There have been calls to revamp the UN health agency as well as the entire global approach to health to avoid future catastrophes.
A WHO committee tasked with verifying country delegation credentials had proposed deferring a decision on who should represent Myanmar at the key meeting, "pending guidance from the United Nations General Assembly" on how the UN system as a whole should view the matter.
For now, that would mean "no one would represent Myanmar at the Seventy-fourth World Health Assembly", according to the proposal, which was approved by WHO member states without a vote Wednesday morning.
Myanmar has been in turmoil since the 1 February putsch, which has sparked near-daily protests and a nationwide civil disobedience movement.
The military has killed more than 800 civilians in a crackdown on dissent, according to a local monitoring group.
