WHO director general Dr Tedros Adhanom Ghebreyesus led tribute to Mr O’Leary – describing him as an “outstanding humanitarian”.
“He served tirelessly in the most difficult parts of the world, to help the most vulnerable populations survive and thrive and to end polio,” he said.
“He embodied the ideal of service and solidarity across peoples and borders. His passing is a terrible loss for WHO, for the UN and for all of humanity.”
