Typhoid fever is not the kind of illness most people in developed nations worry about. It's often written off as a disease of the past—something that plagued ancient societies before clean water systems and antibiotics. But here’s the thing: typhoid never went away. And now, it's evolving into something much more dangerous—something even modern medicine might not be able to stop.
A large genomic study published in The Lancet Microbe in 2022 has sounded the alarm. The bacterium responsible for typhoid, Salmonella enterica serovar Typhi (or S. Typhi), is rapidly acquiring resistance to nearly all antibiotics used to treat it. More disturbingly, strains resistant to multiple drug classes are spreading beyond their traditional strongholds in South Asia and appearing across continents—including in the United States, United Kingdom, and Canada.
This is no longer a regional concern. It’s a global one.
The study involved sequencing over 3,400 S. Typhi strains collected between 2014 and 2019 from patients in India, Pakistan, Nepal, and Bangladesh. The results were stark. Not only were extensively drug-resistant (XDR) strains of typhoid rising rapidly, but they were also outcompeting and replacing less resistant versions.
XDR typhoid strains are already immune to several older antibiotics—ampicillin, chloramphenicol, and trimethoprim/sulfamethoxazole. But here’s where it gets worse: many are now developing resistance to newer and more potent drugs like fluoroquinolones and third-generation cephalosporins, which until recently were mainstays of typhoid treatment.
Even the last reliable oral antibiotic—azithromycin—is showing signs of failure. The study found emerging mutations that could potentially render azithromycin ineffective. These haven’t yet converged with XDR strains, but scientists warn that it’s only a matter of time. If that happens, oral treatment options could become entirely obsolete.
For now, South Asia remains the epicenter of the crisis, accounting for about 70% of the global typhoid burden. But this doesn’t mean the threat is contained.
Researchers tracked nearly 200 instances of international transmission since the 1990s, most involving travel or migration. Typhoid "superbugs" have been detected in Southeast Asia, East and Southern Africa, and in wealthy nations where the disease was thought to be virtually eradicated.
“The speed at which highly-resistant strains of S. Typhi have emerged and spread is a real cause for concern,” said Dr. Jason Andrews, an infectious disease specialist at Stanford University who co-authored the study.
If antibiotics are failing, what’s next? For starters, prevention. Experts say the most immediate and scalable solution lies in typhoid conjugate vaccines (TCVs). These vaccines offer strong, long-lasting protection and are safe for children as young as six months old. But access is patchy.
Pakistan became the first country to introduce TCV into its national immunization program in 2019—an urgent response to the first major outbreak of XDR typhoid that hit its population. Since then, the move has become a case study in how vaccination can cut off the disease at its roots.
India, Bangladesh, and Nepal have followed suit with pilot programs and localized rollouts, but global coverage remains far too low. Meanwhile, high-income countries have not prioritized TCV access at all, largely because typhoid isn’t seen as a domestic threat.
This typhoid crisis isn’t an isolated story. It’s part of a larger, systemic problem: antibiotic resistance is now one of the top global causes of death. A 2019 study published in The Lancet estimated that antimicrobial resistance was directly responsible for 1.27 million deaths worldwide, surpassing HIV/AIDS and malaria.
Typhoid is just the latest face of that threat. If azithromycin fails, intravenous treatments will be the only remaining option. This is not sustainable for low-resource settings, where typhoid is most rampant.
And as the S. Typhi genome continues to adapt, the search for novel antibiotics becomes more urgent but the global antibiotic pipeline is worryingly dry. Very few new drugs are being developed, and those that are rarely target neglected tropical diseases like typhoid.
COVID-19 reminded us how quickly a localized health threat can go global. Typhoid is no different. The bacteria travel with people—through tourism, immigration, and international trade.
The difference is: we already have tools to stop this. TCVs work. Better sanitation and access to clean water help. Public health messaging and travel guidelines can make a difference. But we’re not moving fast enough.
A recent Indian study estimated that vaccinating children in urban areas could reduce typhoid cases and deaths by up to 36 percent. That’s a significant dent—especially when combined with infrastructure upgrades and careful antibiotic stewardship.
If left unchecked, drug-resistant typhoid could become nearly impossible to treat in outpatient settings. That means more hospitalizations, more strain on health systems, more deaths—particularly among children in developing nations.
