早发现、早报告、早隔离、早治疗
“早发现、早报告、早隔离、早治疗”是中央对防控新冠肺炎疫情提出的明确要求，也是中国科学防治新冠肺炎的一项重要措施。2020年 1月20日，国家卫生健康委高级别专家组研判指出，在疫情上升期，早发现、早隔离是最有效的防控手段，要尽可能减少传播。1月25日中共中央政治局常委会召开专题会议，要求做好疫情监测、排查、预警等工作，切实做到早发现、早报告、早隔离、早治疗。
随着疫情防控进入关键阶段，国务院应对新冠肺炎疫情联防联控机制印发《关于进一步强化责任落实 做好防治工作的通知》，对防控措施作出具体要求：及早发现和隔离病毒感染者，有效阻断疫情扩散蔓延；前移疫情防控关口，加强社区网格化管理，将各项防控措施抓早抓小、落细落实；进一步提高检测能力，优化确诊程序、缩短确诊时间，实行边诊边治。2月23日，习近平在统筹推进新冠肺炎疫情防控和经济社会发展工作部署会议上发表重要讲话，明确早发现、早报告、早隔离、早治疗的防控要求，强调要坚决遏制疫情扩散输出，对确诊患者应收尽收，对疑似患者应检尽检，对密切接触者应隔尽隔，落实“四早”要求，找到管好每一个风险环节，决不能留下任何死角和空白。
随着“早发现、早报告、早隔离、早治疗”措施逐渐显效，疫情蔓延势头得到初步遏制，防控工作取得阶段性成效。
Early Detection, Reporting, Isolation and Treatment
"Early detection, reporting, isolation and treatment" is a definite principle put forward by the central leadership for epidemic prevention and control, and it is also an important measure taken by the country to fight the virus.
On January 20, 2020, the High-level Expert Group of the NHC pointed out that against the rapid escalation of the virus, early detection and early isolation are the most effective means to block it and keep transmission to a minimum. The Standing Committee of the Political Bureau of the CPC Central Committee on January 25 demanded monitoring, screening and early warning be conducted to ensure early detection, reporting, isolation and treatment.
As epidemic prevention and control entered a critical stage, the Joint Prevention and Control Mechanism of the State Council on February 7 issued a document on the responsibilities of different parties during epidemic prevention and control. The document emphasized the urgency of early detection and early isolation of infected people to effectively prevent the transmission of the virus. For this end, it is necessary to deploy preventive methods at an early stage and perform meticulous community grid management. It is also necessary to further improve the testing capability, optimize the diagnostic process, shorten diagnosis time, and carry out diagnosis and treatment simultaneously.
At the national meeting for coordinating China's epidemic control and economic and social development, held on February 23, Xi Jinping reiterated the principle of early detection, reporting, isolation and treatment. He urged more efforts to resolutely curb the spread of the epidemic, hospitalize all confirmed patients, conduct thorough tests of all suspected patients, and isolate all those close contacts. He demanded tracking and managing every potential risk without leaving any dead corners.
With the efforts made in "early detection, reporting, isolation and treatment," the spread of the epidemic has been initially curbed, and phased effects have been achieved in the prevention and control of the epidemic.
