This is the same forum and possibly even the same day when they're scaremongering their next fake 'Disease X' scenario, with Tedros in attendance as speaker. Getting a smelly breathed shaman to cough in everyone's faces while they smirk about it is probably just their way of having a knowing laugh with eachother, a reassurance that nothing they talk about is meant to apply to them, and part of the global humiliation ritual for anyone outside who gets a glimpse.
