Expert: Current research and observations have not found that people with new coronary pneumonia recovered are infectious

　　Xinhua News Agency, Wuhan, April 25 (Reporters Yu Jie, Tan Yuanbin) At the routine news conference held on the 25th Hubei Province New Coronary Pneumonia Epidemic Prevention and Control Headquarters, the Director of the Department of Respiratory and Critical Care Medicine, Wuhan University, Central South Hospital, Wuhan Cheng Zhenshun, chairman of the Respiratory Branch of the Medical Association, said that according to current research and clinical observations, no new coronary pneumonia patients were found to be infectious, and society should accept them.

　　This conference focused on the work of rehabilitation services for patients with new coronary pneumonia after discharge.

　　Cheng Zhenshun said that there are four discharge criteria for patients with new coronary pneumonia: the body temperature is more than three days normal; the respiratory symptoms are significantly improved; the lung imaging shows obvious absorption of acute exudative lesions; sputum and nasopharyngeal swabs and other respiratory tract specimens are tested for nucleic acid twice If it is negative, the sampling time should be at least 24 hours apart.

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

　　He also pointed out that during the clinical diagnosis and treatment of new coronary pneumonia, due to the discovery of a "false negative" phenomenon in nucleic acid detection, the national diagnosis and treatment plan was revised to require that after reaching the discharge standard, medical observation at the isolation point should be continued for at least 14 days, and re-check If the nucleic acid is negative, you can return home.

　　"This is equivalent to adding insurance to the original discharge standard, which is rigorous and scientific." Cheng Zhenshun said, therefore, it is safe for them to return to society, whether they are relatives and friends, or people from all walks of life should accept them to return to normal life.
