Xue, also from Shanxi, is now working at a makeshift hospital in Jiang'an district in Wuhan, capital of Hubei province.

The doctor said he is responsible for circulating operational standards among the doctors covering a range of areas including the use of protective equipment, the layout of inpatient rooms, disinfection, noncontact service and medical waste treatment.

"The medical workers are the most precious wealth in this battle against the coronavirus epidemic, so we must ensure that they can work in safety," Xue said.

"I'm confident we will remain safe by following the strictest protective measures," said Li Shuping, a nurse from Shanxi now working at the Sino-French New Town Hospital in Caidian district of Wuhan.
