To prevent possible transmission of the virus, no traditional funeral rites or gatherings can be held for patients who die, according to a special regulation issued by the National Health Commission. The remains of those who die must be sterilized and sealed immediately by medical workers. Bodies are transported to the nearest funeral home by a designated route and are cremated on arrival.

Patients who succumb to the virus in isolation wards never get to see their family members before they die, except through video calls, which are sometimes assisted by nurses. This practice has been adopted by Man's team to lift patients' spirits.

"Mental support is crucial for patients' recovery. It helps them get through the difficult times," he said.

Man noted that the number of new infections has slowed, but all 450 beds at the hospital remain occupied. "Asymptomatic patients who are infected could be potential spreaders of the virus. I remain worried about the situation," he added.

Raised in Wuhan, Man said he has never seen the city so deserted.

"Thousands of medical workers have come to Wuhan. We won't resign ourselves to giving up. We need to put the city back on track as soon as possible.

"I'm not a hero. I'm just doing what I'm supposed to do," added Man, who has been a doctor for 23 years.

To date, as a result of the protective measures that have been taken, no staff members in Man's department have been infected by the virus.

He called on the government and various sectors in the country to ensure that sufficient supplies of protective gear reach medical workers "so that we can be more at ease in fighting the 'war'".
