About a third of US adults say they lie to their doctors to get antibiotics, a behavior that may promote the growth of antibiotic resistance.

The overuse and misuse of antibiotics are significant contributors to the rise of antibiotic resistant bacteria. Experts say antibiotics should only be used for specific medical problems, and patients need to be sure to take antibiotics exactly as prescribed in order to reduce the risk of antibiotic resistance.

Antibiotics have long been used in agriculture to treat diseases in animals and plants. However, antibiotics are also often misused, to treat non-bacterial diseases, to encourage growth in animals, and more. This expansive use of antibiotics has become one of the primary sources of the emergence of new superbugs.

Antimicrobial resistance is a global health threat, driven by the misuse and overuse of antimicrobials in humans, animals, and more. Estimates suggest superbugs could lead to $1T in healthcare costs by 2050, and the world faces a shortage of new drug development to meet the challenge.

Since 1990, antibiotic resistance has claimed at least one million lives annually and is projected to account for 39 million deaths between now and 2050 if current trends continue. The expanded use of antibiotics, particularly in agriculture, combined with a slowing pipeline of new drugs has led to the crisis.

The increased use of antibiotics combined with an aging population, is projected to result in an almost 50% increase in global deaths from antimicrobial resistance each year. At the same time, antibiotic use for livestock is expected to increase by 30% over the same time frame.

Antimicrobial resistance is bad news. But there are lots of things you can do to both protect yourself from superbugs and help keep the problem of antimicrobial resistance from getting worse. This page from the CDC offers clear, straightforward guidelines that can help keep you—and your loved ones—healthy.

The COVID-19 pandemic was caused by a virus, and viruses can’t be treated with antibiotics. But recent research finds that COVID patients were given a tremendous amount of antibiotics, contributing to the problem of antibiotic-resistant bacteria. Why? This NPR feature sheds light on an unexpected side effect of the pandemic.

In 2024, researchers published an incredibly detailed study aimed at predicting the real-world impact of antimicrobial resistance over the next 25 years. The key findings were clear: the superbug crisis is poised to get much worse and needs to be addressed. This article offers a clear, concise overview of the study, which was published in The Lancet.

One reason antibiotic resistance spreads so quickly is that bacteria have multiple mechanisms allowing them to share genetic material. This short video offers a concise explanation for each of these mechanisms, and animation that helps viewers understand how antimicrobial resistance can quickly spread from one organism to another.

What does the rise of antibiotic resistance mean in practical terms? Maryn McKenna is a journalist at the forefront of covering antibiotic resistance since 2007. In this TED talk, McKenna lays out the very real consequences of antibiotic resistance—and what needs to be done to address the problem.

The vast majority of bacterial treatments were developed during the "Golden Age of Antibiotics," an era of rapid innovation and drug discovery that led to the reduction of millions of deaths worldwide. Since 1970, only eight new antibiotic classes have been discovered.

Why don't we just develop new antibiotics? In part, it's a complex scientific challenge, but market incentives also play a significant role. It can be time consuming, expensive, and most notably, we should use as little as possible to avoid driving further antibiotic resistance.

The Canadian journal Paediatrics & Child Health issued corrections to 138 case studies published since 2000, acknowledging the cases were entirely fictional—a practice intended to protect patient privacy that was never disclosed to readers. At least 61 of the fabricated reports were cited as fact in other peer-reviewed journals a combined 218 times, including a 2006 Lancet article alleging an infant died from opioid-laced breast milk.

A US government report indicates that about 10% of US adults took prescription medication for this disorder in 2023. Women, at 15.3%, were more than twice as likely to take one of these medications than the 7.4% of men.

Alexander Fleming’s discovery of penicillin revolutionized modern medicine. But the same man who pioneered the development of antibiotics also recognized that bacteria could make sntibiotics obsolete if they were used irresponsibly. This story sheds light on Fleming’s discovery—and on his prophetic warning about antibiotic resistance.

Antimicrobial resistance has become an increasingly glaring problem for both health and agriculture. In 2024, the United Nations announced a new suite of clear actions and targets that—taken together with existing efforts—can help address superbugs in a meaningful way and on a global scale. This page from the UN lays out these efforts, with links to additional information on the many aspects of the initiative.

Unlike humans, bacteria rapidly make genetic changes in response to their environment, including creating defense against antibiotics. Furthermore, these defenses are passed on to their future generations and can even be shared with neighboring bacteria through horizontal gene transfer.

Research published in 2021 surveyed how more than 100 kids with food allergies were treated by their peers. About one-third of the surveyed kids had their allergies used against them. Bullying tactics included that their allergens were sometimes intentionally put in their food or thrown at them. Parents usually had no idea this bullying was happening.

Superbugs are a very real problem, but researchers around the world are working to advance our understanding of these pathogens and develop new medicines. This podcast talks with several scientists on the frontier of superbug research, offering insight into what we know—and what the future of medicine may look like.

Research published in 2022 suggests that 14.5% of the world's population has contracted Lyme disease. Researchers arrived at that estimate by analyzing the presence of Lyme disease antibodies (indicating prior infection) across 89 studies conducted between January 1984 and December 2021. The works collectively included blood samples from more than 150,000 people.

Research published in 2019 found that almost half of 40,000 surveyed adults with food allergies developed a new food allergy as adults, underscoring that our immune systems may newly misclassify substances later in life.

Peer-reviewed research published in 2025 from Pfizer—a pharmaceutical company working on a candidate vaccine for Lyme disease—examined Lyme data from more than 150,000 Medicare and Medicaid beneficiaries and found that Black patients, as compared to white beneficiaries, were more likely to have disease that had spread further throughout the body at the time of care. The difference, the scientists wrote, may be partly due to difficulties recognizing the characteristic rash on darker-colored skin.

The research published in September 2025 examined differences in Lyme disease diagnosis among Medicaid and Medicare beneficiaries using data from 2016 to 2021. It notes that though US Lyme disease surveillance data indicates more than 90% of diagnosed Lyme cases are among white people, people of color—particularly those who identify as Black or African American—have higher rates of more severe disease of Lyme, with symptoms including arthritis and neurologic impacts.

With that kind of statistic as a backdrop, proponents of concierge medicine practices argue that concierge services could help keep doctors in medicine and thus help to address physician shortages.

GLP-1 drugs popularity for weight loss and treating diabetes, led to a significant supply shortage and the rise of compound pharmacies, which produce customized drug formulations but lack formal approval from regulators. The drugs are ostensibly the same, but manufacturing methods lead to variations in concentration, filler compounds, and more.

The origins of the US' ongoing opioid crisis are typically traced to the more than 1 billion prescription pain pills that flooded medicine cabinets between 2005 and 2019. This prescription opioid epidemic resulted in more than 210,000 fatal overdoses and set the stage for the ongoing crisis fueled by heroin and fentanyl.

The World Health Organization updated its list of the highest priority pathogens known to have developed antimicrobial resistance. Topping the 2024 update is Acinetobacter baumannii, carbapenem-resistant ("CRAB"), which has a mortality rate close to 50% and has evolved defenses against last-line medications.

Explore the data showing how the fungus C. auris has spread in the US, with more than 10,000 reported cases since 2016. Recommended steps to prevent infections and limit their spread have been successful in some areas, but infection control remains complicated because the fungus is often now multidrug-resistant.

Physicians, especially in the UK, are asking patients what they enjoy and then prescribing a consistent regimen of doing that type of activity to improve fitness and overall health, including community exercise classes, volunteering, and spending time in nature. This approach may provide better incentives to stick with an activity.
