I've worked in facilities management at a university with an infectious disease research program. As with all buildings there were system failures over the years. In one case air filtration failed and it required evacuation. In most countries these incidents would be public, reported in the media and people would move on. But in China it's almost a mandatory requirement that there is a cover-up since any form of 'bad press' is a potent source of destabilisation.
