For the first time in history, a country has been officially verified as having eliminated leprosy. The World Health Organization confirmed that Jordan has met the threshold, marking a milestone that public health officials say could reshape how the world approaches one of its oldest known diseases.
At a glance
- Leprosy elimination: Jordan has not reported a single locally transmitted case of leprosy in over two decades, prompting WHO to commission an independent verification team to review the evidence.
- Hansen’s disease: Caused by the bacterium Mycobacterium leprae, this chronic infection affects the skin, peripheral nerves, and eyes — and can cause permanent disability if left untreated.
- WHO verification: After an extensive independent review, the team recommended WHO formally acknowledge Jordan’s elimination status, making Jordan the first country in the world to receive this designation.
What elimination actually means
Leprosy still affects more than 120 countries worldwide. Over 200,000 new cases are reported every year, mostly in South Asia, sub-Saharan Africa, and parts of Latin America. Against that backdrop, Jordan’s achievement stands out sharply.
Elimination, in WHO terms, means the interruption of local transmission — no new cases originating within the country. Jordan crossed that threshold more than 20 years ago and has maintained it since. The verification process required an independent team to confirm the data, assess surveillance systems, and review public health infrastructure before WHO could officially make the call.
That rigor matters. The designation is not symbolic — it reflects a sustained, system-level commitment rather than a lucky gap in reporting.
Decades of sustained effort
Jordan’s success did not happen quickly. It required consistent political will, strong coordination between the Ministry of Health and WHO, and surveillance systems capable of catching cases — including those originating abroad — before any local chain of transmission could begin.
WHO Director-General Dr. Tedros Adhanom Ghebreyesus noted that leprosy has “afflicted humanity for millennia,” and that progress is only coming country by country, through exactly this kind of deliberate, long-term effort. Saima Wazed, WHO Regional Director for South-East Asia and head of the Global Leprosy Programme, framed the fight as more than medical: “It is also a fight against stigma, and a fight against psychological and socio-economic harm.”
That framing reflects something important about leprosy’s history. The disease has carried severe social stigma for thousands of years, leading to isolation, discrimination, and shame for those diagnosed. Eliminating transmission also means dismantling the conditions that made that stigma possible in the first place.
A model for other countries
WHO Regional Director for the Eastern Mediterranean Dr. Hanan Balkhy said Jordan’s status as the first verified country “will transform the discourse around this age-old, stigmatizing disease” and serve as an inspiration to other nations still working toward elimination.
The precedent matters in practical terms. Jordan has demonstrated that a country with limited resources — and in a region that has faced significant public health challenges — can reach and hold this threshold through coordination, surveillance, and commitment. That model is replicable.
WHO Representative to Jordan Dr. Jamela Al-Raiby pointed to the partnership between the Ministry of Health and WHO at all three organizational levels — country, regional, and global — as a key factor in making this work. That kind of multi-level collaboration is exactly the architecture needed to take leprosy elimination global.
The work that remains
Both WHO and Jordan’s Ministry of Health are clear that verification is not the end of the road. Robust surveillance systems must stay in place to detect and manage any future cases, including those that might arrive from abroad. As long as leprosy persists in other countries, the risk of importation remains real — and the response to any such case must be swift and non-discriminatory.
More than 200,000 new leprosy cases are still diagnosed globally each year, and the burden falls disproportionately on some of the world’s poorest communities. Jordan’s achievement is meaningful, but the global picture is still far from resolved.
Still, the direction is clear. Early diagnosis and treatment can prevent the disabilities that made leprosy so feared for so long. And now, for the first time, the world has proof that a country can reach the finish line.

More than 50 nations attend world-first conference on phasing out fossil fuels
Fossil fuel phaseout talks just crossed a real threshold: for the first time, more than 50 nations sat down together specifically to plan a way off coal, oil, and gas. The two-day gathering in Santa Marta, Colombia, brought together an unusually wide mix — major producers like Australia, Norway, and Canada alongside Pacific island nations like Tuvalu and Vanuatu, with Europe and emerging economies in between. No binding deals were expected, but the recommendations will feed into a voluntary roadmap being shaped under Brazil’s COP30 leadership. It’s a small, hopeful shift: producers and consumers finally talking openly about a transition…

Singapore stops sourcing and breeding dolphins
Resorts World Sentosa, home to more than 20 Indo-Pacific bottlenose dolphins, is halting both wild sourcing and captive breeding at its Singapore oceanarium. The resort is now assembling an independent expert panel to figure out what’s next for the animals in its care, including a 7-year-old named Kenzo. It’s a meaningful shift from one of Asia’s most prominent entertainment venues, and one animal welfare groups have pushed toward for over a decade. With Mexico, Canada, and France already banning cetacean captivity for entertainment, this quiet decision in Singapore signals that the tide is turning across Asia too, reshaping what travelers…

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…
