Mr. Ghebreyesus, who was nominated by the Government of Ethiopia and will begin his five-year term on 1 July, was elected Tuesday as the first African to occupy the position.
Dr Tedros said his vision as the new director general was of "a world in which everyone can lead health and productive lives, regardless of who they are or where they live".
The delegates chose Ghebreyesus over U.K.'s Dr. David Nabarro, in the final round of election. Tedros received 133 votes to Nabarro's 50, with two abstentions.

Tedros, 52, was known for having drastically cut deaths from malaria, AIDS, tuberculosis, and neonatal problems when he was Ethiopia's health minister.
Tedros, who campaigned as "Dr. Tedros", is not a medical doctor; he has a Ph.D.in community health.
Still, Tedros' candidacy also drew controversy. He was recently accused of covering up three cholera epidemics in Ethiopia, although there had been no solid evidence of this claim. He vowed to focus on the most needy and noted the importance of effective partnerships with health care providers. "It shows when we are united, we can do everything".
