In patients with novel coronavirus pneumonia, the main clinical symptoms are fever, cough, malaise, and in a few heavy patients, headache, muscle and joint pain, dyspnea, shortness of breath, especially after activity, shortness of breath, wheezing and chest tightness. When entering the recovery period, usually from the onset of 10 days after the onset of the disease, ordinary, light patients begin to enter the recovery period, the earliest manifestation is the reduction of coughing symptoms, body temperature also began to decline, back to normal. The doctor will arrange for a chest CT. If the chest CT is also improving, and the patient feels that his/her strength has returned and he/she does not have shortness of breath after moving around, that is a sign of improvement. The seventh edition of the treatment plan now stipulates the following criteria for discharge: 1) the patient feels that his/her symptoms have significantly improved; 2) his/her body temperature has been normalized for more than 3 days; 3) he/she has two negative nucleic acid tests, and the two tests are more than 24 hours apart; 4) the chest CT shows that the chest exudate has significantly improved.
