Background: COVID-19(2019 novel coronavirus disease)has brought tremendous pressure to the prevention and control of the national epidemic due to its concealed onset, strong infectivity and fast transmission speed Methods: In this retrospective study, 226 patients diagnosed with 2019 novel coronavirus pneumonia (NCP) in the Chongqing University Three Gorges Hospital were included The patients' clinical data, including general information, initial symptoms at the onset, time of disease diagnosis, time to treatment in hospital, time of nucleic acid conversion to negative, disease classification, total time of hospitalization were collected The clinical data of the mild and severe patients were compared Results: Fever, cough, sore throat, poor appetite andfatigue were the main symptoms of the diagnosed patients The time of diagnosis was significantly shorter in the mild patients (4 96 ± 4 10 days) than severe patients (7 63 ± 9 17 days) (P=0 004) Mild patients had shorter time to treatment in hospital (6 09 ± 4 47 vs 8 71 ± 9 04 days) and less time of nucleic acid conversion to negative (7 58 ± 2 51 vs 11 6 ± 4 67 days) compared to the severe patients Conclusion: The above results can be used as a quantitative basis for the “five-early"(early detection, early screening, early diagnosis, early isolation treatment, and early recovery) model The government, the masses, and the hospitals' joint prevention and optimization of the "five-early" model will provide important scientific reference for further prevention and control of the epidemics © 2020, Iranian Journal of Public Health All rights reserved

“五早”模式：对抗 COVID-19 的法宝

背景：COVID-19（2019新型冠状病毒病）起病隐蔽、传染性强、传播速度快，给全国疫情防控带来巨大压力 方法：本回顾性研究对2019新型冠状病毒确诊患者226例纳入重庆大学三峡医院肺炎（NCP）患者临床资料，包括一般资料、发病初期症状、疾病诊断时间、入院治疗时间、核酸转阴时间、疾病分类, 收集住院总时间 比较轻症和重症患者的临床资料 结果：发热、咳嗽、喉咙痛、食欲不振和乏力是确诊患者的主要症状轻症患者（4 96±4 10天）的确诊时间明显短于重症患者（7 63±9 17天）（P=0 004）。与重症患者相比，住院治疗时间更短（6 09 ± 4 47 vs 8 71 ± 9 04天），核酸转阴时间更短（7 58 ± 2 51 vs 11 6 ± 4 67天） 结论：上述结果可作为“五早”（早发现、早筛查、早诊断、早隔离治疗、早康复）模式的量化依据 政府、群众、医院联防联控优化“五早”模式将为进一步防控疫情提供重要科学参考 © 2020,伊朗公共卫生杂志 版权所有
