Sleeping sickness: WHO scales-up data management training amid record low cases

10 August 2016 | Geneva –– Over the past 15 years, WHO-supported national control programmes have substantially decreased new cases of human African trypanosomiasis (sleeping sickness) largely through the application of existing control tools.

WHO leads multi-country study to simplify oral treatment of yaws

29 July 2016 | Geneva –– A study in Ghana and Papua New Guinea will determine if a lower dose of the antibiotic, azithromycin, is effective in curing yaws - a chronic skin disease that mainly affects children.
A lower dose is currently being used to treat trachoma, a disease of the eye. If efficacy of a yaws low dose is established, it can be a win-win situation to simultaneously tackle both diseases of poverty.
The researcher who discovered that a single dose of oral azithromycin against yaws recently appealed for free donation of tablets to accelerate eradication of the disease.

India's triumph over yaws adds momentum to global eradication

14 July 2016 | Geneva / New Delhi – WHO has urged countries that remain endemic for yaws to emulate the success of India and accelerate efforts to interrupt transmission by 2020.

India eliminated yaws using injectable penicillin. Today's celebration in New Delhi also marked the success of the country in eliminating maternal and neonatal tetanus as a public health problem.