With around 11 million cases of typhoid annually, even a small increase in resistance could tip the balance into a major health crisis.
And if XDR strains gain resistance to azithromycin, we will be left with zero effective oral drugs, none. The path forward is clear—and urgent. Here’s what needs to happen:
Antibiotic resistance isn’t science fiction. It’s a biological reality. And typhoid is just one example of how quickly things can unravel when we underestimate an ancient enemy.
We can still turn the tide but only if we act with urgency and coordination. The warning signs are flashing red. Typhoid isn’t gone. It’s evolving. And this time, it may be deadlier than ever.
A Class IX student in Kollam was diagnosed with H1N1 (swine flu) on Wednesday. Reports find that three other students from the same class were reporting fever-like symptoms since July 13 and are now being treated for similar symptoms. Currently, their test results are pending. The health officials will now be screening more students at the school.
H1N1 flu, also called "swine flu," is a very catching virus. It mostly affects your nose and throat, but can sometimes get into your lungs too. If you get H1N1, you might feel sick with things like:
While it's often a mild illness, it can sometimes cause serious issues in your lungs or stomach. In rare cases, it can even lead to serious breathing trouble or other infections.
This type of flu became a worldwide problem because it was a new mix of pig, bird, and human flu viruses. It spread to millions of people and even affected businesses like food and tourism.
The best way to fight H1N1 is to get antiviral medicine early, within 72 hours of your symptoms starting. This can make the illness less severe and even save lives. Vaccines and other ways to prevent the flu are also super important to stop it from spreading.
If your doctor thinks you have H1N1, they'll test samples from your nose or throat to be sure. Getting the best care, especially for people who are at higher risk, often involves a team of different healthcare professionals working together.
The Centre of Disease Control and Prevention explains that swine flu is a highly contagious breathing illness that affect pigs. While it's uncommon for humans to catch swine flu from pigs, it can happen if they are in close contact with infected pigs or places where their viruses are present. Once a person gets infected, they can then spread the virus to other people, likely through coughing or sneezing, just like regular seasonal flu.
CDC explains that just like the flu virus that affects people and birds, swine flu viruses are always changing. Pigs are unique because they can catch flu viruses not just from other pigs, but also from birds (avian flu) and people (human flu).
When different types of flu viruses infect a pig at the same time, they can mix and swap their genetic material. This is like shuffling a deck of cards. When they mix, brand new flu viruses can be created that are a combination of swine, human, or avian flu.
Over time, many different kinds of swine flu have appeared. Right now, in the United States, there are three main types of influenza A viruses found in pigs: H1N1, H1N2, and H3N2.
According to Medscape, if you have H1N1 flu, the main goal of treatment is to help you feel better. This usually means resting a lot, drinking plenty of fluids, and taking medicines to calm your cough, lower your fever, and ease muscle aches (like Tylenol or ibuprofen). If someone gets very sick, they might need fluids given through a vein and other help from doctors. Sometimes, doctors might also give special antiviral medicines to treat the flu or to keep you from getting it if you've been exposed.

In Muklawa, Sri Ganganagar district in Rajasthan, nobody even had an idea of what's cooking. Two teachers from a local government school and a physics tutor from a local coaching centre, Manoj Bharghav and Indrijeet Bishnoi, respectively set up a lab to make synthetic drugs like Mephedrone.
Both were inspired by the American series 'Breaking Bad'. They have now been arrested for manufacturing Mephedrone or MD (4-Methylmethcathinone) drug worth Rs 15 crore in Rajasthan, the Narcotics Control Bureau (NCB) said.
Mephedrone (4-methylmethcathinone), as per Alcohol and Drug Foundation, is an ampathogen-stimulant drug, which means it speeds up the messages travelling between the brain and body. Mephedrone also increases an individual’s feeling of empathy and kindness and enhances feelings of being socially accepted and connected to others.
Mephedrone is a New Psychoactive Substance (NPS) - a drug that has been designed to produce effects similar to those of established illicit drugs. It was originally marketed online as a plant fertiliser or 'research chemical'.
Mephedrone comes in different forms:
The drug is also known by other street names like Meph, meow, meow-meow, m-cat, plant food, drone, bubbles, and kitty cat.
It is usually sniffed, snorted, or swallowed. Swallowing is the most common way of taking a drug and it usually is mixed with liquid to drink or wrapped in a cigarette paper.
