Li Wenliang was a Chinese ophthalmologist at Wuhan Central Hospital who warned about COVID-19 on 30 December 2019 on WeChat to fellow colleagues, becoming a whistleblower when his warnings were later shared publicly. On 3 January 2020, Wuhan police summoned and admonished him for "making false comments on the Internet". Li returned to work, later contracting the virus from an infected patient and dying from the disease on 7 February 2020.
