Shanghai medical teams aiding Wuhan

Xin Haiguang, from Ruijin Hospital's Infectious Disease Department, said his team of doctors and nurses are going the "extra mile" in their work in Wuhan, as all 26 patients they are responsible for are in critical condition.

"Many of the patients are elderly and have medical complications, including kidney failure, Alzheimer's and Parkinson's disease, and most are finding it difficult to breathe," said Xin, who was among the Chinese doctors sent to Africa to battle the Ebola outbreak five years ago.
