A Chinese medical worker died of a heart attack after working 10 days straight to help fight the coronavirus epidemic, according to a report.

Song Yingjie, 28, was found dead Monday in his dorm, following days of working as part of a team to check the temperatures of a checkpoint in Hunan, state media reported, according to the South China Morning Post.

Yingjie — whose normal gig is a hospital pharmacist — had been working since Jan. 25 at the checkpoint, which was on the southern border of the epicenter of the coronavirus outbreak.

“He was very motivated, hard-working, and he never complained,” Yang Dan, who worked with Song at the hospital, told local media.

Song’s death comes as the country works to contain the coronavirus, which has killed 563 people in mainland China.
