Guinea worm disease nears total eradication with just 10 human cases recorded

Guinea worm disease is on the verge of becoming only the second human disease ever eradicated, after confirmed cases fell to a historic low of just 10 worldwide. This ancient parasite, which has tormented humans for millennia, has been reduced by more than 99.9 percent since the 1980s through an extraordinary public health campaign relying entirely on community education, water filtration, and local surveillance — no vaccine or drug exists. The achievement, led largely by the Carter Center and local health workers across sub-Saharan Africa, demonstrates that sustained, community-driven effort can conquer even the oldest and most entrenched diseases.

South Sudan launches epic effort to protect the world’s largest mammal migration

South Sudan’s great migration — now confirmed as the largest land mammal movement on Earth — sweeps up to six million animals across the floodplains each year, following rainfall in a vast circular loop. A new 10-year partnership between the South Sudanese government and the nonprofit African Parks is working to keep it that way, blending aerial surveys and GPS collars with generations of Indigenous knowledge. Seventeen ethnic groups share this landscape, and for centuries they’ve left informal corridors of “No Man’s Land” open so wildlife can pass freely between them. Tribal members now serve as observers, technicians, and field operators in the conservation effort itself. It’s a hopeful reminder that the most enduring protection often grows from the people who’ve always lived alongside what they’re protecting.
