This is a critical time in the new coronavirus pneumonia outbreak, with no definitive conclusions on the origin of the virus, and the final diagnosis of whether or not it is related to any type of wildlife is still being made. For the after-effects, the final conclusion is yet to be gradually refined. Professor Zhan Qingyuan of the China-Japan Friendship Hospital Lung Disease Prevention and Control Expert Group said at a press conference held on January 30th that the new coronavirus infection mainly affects the lungs, and there are generally no sequelae in patients with mild illnesses, and for patients with severe illnesses, there may be residual lung damage such as pulmonary fibrosis for a period of time, but because the lungs have a strong ability to repair, they can generally be repaired. However, in extremely severe patients, fibrosis may remain for a longer period of time, and follow-up and treatment should be strengthened at a later stage. Content source: Dr. Yurai
