Dr Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization, has renewed the appointment of Michael R. Bloomberg as WHO Global Ambassador for Noncommunicable diseases (NCDs) and Injuries, as world leaders meet at the United Nations in New York to agree steps to better address NCDs, the world’s biggest killers. “I am delighted that Mike Bloomberg has agreed to continue in his role as WHO Global Ambassador,” said Dr Tedros. “He has had tremendous impact in that role over the past two years. I want to particularly thank him for launching the Partnership for Healthy Cities - so far 50 cities have signed up to the network, committing to protecting their populations from NCDs.”
