On the same day, Li, who worked at the Central Hospital of Wuhan, received an internal diagnostic report of a suspected severe acute respiratory syndrome (SARS) patient from other doctors, which he in turn shared with his Wuhan University alumni through a WeChat group.

Li was dubbed a whistleblower when that shared report later circulated publicly, despite his messaging to his alumni WeChat group to not spread the message outside of the group with the exception to only “remind their family members and loved ones to be on the alert”. Li did not appear to have intentions of warning the wider public. Rumors of a deadly SARS outbreak subsequently spread on Chinese social media platforms; Wuhan police summoned and admonished him and seven other doctors on 3 January for “making false comments on the Internet about unconfirmed SARS outbreak.”
