zh-cn	新冠肺炎患者出院后为何需要集中或居家隔离观察两周？ 
en-us	Why do COVID-19 patients need collective or home quarantine for 14 days after being discharged from hospitals? 

zh-cn	根据国家卫生健康委等部门制定的《新型冠状病毒肺炎诊疗方案（试行第七版）》（以下简称《方案》），感染新冠肺炎患者出院标准是体温恢复正常3天以上，呼吸道症状明显好转，肺部影像学显示急性渗出性病变明显改善，连续两次呼吸道病原核酸检测阴性。
en-us	According to the Diagnosis and Treatment Protocol for Coronavirus Pneumonia (Trial Version7) issued by the Chinese National Health Commission (NHC), the discharge criteria for COVID-19 patients are as follows: no fever for more than three days, improved respiratory symptoms, pulmonary imaging showing obvious absorption of inflammation, and 2 consecutive negative nuclei acid test results for respiratory tract samples. 

zh-cn	同时，《方案》建议患者出院后继续进行两周的隔离管理和健康状况监测。 
en-us	The Protocol also recommends that patients continue to undergo quarantine and observe their own health conditions for 14 days. 

zh-cn	新冠肺炎患者出院后需要集中或居家隔离观察两周主要有以下几方面的原因： 
en-us	COVID-19 patients need collective or home quarantine and observation for 14 days after being discharged from hospitals for the following reasons: 

zh-cn	一是部分达到出院标准的患者体内仍然存在少量病毒。
en-us	First, a small amount of coronavirus still exists in some patients who have met the discharge criteria. 

zh-cn	根据目前流行病学观察，当病毒在处于潜伏期时，感染者通常不会表现出相关临床症状。
en-us	In the light of current epidemiological observation, patients infected with the novel coronavirus usually do not show clinical symptoms during the incubation period. 

zh-cn	部分达到出院标准的患者虽然临床症状有明显改善或者消失，但是体内仍可能存在少量病毒，机体仍处于一个病毒清除的康复过程。
en-us	More importantly, although some discharged patients may show significantly-improved or no clinical symptoms, they could still carry a small amount of virus and are in a recovery process of virus clearance. 

zh-cn	出院后继续隔离观察两周，能最大程度地防止“复阳”并控制传染源。 
en-us	With the 14-day quarantine and observation after being discharged from hospitals, the recurrence of positive NCT after the initial recovery and the source of infection can be controlled to the greatest extent. 

zh-cn	二是核酸检测可能会出现“假阴性”的结果。
en-us	Second, nucleic acid tests may appear “false-negative” for people infected with the novel coronavirus. 

zh-cn	由于新冠病毒的自身特点、检测试剂盒的稳定性和标本采集、运输等方面的原因，患者核酸检测可能会出现“假阴性”的情况。
en-us	The test results can be “false-negative” because of such reasons as the characteristics of the novel coronavirus, the stability of coronavirus test kits, and the collection and transportation of samples. 

zh-cn	此类患者隔离观察两周，一旦出现发热、咳嗽等临床表现，可及时转至定点医院进行复诊，避免疾病传播。 
en-us	Through the two-week quarantine and observation, these patients could be transferred to designated hospitals for re-diagnosis in time once the clinical symptoms like fever and cough appear. This also helps cut the transmission of the disease. 

zh-cn	三是避免患者因免疫功能低下感染其他病原体风险。
en-us	Third, two-week collective or home quarantine can reduce the risk of infection with other pathogens due to low immune function. 

zh-cn	患者出院后，机体的免疫功能低下，如果在恢复期内不进行有效的健康管理和检测，可能会有感染其他病原体风险。
en-us	If discharged patients do not undergo effective health management and test during the recovery period, they would be at the risk of infection with other pathogens due to their weakened immune system.
