know that most people aren't getting enough fibre in their daily diet? While it's often overlooked, fibre plays a crucial role in keeping your digestion smooth, supporting weight management, and even improving heart health. Despite its importance, a surprising number of people remain unaware of how fibre affects nearly every aspect of their well-being. Dr Saurabh Sethi, a content creator and gastroenterologist trained at AIIMS, Harvard, and Stanford universities, shared in an Instagram post, seven facts about fibre that everyone should know. Dr Adithya V Naragund, senior consultant in GI and HPB Surgery at Cytecare Hospitals, Bengaluru, helps us decode each of the points in detail: Dr Sethi mentions, 'About 95 percent of Americans don't get enough fibre.' 'Yes, that's quite accurate,' notes Dr Naragund, adding that while this statistic is from the US, 'the trend holds true in India too, especially in urban populations where diets are increasingly processed and refined.' He stresses that a fibre-poor diet can result in sluggish digestion, frequent sugar cravings, and a lack of satiety. These symptoms often get overlooked or misattributed, but they're strong signals from the gut that it's missing this essential nutrient. 'You're eating for trillions of microbes' in your gut, states Dr Sethi. Dr Nagarund says, 'This is a wonderful way to put it. Our gut microbiome thrives on prebiotic fibres that help it function optimally.' When well-fed, he explains that these microbes support not just digestion but also regulate mood, support immune defence, and even influence how we handle stress. The gut truly is a second brain, and fibre is one of its most important fuels. According to Dr Sethi, soluble fibre feeds gut microbes and helps lower cholesterol. Insoluble fibre adds bulk to stool and supports regular bowel movements. 'Yes, both soluble and insoluble fibre play unique roles,' states Dr Nagarund. 'Soluble fibre, found in oats, apples, and beans, helps manage blood sugar and cholesterol. Insoluble fibre, which you get from whole grains and the peels of fruits and vegetables, helps bulk up stool and support regularity. Together, they work in harmony to keep the gut resilient and balanced.' 'High-fibre foods fill you up, slow sugar spikes, and reduce cravings,' notes Dr Sethi, to which, Dr Nagarund adds that research increasingly supports this. Fibre-rich foods are not only more filling but also slow down digestion, which helps curb overeating. 'A steady intake of around 25 to 30 grams per day can lead to better metabolic health, improved insulin sensitivity, and gradual fat loss over time — especially around the abdominal area,' says the doctor. A post shared by Saurabh Sethi (@ Adding fibre too quickly can cause gas, bloating, and discomfort, stresses Dr Sethi. According to Dr Nagarund, this is a key point. 'A sudden jump in fibre intake can backfire, causing bloating or discomfort. A gradual increase, paired with more water and a little movement, helps the body adjust. Everyone's tolerance is different, so it's important to go slow and be mindful,' he says. Dr Sethi writes, 'Lentils, oats, chia, flax, berries, and even popcorn are fibre-rich; you don't have to live on salad.' Concurring, Dr Nagarund details the benefits: 'Pulses, millets, fruits with skin, seeds like flax and chia, and even snacks like air-popped popcorn can be great sources. Traditional Indian foods like sabut dal and the use of whole grains like bajra and jowar already offer rich fibre — when not overly refined.' Dr Sethi explains that it supports brain function, lowers heart disease risk, builds a resilient microbiome. 'Fibre truly is a cornerstone of preventive health. From balancing hormones to reducing heart risk and supporting cognitive clarity, its benefits go well beyond digestion. It helps create a healthy gut ecosystem, which in turn supports many vital functions across the body,' concludes Dr Nagarund.

Contact sports can cause brain injuries. Should kids still play?
Economist , The Economist Modifying rules and grouping players by size rather than age can limit the risks Children play in a new sports hall Gift this article RECENT YEARS have seen a steady drip of troubling studies on head injuries among young players of rugby and American football. Research on schoolboy rugby published in Sports Medicine in 2023, for example, calculated that nearly two concussions result from every 1,000 tackles. As for American football, one in 20 youth players suffers a concussion over the course of a season, per a study in the Journal of Pediatrics. The real risks could be even higher, as many concussions go unreported. RECENT YEARS have seen a steady drip of troubling studies on head injuries among young players of rugby and American football. Research on schoolboy rugby published in Sports Medicine in 2023, for example, calculated that nearly two concussions result from every 1,000 tackles. As for American football, one in 20 youth players suffers a concussion over the course of a season, per a study in the Journal of Pediatrics. The real risks could be even higher, as many concussions go unreported. The consequences can be tragic. If a second concussion is sustained before complete recovery, it is more likely to trigger acute brain swelling, which can be fatal. Younger, developing brains appear more susceptible to such 'second-impact syndrome". Even weaker 'subconcussive" blows to the head are a concern. If repeated for long enough, such hits may damage a brain's white matter, the nerve fibres that transport electrical impulses. A paper published in Brain Communications in 2023 suggests that athletes who were exposed to head impacts from a young age are more likely to experience cognitive decline from subconcussive damage to white matter. Outright bans on youth contact sport are one option. Another is to focus on protective gear. But in rugby, at least, research has yielded surprising results. Padded 'scrum caps" do protect ears and reduce cuts, but neither scrum caps nor helmets can stop a brain from being pushed into the skull, the cause of concussions. Many players are unaware of this, leading to dangerous false confidence and more aggressive play. New types of protective headgear are emerging. In 2022 a British startup called Rezon began to sell a special padded headband for rugby and other sports. Known as Halos, it is composed of nine layers which slide over each other when hit at a non-perpendicular angle. The resulting friction, the company claims, reduces by 61% the transmission of rotational forces to the brain. Rule changes are another solution. Some are hotly contested. Forbidding tackling for minors, for example, may end up increasing injuries when players grow up without having learned the best techniques. The American Academy of Paediatricians, for its part, has declined to endorse a blanket ban. Widespread rules against specific types of impacts including head-first 'spear-tackling", however, have curbed injuries. So have increasingly common policies that limit full contact during practice. Young players can also be grouped differently. Children enter puberty at different ages, which can lead to glaring mismatches in body size and agility. The injury risk to smaller kids is compounded when teams short on players call up older children too. To avoid such risks, young players are increasingly grouped by physical maturity, not age. This 'bio-banding" appears promising, but research remains regrettably thin. Parents who are still concerned should consider two final points. First, any impacts that rough-and-tumble sports may have on mental development could be revealed by periodic cognitive tests. Second, a child prevented from playing rugby or tackle football might well find other dangerous hobbies. A paper published in the Medical Journal of Australia in 2019 reviewed 8,857 children taken to emergency rooms for head injuries and found that recreational activities such as horse-riding, biking and skateboarding caused more serious injuries than contact sports.
