Q: You said the mortality of severe patient is > 60%. How is the patient that survives the illness. Do they need special care like tracheostomy, feeding tubes, dialysis. In another words how is quality of life?


It is hopeful that the mortality of severe patients will be cut down to less than 50% through strengthening nursing, increasingly effective treatment options and prevention with vaccines. However, in answer to your question, we found that in the patients who survived the illness, their respiratory and renal function returned to baseline as the hypoxia corrected. Of course, in patients with preexisting chronic renal failure there was ongoing need for dialysis. There were a small number of  isolated patient cases with residual pulmonary fibrosis who have had some chronic respiratory insufficiency and needed oxygen treatment occasionally.
