World Health Organization Director-General says of the almost 80,000 people who tested positive for COVID-19 in China, more than 70% have recovered and have been discharged from hospitals.

Patients were only released when they tested negative for the virus twice within 24 hours.

Dr. Mike Ryan, W-H-O's emergencies chief, said it can take up to six weeks for people to fully recover from infections related to Coronavirus, which could include pneumonia and other respiratory problems.
