Li, according to Chinese media, was found to have been infected with the disease Saturday.
He had been in critical condition, according to the hospital and several state media outlets.
On Dec. 30, Li warned his medical school classmates in an online chat group that a Sars-like illness had stricken several patients in a Wuhan hospital and that all of them were quarantined in the emergency department.
Later that day, local health authorities announced the city had confirmed 27 cases of a new type of virus, most of them linked to a seafood market.
However, Li, along with seven other doctors who shared information about the outbreak, was summoned to the local police and forced to sign a letter promising not to make any further disclosures.

As the coronavirus spreads around the world, so does misinformation.
The World Health Organization declared the outbreak a global public health emergency. Last week, President Donald Trump also declared a public health emergency. In his State of the Union address Tuesday, Trump said the United States was coordinating with China on the response to the outbreak.
