WHO chief Tedros plans to seek second term: report
"Member states may nominate candidates between now and September," the agency said in an email.
"All proposals are sent in sealed envelopes to the Chair of the Executive Board and are strictly confidential until opened in due course," it added.
Tedros was thrust onto the global stage with a number of high-profile health emergencies -- most notably the Covid pandemic, but also several fresh Ebola outbreaks in the Democratic Republic of Congo and in West Africa.
The WHO has found itself at the heart of efforts to coordinate the global pandemic response.
Its handling of the crisis has been widely praised, but has also met harsh criticism from some quarters, and in particular from the administration of former US president Donald Trump.
Trump accused the organisation of being a puppet to China and began withdrawing the United States from the organisation in protest -- a decision immediately rescinded by President Joe Biden when he took office in January.
