Public health & disease

From disease eradication efforts to advances in vaccination and maternal health, this archive tracks real progress in public health. Stories here focus on what’s working — policies, interventions, and research that are improving and extending lives around the world.

New treatment eliminates insulin for 86% of patients in early trials

By / / Good News For Humankind

A one-hour outpatient procedure helped 12 of 14 Type 2 diabetes patients stop using insulin entirely and stay off it for a full year. Researchers at Amsterdam University Medical Center used a catheter to deliver gentle electrical pulses to the lining of the small intestine, prompting the tissue to regenerate and apparently restoring the body’s natural insulin response. By comparison, the widely used medication semaglutide alone helps only about one in five patients discontinue insulin. The team calls the approach “disease-modifying” because it targets the root cause rather than the symptoms, and a larger randomized trial is now in the works. If the results hold, it could reshape how a condition affecting hundreds of millions worldwide is treated.

New cervical cancer treatment regime ‘cuts risk of dying from disease by 40%’

By / / Good News For Humankind

Cervical cancer treatment just took its biggest leap in 25 years, and the breakthrough comes from a surprisingly simple idea: changing the timing. In a trial spanning the U.K., Mexico, India, Italy, and Brazil, women who received a short course of chemotherapy before standard chemoradiation were 40% less likely to die from the disease. Even better, the drugs involved are already approved, affordable, and widely available — meaning hospitals could adopt this approach without waiting on a new wonder drug. For the hundreds of thousands of women diagnosed each year, especially in lower-income countries where cervical cancer hits hardest, it’s a rare kind of medical good news: a major gain that’s actually within reach.

U.S. announces 10-year deadline to remove all lead pipes nationwide

By / / Good News For Humankind

Lead pipes in roughly nine million American homes are now on a federal clock: the EPA’s new rule requires every utility to find and replace them within 10 years. Backed by $2.6 billion in fresh funding, the policy marks a dramatic shift from previous timelines that stretched 40 or even 50 years out. Nearly half the money is directed to disadvantaged communities, where decades of disinvestment left lead lines in place long after wealthier neighborhoods got upgrades. Milwaukee mother and advocate Deanna Branch, whose son was poisoned by lead, said the shorter timeline finally gives her hope she’ll live to see the pipes pulled from her city. For a country where clean water has long depended on your zip code, a hard deadline is itself a milestone.

Virus up close, for article on lenacapavir HIV prevention

‘Gamechanger’ HIV prevention drug to be made available cheaply in 120 countries

By / / Good News For Humankind

Lenacapavir, a twice-yearly HIV prevention shot with near-perfect results in clinical trials, is about to become far more affordable for millions of people. Gilead Sciences has licensed six generic manufacturers across India, Egypt, Pakistan, and the U.S. to produce the drug for 120 lower-income countries, where researchers estimate it could eventually be made for as little as $40 per patient per year. In trials among cisgender women in South Africa and Uganda, not a single participant who received the injection contracted HIV. Advocates are urging wider access, since much of Latin America was left out of the deal. Still, it’s a hopeful signal that breakthrough prevention tools can reach the people who need them most — fast.

World Health Organization approves first mpox diagnostic test for emergency use

By / / Good News For Humankind

The first mpox diagnostic test has been cleared through the World Health Organization’s Emergency Use Listing, opening a faster procurement route for the countries hit hardest by the outbreak. Abbott’s Alinity m MPXV assay detects both clades of the virus from rash samples, and UN agencies can now order it directly for places where national approval pathways would otherwise take months. That speed matters: in 2024, only 37% of suspected mpox cases in the Democratic Republic of the Congo were confirmed by testing, leaving outbreaks harder to trace. Three more tests are already under WHO review, with more manufacturers in talks. It’s a hopeful signal that the world is learning from past pandemics — building diverse, quality-assured tools before bottlenecks become catastrophes.

Scientists in the U.K. developing world’s first vaccine to prevent ovarian cancer

By / / Good News For Humankind

OvarianVax, in development at the University of Oxford, has just received up to £600,000 from Cancer Research U.K. to pursue the world’s first vaccine designed to prevent ovarian cancer before it begins. The idea is to train the immune system to recognize over 100 proteins found on early-stage ovarian cancer cells, then destroy those cells before they can spread. For women carrying BRCA gene mutations, who currently face the wrenching choice of preventive surgery that ends fertility and triggers early menopause, a vaccine could transform what’s possible. It’s still early days, with lab work and clinical trials ahead, but the project signals a real shift in cancer research: moving from treatment toward prevention, and giving high-risk women better options worldwide.

Chinese researchers reverse type 1 diabetes using a patient’s own stem cells

By / / Good News For Humankind

Type 1 diabetes reversal using a patient’s own stem cells marks a historic milestone in medicine. A 25-year-old woman in China received a transplant of insulin-producing cells reprogrammed from her own body, and within three months was generating insulin naturally — eventually eliminating her need for external injections entirely. Published in Cell in 2024, the research is significant because it bypasses donor tissue and immunosuppressant drugs entirely, dramatically reducing rejection risk. For the roughly 8.4 million people worldwide living with type 1 diabetes, this proof of concept offers a genuinely new direction for treatment.

Jordan becomes first country to receive WHO verification for eliminating leprosy

By / / Good News For Humankind

Leprosy has officially been eliminated in a country for the first time, with the World Health Organization verifying that Jordan has gone more than 20 years without a single locally transmitted case. Reaching that milestone took decades of coordination between Jordan’s Ministry of Health and WHO, plus surveillance systems sharp enough to catch cases arriving from abroad before they could spark local spread. Health leaders are quick to note that this was also a fight against stigma, which has shadowed the disease for millennia. With over 200,000 new cases still diagnosed worldwide each year, mostly in lower-income regions, Jordan offers something the global effort hasn’t had before: living proof that the finish line is reachable.

Global alliance buys half a million mpox vaccines for Africa

By / / Good News For Humankind

Gavi has tapped its emergency First Response Fund for the very first time, committing up to $50 million to send 500,000 mpox vaccines to African countries hit hardest by the outbreak. The fund was built precisely for moments like this — letting the alliance move within days of a health emergency rather than waiting on slower funding cycles. The doses, from manufacturer Bavarian Nordic, will head to places like the Democratic Republic of the Congo, which has carried the heaviest burden of the new Clade 1b strain. It’s a real start, even as experts estimate Africa needs around 10 million doses overall. If the tool keeps getting used and funded, it could reshape how quickly the world responds to outbreaks in lower-income regions.

Nurse practitioners can provide abortions in Alaska, judge rules

By / / Good News For Humankind

Reproductive healthcare in Alaska took a meaningful step forward when a Superior Court ruling allowed nurse practitioners and physician assistants to provide medication abortion, and the change has reshaped daily life at clinics. Planned Parenthood’s Anchorage and Fairbanks locations went from offering abortion services one day a week to every day of the week, a shift that matters enormously in a state where reaching a provider can mean flying hundreds of miles. The Alaska Supreme Court is now weighing whether to reinstate the older physician-only rule, with justices openly questioning how geography shapes what counts as a burden. However the court rules, the case is a powerful reminder that healthcare access depends on who’s allowed to help — and where they live.