As per the Alcohol and Drug Foundation, Mephedrone affects everyone differently, based on:
The following effects may be experienced and may last for two-to-four hours:
The two were arrested on the charges of clandestinely running a manufacturing laboratory from their rented flat at Dream Homes Apartment n Riddhi-Siddhi Enclave in Sri Ganganagar. This had been going on for at last two-and-a-half-months. As per the NCB Director Ghanshyam Soni, the duo sourced their chemicals and equipment from Delhi and took leave from their jobs to manufacture it.
The two were able to produce about five kilogram of MD, which was worth 15 crore. Of that, they sold 4.22 kg of drugs, confirmed Soni.
Chemicals like acetone, benzene, sodium hydrogen carbonate, bromine, methylamine, isopropyl alcohol, 4-methyl propiophenone and n-methyl-2-pyrrolidone were seized from their property.

Mitochondrial Disease: In a groundbreaking development in reproductive medicine, researchers in the U.K. announced that eight healthy babies have been born using an experimental technique involving DNA from three people.
The method was developed to help prevent mothers from passing on devastating mitochondrial diseases to their children — conditions that can lead to seizures, muscle weakness, organ failure, developmental delays, and even death.
This scientific milestone was detailed in a study published in the New England Journal of Medicine on Wednesday.
Experts from Newcastle University in the U.K. and Monash University in Australia conducted the procedures, which used a technique known as mitochondrial donation treatment. The technique replaces faulty mitochondria, which are the tiny energy-producing structures in cells, with healthy ones from a donor.
While most of our DNA is stored in the nucleus of our cells and inherited equally from both parents, a small but vital portion resides in the mitochondria and comes solely from the mother. Mutations in this mitochondrial DNA can lead to serious, and often fatal, genetic disorders in children.
During the in vitro fertilization (IVF) process, it is sometimes possible to detect these mutations early. However, in rare cases, such mutations go undetected — which is where mitochondrial donation becomes important.
In this method, scientists transfer the nuclear DNA from the mother's egg or embryo into a donor egg or embryo that contains healthy mitochondria but has had its own nuclear DNA removed. The resulting embryo contains nuclear DNA from the parents and mitochondrial DNA from a donor — essentially, the genetic input of three people.
The U.K. became the first country in the world to legalize mitochondrial donation for clinical use in 2016, after years of ethical and scientific debates. Australia has also approved its use. However, the U.S. still prohibits any clinical research involving genetic modification of human embryos that could be inherited.
“This marks an important milestone,” said Dr. Zev Williams, director of the Columbia University Fertility Center in New York, who was not involved in the study. “Expanding the range of reproductive options will empower more couples to pursue safe and healthy pregnancies.”
As of now, 35 couples have been approved by the U.K.’s fertility regulator to undergo the procedure. Of the 22 patients treated in the reported study, eight babies have been born, and one more woman is still pregnant. Most of the children appear to be free of mitochondrial disease, though one child was found to have a slightly higher-than-expected level of abnormal mitochondria. Experts say this level is not currently cause for concern but will require monitoring.
Despite the involvement of a third person, scientists emphasize that the genetic material from the donor is minimal. Dr. Robin Lovell-Badge, a stem cell expert at the Francis Crick Institute, noted that the donor’s mitochondrial DNA makes up less than 1% of the baby’s total genetic makeup — not enough to influence personal traits like appearance or personality.
“In fact, if you had a bone marrow transplant, you would carry much more of another person’s DNA,” he explained.
The technology remains controversial in some circles. Critics warn that the long-term effects of such genetic manipulation are still unknown and could have unintended consequences for future generations. In the U.S., Congress has repeatedly blocked any government funding or approval of similar research.
Still, for many families, the promise of avoiding a life-threatening diagnosis is worth the risk.
Liz Curtis, whose daughter Lily died of mitochondrial disease in 2006 at just eight months old, now advocates for awareness and research. She founded the Lily Foundation in her daughter's memory and supports the work being done at Newcastle University.
Curtis said the diagnosis devastated her family. “Nobody could tell us what it was or how it would affect Lily. It was just a waiting game,” she recalled. “This new technique gives hope to families who’ve had very little of it.”
As science and ethics continue to evolve, the three-parent baby technique stands as a powerful, if complex, step forward in preventing inherited genetic illness.
