The death toll thereby surpassed that of SARS, a respiratory disease which caused a global health scare in the early 2000, and which also began in China.
Across China, 89 new deaths and 2,656 new confirmed cases were reported, the vast majority in the province of Hubei.
According to the commission’s figures, health authorities recorded a total of 33,738 confirmed cases of the new coronavirus since the beginning of the outbreak in December.
The outbreak’s epicentre is located in the city of Wuhan in Hubei province.
There, the number of new cases of pneumonia caused by the virus rose by 2,147, the provincial health commission said.
Also 81 new deaths were reported over the last 24 hours in Hubei, bringing the total to 780.
The virus, which has spread to about two dozen countries since first being identified, has only claimed the lives of two people outside mainland China, a Chinese man in the Philippines and a man in Hong Kong.
Both victims had been to Hubei.
The coronavirus broke out at a seafood market in Wuhan that reportedly sold exotic animals for consumption – similar to the outbreak of SARS.
SARS infected 8,000 people and killed 800 globally between 2002 and 2003.
It was linked to the consumption of civet cats, another exotic meat.
The coronavirus belongs to the same family of viruses.
