Li Wenliang, a 33 years old Ophthalmologist, who raised alarm on Coronavirus has died of the disease at Wuhan Hospital in China where he was treated on Friday.
Wenliang was fighting Coronavirus which has so far killed more than 600 people and infected tens of thousands.
The doctor had suggested earlier that the disease was a resurgence of severe acute respiratory syndrome (SARS).
Li had told state media that he had been cautioned by hospital management and party officials after alerting his colleagues about a cluster of infections tied to an animal market in the city of Wuhan.
About 600 people have died worldwide from Coronavirus, which has since spread to almost 30 countries.
Nigeria Centre for Disease and Control (NCDC) has advised the public to wash their hands regularly with soap under running water.
