Patient zero was a virologist that seems to have been censored off the Chinese internet afterwards, and I can't find the links anymore :-/
In the beginning of sars-cov-2 breakout there was an article shared on wechat that later got censored in varying degrees of translations/"hacks" to avoid censorships, they wrote it in emojis and stuff to trick the censorship algorithm. All of them were referencing Ai Fen's video and photo of the diagnostics report of patient zero that she recorded and spread on WeChat to warn others.
Maybe someone else has an archive link or screenshots or anything. Impossible to google the source due to the apparent emoji noise.
