This conference focuses on novel coronavirus pneumonia discharged patients after recovery service related work.

Cheng Zhenshun said that the novel coronavirus pneumonia patients discharge standard has four: the body temperature is normal for more than three days; the respiratory symptom obviously improves; the lung imageology shows that the acute exudation pathological change obviously absorbs; the breath and so on sputum, the nasopharynx swab and so on two times nucleic acid test is negative, sampling time interval is at least 24 hours.

"This discharge standard not only conforms to the treatment principle of pneumonia, but also meets the management requirements of respiratory infectious diseases." Cheng Zhenshun said.
