On 30 December, after seeing several patients with flu-like symptoms and resistant to usual treatment methods, Ai received the lab results of one case, which contained the word: “Sars coronavirus.” Ai, reading the report several times, says she broke out into a cold sweat.
She circled the words Sars, took a photo and sent it to a former medical school classmate, now a doctor at another hospital in Wuhan. By that evening, the photo had spread throughout medical circles in Wuhan, where it was also shared by Li Wenliang, becoming the first piece of evidence of the outbreak.
