When Sri Lanka declared itself free of malaria in 2016 C.E., it did something few thought possible for a tropical island nation still recovering from decades of civil conflict. It became a model — and a warning — for the rest of the world at once.
What the evidence shows
- Malaria elimination: Sri Lanka met the World Health Organization’s criterion of three consecutive years without a single locally transmitted infection, earning its malaria-free certification in 2016 C.E.
- Global malaria progress: Between 2000 C.E. and 2015 C.E., new malaria cases worldwide dropped by 37% and death rates fell by 60%, including a 65% decline among children under five.
- WHO elimination targets: A WHO list published in April 2016 C.E. identified 21 countries — including China, Malaysia, Iran, and South Africa — as candidates to eliminate malaria by the end of the decade.
How Sri Lanka did it
Sri Lanka’s approach was not simply a matter of handing out mosquito nets and waiting. The government targeted the malaria parasite directly, knowing it could never fully eliminate the Anopheles culicifacies mosquitoes that live in the island’s jungle regions.
Mobile clinics reached the most remote and worst-affected communities. Quick diagnosis of malaria in children meant treatment could begin before mosquitoes had a chance to pick up the parasite from infected blood and carry it to the next person. Public education campaigns ran alongside the clinical work.
More than 80% of Sri Lanka’s 22 million people live in rural areas — precisely the environments where malaria transmission thrives. Working against that geography required sustained political will over many years, not just a short-term health campaign.
“The country took ownership of the problem themselves,” said Dr. Pedro Alonso, director of the WHO’s Global Malaria Programme. “They wanted to eliminate malaria even in the face of the civil unrest they had in the last decade. They paid for it themselves.”
That self-funded commitment drew in additional international support, including from the Global Fund to Fight AIDS, Tuberculosis and Malaria. But the drive came from within.
The weight of history
Sri Lanka’s victory carries a particular resonance because the island has been here before — and lost.
In 1963 C.E., malaria cases had fallen from two million a year to just 17. It looked like the disease was done. But when control efforts wound down, the parasite surged back. By 1998 C.E., Sri Lanka was recording more than 250,000 cases annually.
That collapse was part of a broader global story. The WHO’s first malaria eradication campaign, launched in 1955 C.E., made rapid progress using the pesticide DDT and the drug chloroquine, pushing malaria out of parts of the Americas, Europe, and Asia. But it excluded sub-Saharan Africa as too difficult, failed to address drug and pesticide resistance, and collapsed entirely after Rachel Carson’s 1962 C.E. book Silent Spring exposed DDT’s environmental toll. The eradication program was formally abandoned in 1969 C.E.
“In the world of malaria, Sri Lanka carries a special weight,” Alonso said. “It is often cited as the example of what happened during the first malaria eradication programme. They didn’t complete the job and malaria came back with a vengeance. We need to learn from the past so we don’t repeat the mistakes.”
Lasting impact
Sri Lanka’s 2016 C.E. certification matters beyond one island. It arrived alongside a broader wave of momentum. As of that year, 13 countries — including Argentina and Turkey — had already gone at least a year without a recorded case. The WHO’s list of 21 potential eliminator nations by 2020 C.E. included countries across Asia, Latin America, the Middle East, and southern Africa.
In 2015 C.E., the United Nations and the Bill & Melinda Gates Foundation released a joint plan to eradicate malaria worldwide by 2040 C.E. — not just eliminate it country by country, but end it entirely. That goal was not considered outrageous; it was considered achievable, if the tools, funding, and political commitment could all be sustained.
Sri Lanka’s story shows what “political commitment” actually looks like in practice: mobile clinics in jungles, fast diagnosis in children, a national government that funds its own health infrastructure rather than waiting for foreign aid to arrive first.
Blindspots and limits
The path from elimination to eradication remains long and uneven. Sub-Saharan Africa continues to bear the heaviest burden — the Democratic Republic of the Congo and Nigeria alone account for more than 40% of all malaria deaths globally. Tanzania, Uganda, Mozambique, and Côte d’Ivoire face similarly severe challenges. The malaria parasite is also developing resistance to artemisinin, the best available drug, while the first malaria vaccine approved for widespread use offers only partial protection. History is clear that premature celebration is one of malaria’s oldest enemies.

Renewables hit 49% of global power capacity for the first time
Renewable energy capacity crossed a landmark threshold in 2025, with global installed power surpassing 5,100 gigawatts and representing 49% of all capacity worldwide for the first time in history. The International Renewable Energy Agency reported a single-year addition of 692 gigawatts, led overwhelmingly by solar power, which alone accounted for 75% of new renewable installations. Clean energy now represents 85.6% of all new power capacity added globally, signaling that the transition has moved from aspiration to economic reality. The milestone carries implications beyond climate — nations with strong renewable bases demonstrated measurably greater energy security amid ongoing geopolitical instability.

Global suicide rate has dropped nearly 40% since the 1990s
Global suicide rates have dropped nearly 40% since the early 1990s, falling from roughly 15 deaths per 100,000 people to around nine — one of modern public health’s most significant and underreported victories. This decline was driven by expanded mental health services, crisis intervention programs, and proven strategies like restricting access to lethal means. The progress spans dozens of countries, with especially sharp declines in East Asia and Europe. Critically, this trend demonstrates that suicide is preventable at a population level — making the case for sustained investment in mental health infrastructure worldwide.

Rhinos return to Uganda’s wild after 43 years of absence
Uganda rhino reintroduction marks a historic milestone: wild rhinoceroses are roaming Ugandan soil for the first time in over 40 years. In 2026, rhinos bred at Ziwa Rhino Sanctuary were released into Kidepo Valley National Park, ending an absence caused entirely by poaching and political collapse during the Idi Amin era. The release represents decades of careful breeding, conservation funding, and community engagement. For local communities, conservationists, and a watching world, it proves that deliberate, sustained human effort can reverse even the most painful wildlife losses.
