Medic fights for hospital and husband

"The more people gather in the hospitals, the easier it will be for the virus to spread. It is much better for those with light symptoms to stay at home and self-observe. I really hope people will learn about this and understand it,"Dong said.

By Friday, nearly all the hospitals treating the virus in the city were full or overloaded. With about 6,600 beds, they needed to be ready to accept about 7,000 confirmed cases from across Hubei, along with a growing number of suspected cases.

"Online diagnosis can solve the problem. Doctors can instruct patients how to deal with light symptoms at home to ensure beds are available for those in urgent need. All Wuhan's hospitals need to update their technology; an online system should be set up to inform patients of the number of beds in each hospital," she said.

As director of a department, Dong worries about supplies of protective medical materials every day. Sometimes, she has been unable to sleep until 2 am, which is why she resorted to taking sleeping pills.

"It's like a battle. The virus is like a bullet. We don't know if it will hit us from one day to the next. We lack beds for patients and protective garments for doctors, and we are not sure when we will win this battle," she said.

Although her sons-ages 10 and 4-do not really understand the situation, they have encouraged her to keep holding on.

In a video, her younger son said:"I miss you, Mom. I know you are treating patients, so I will take care of myself and won't let you worry about me. I want to be a doctor in the future. Keep fighting, Wuhan!"

Dong said:"He doesn't know the severity of his father's illness. He is too young. My husband's lungs have been damaged by the virus and he is now being supported by oxygen equipment. I am not sure whether the virus will result in bad consequences or not after his recovery."

On Jan 23, the day before Chinese New Year's Eve, Dong burst into tears as she sat alone at home and the pressure mounted. Since then, she has slept in her office to avoid feeling lonely at home.

"I used to feel secure, because I thought I could fight this together with my husband. But now, he is isolated, leaving me on the battlefield on my own. Now, I just hope that everything will be fine as soon as possible," she said.
