"Nearly two thirds of these cases were reported in just four countries", said Ghebreyesus on Wednesday.
More than 4.9 million cases of the novel coronavirus have been registered in total since the outbreak first emerged in China last December, according to a tally from official sources compiled by AFP.
At a time when the WHO should be fully resourced and charged up to lead the world out of COVID-19, there is controversy which could cause a weakening of the organisation and loss of financial support. On Wednesday, Brazil saw almost 20,000 new infections in 24 hours bringing its grand total to 233,140 cases, the third-highest number of national cases in the world, according to data collated by Johns Hopkins University.
"The landmark resolution underlines WHO's key role in promoting access to safe, effective health technologies to fight the pandemic", said WHO Director-General Tedros Ghebreyesus.
The Assembly discussed lessons, challenges and collective next steps to tackle the pandemic.
At the assembly, World Health Organization expressed concern about the rising numbers of cases in low- and middle-income countries. Health is not a cost.
As the world continues to battle COVID-19, Ghebreyesus called on governments to ensure that health systems continue to function to avoid the risk brought on by the suspension of essential services, like child immunisation. "It's the smart choice".
At the conference, Tedros anticipated countries will have to manage their activity around the coronavirus for the foreseeable future, with some experiencing a decline in the number of infections while in others the virus will resurge.
The WHA resolution bucked a trend that has seen China and the USA butt heads at recent worldwide summits over various stipulations in proposed multilateral agreements, in several cases resulting in no final recommendations being made.
Anchor: Instead of taking part in the latest World Health Organization's annual assembly, U.S. President Donald Trump recently sent a letter to the United Nations health agency, threatening to halt funding and sever its membership.
The United States is the biggest contributor to the WHO's budget and has already suspended funding, accusing the organisation of severely mismanaging and covering up the spread of the virus.
Reporters showered him with questions over the letter, but Tedros did not elaborate.
Tedros has always promised a post-pandemic review and "accountability".
"I said it time and time again that World Health Organization calls for accountability more than anyone".
"The draft resolution proposes to initiate at the appropriate moment an evaluation rather than to launch an 'independent global review, '" Zhao said. Peru, Mexico and Chile have also seen steady increases in infections.
