Chile becomes the first country in the Americas to eliminate leprosy, WHO verifies

After more than three decades without a locally acquired case, Chile has become just the second country in the world — after Jordan — to be officially verified by the World Health Organization as having eliminated leprosy.
The verification, announced jointly by WHO and the Pan American Health Organization, marks the end of a long arc. Chile’s last locally acquired case was reported in 1993, originating on Rapa Nui (Easter Island), where the disease first arrived in the late 19th century. The win came from decades of patient work: ongoing surveillance, free multidrug treatment provided through PAHO since 1995, trained clinicians, and care that prioritized dignity alongside diagnosis.
Globally, leprosy still affects more than 200,000 people a year, mostly in tropical regions, and WHO has urged Chile to keep its surveillance sharp in case the disease ever returns. But for now, an ancient illness has been pushed to the margins of one country’s medical history — and a model has been built for others to follow.

Tunisian flag, for article on trachoma elimination

Tunisia eliminates trachoma as a public health problem

Trachoma is officially gone as a public health problem in Tunisia — a disease that once affected at least half the country’s population. The World Health Organization has now validated Tunisia as the 31st country to eliminate it, and the first neglected tropical disease ever crossed off the country’s list. The win came from decades of patient work: nationwide screening, eye care woven into schools and clinics, hygiene outreach, and steady improvements in water and sanitation. Around the world, roughly 1.9 million people still live with trachoma-related blindness or visual impairment, and 136 million remain at risk. Tunisia’s story is proof that preventable blindness doesn’t have to stay that way — and a hopeful nudge toward the WHO’s 2030 goal of ending trachoma everywhere.

Two sets of hand holding newborn baby, for article on Coartem Baby malaria treatment

W.H.O. approves world’s first malaria treatment for newborn babies

Newborn babies with malaria finally have a medicine made just for them. Coartem Baby, a cherry-flavored tablet that dissolves into breast milk or water, just earned World Health Organization prequalification — a green light that opens the door to public health systems across sub-Saharan Africa. For decades, doctors had to guess at doses using drugs built for older children, even as research showed infants were getting infected too. Ghana has already begun rolling it out, and Novartis has committed to what it calls “largely not-for-profit pricing” in malaria-endemic regions. Alongside new vaccines and better bed nets, it’s a quiet but meaningful sign that the fight against malaria — which still kills hundreds of thousands of children a year — is reaching the patients it had long overlooked.

HIV up close, for article on mother-to-child HIV transmission

The Bahamas officially eliminates mother-to-child transmission of HIV

The Bahamas just became the 12th country or territory in the Americas certified by the World Health Organization for eliminating mother-to-child HIV transmission — meaning babies born there now enter the world free of the virus by design, not by luck. The country built this through a quietly powerful idea: every pregnant woman, regardless of nationality or legal status, gets HIV screening at her first prenatal visit and again later in pregnancy, with treatment and follow-up offered free. Reaching that standard across more than 700 scattered islands took years of coordination between nurses, doctors, and public clinics. More than half of all places worldwide to achieve this milestone are now in Latin America and the Caribbean — proof that with universal care and political will, this victory is replicable anywhere.

African children smiling, for article on measles vaccination Africa

Nearly 20 million measles deaths averted in Africa since 2000

Measles vaccines in Africa have prevented an estimated 19.5 million deaths since 2000 — roughly 800,000 lives saved every year for nearly a quarter century. A new WHO and Gavi analysis credits steady investment in cold-chain systems, community health workers, and political will, with coverage for the critical second measles dose climbing more than tenfold over that stretch. This year, Cabo Verde, Mauritius, and Seychelles became the first sub-Saharan nations to officially eliminate measles and rubella, a milestone once considered out of reach. The story is a powerful reminder that global health progress, though uneven, compounds quietly over decades — and that protecting children anywhere strengthens the case for protecting them everywhere.

Denmark becomes first E.U. nation to end mother-to-child transmission of HIV and syphilis

Denmark has eliminated mother-to-child transmission of both HIV and syphilis, becoming the first European Union country to receive WHO validation for this dual achievement. Every pregnant person in Denmark receives routine screening for both infections, with treatment integrated directly into antenatal care through a universal health system that removes financial barriers. Left untreated, HIV carries a transmission risk of up to 45 percent during pregnancy and birth, while untreated syphilis causes stillbirth and severe newborn complications. Denmark’s success proves elimination is possible with the right infrastructure and political commitment, even as congenital syphilis rises sharply in countries like the United States.

Humanity eradicates malaria for the first time in recorded history

Malaria eradication could be certified worldwide by 2054, with the WHO confirming zero indigenous transmission across the 80 countries that once carried the disease. The projection builds on real momentum: mRNA vaccine breakthroughs, hundreds of thousands of community health workers, and a 2024 burden concentrated in sub-Saharan Africa. If it holds, a millennia-old killer becomes something only grandparents remember.

Egypt eliminates trachoma, ending millennia of preventable blindness

Egypt has eliminated trachoma as a public health problem, ending a bacterial eye disease that has blinded people in the Nile Valley for more than 3,000 years. The World Health Organization formally validated the achievement, making Egypt the 27th country to reach this milestone. Success came through two decades of coordinated effort combining surgery, antibiotics, hygiene education, and expanded rural sanitation infrastructure. The elimination is significant because Egypt’s scale — over 100 million people across complex rural geography — demonstrates that the WHO’s goal of global trachoma elimination by 2030 is achievable.

Niger becomes first African country free of river blindness

River blindness elimination in Africa has reached a landmark moment: Niger is the first country on the continent declared free of onchocerciasis, following formal World Health Organization verification that transmission of the parasite has been fully interrupted. The achievement closes a cycle of infection that once forced entire communities to abandon fertile river valley land rather than risk permanent blindness. Built on more than 50 years of mass ivermectin distribution, community health networks, and sustained political commitment, Niger’s success proves that elimination targets for neglected tropical diseases are genuinely achievable. The verified milestone also reopens productive agricultural land and signals a realistic path forward for neighboring countries still working toward the same goal.

Cholera vaccination campaign reaches 1.86 million people in Darfur amid active conflict

Sudan cholera vaccination campaign: In late September 2025, health workers delivered oral cholera vaccines to more than 1.86 million people across six localities in the Darfur states, navigating active conflict, broken infrastructure, and collapsed supply chains to reach nearly 97% of the targeted population. Coordinated by Sudan’s Ministry of Health with WHO, UNICEF, and global partners, the campaign addressed an outbreak spanning all 18 states, with over 113,000 cases and 3,000 deaths recorded since July 2024. Beyond vaccination, teams trained local health workers and delivered hygiene education, building lasting community capacity.
