Scientists working for the UN say that they have eradicated a virus which can be deadly to cattle.
If confirmed, rinderpest would become only the second viral disease – after smallpox – to have been eliminated by humans.
Rinderpest was once prevalent in the Middle East, Africa and Asia.
The UN’s Food and Agriculture Organization (FAO) has said that it will now suspend its efforts to track and eliminate the virus.
The FAO said it was "confident" the virus has been eradicated from those parts of the world where it is prevalent.
So the only remaining samples are those owned by governments for experimental weaponization.
