摘　　要：【目的】了解上海市青浦区新型冠状病毒肺炎(新冠肺炎)疫情的流行病学特征,为新冠肺炎防控提供依据。【方法】以青浦区医疗机构发现的新冠肺炎疑似病例为研究对象,描述性分析其发病就诊、临床表现、可疑暴露情况等特征。【结果】青浦区共报告53例新冠肺炎疑似病例,其中排除47例,确诊6例。6例确诊病例中自主发病就医的2例,其他方式发现4例;男性占83.3%;首发症状以咳嗽为主;成人病例中有基础性疾病者占75.0%;输入性病例占66.7%。新型冠状病毒核酸检测痰液均为阳性,鼻拭子阳性占50.0%,咽拭子均为阴性。【结论】青浦区新冠肺炎病例男性多于女性。痰标本新型冠状病毒阳性率高于鼻拭子,鼻拭子的阳性率高于咽拭子。将预防关口前移,加强道口监测、来沪人员居家或集中健康观察,第一时间发现疑似病例是新冠肺炎疫情防控的关键。[Objective]To analyze epidemic characteristics of COVID-19 epidemic in Qingpu District of Shanghai and provide evidence for prevention and control of COVID-19.[Methods]The COVID-19 cases diagnosed in the medical facilities in Qingpu District were included in the study.Descriptive epidemiology was employed to describe diagnosis,clinical symptoms and possible exposure.[Results]There were 53 suspected cases identified in Qingpu District,47 of which were excluded and 6 were confirmed.Two confirmed cases were identified when seeking medical treatment and 4 by other means.Of the confirmed cases,83.3%were male and 66.7%were imported.Their initial symptom was mainly cough.The 75.0%of the confirmed cases had underlying diseases.By PCR testing of SARS-CoV-2,100.0%of the sputum specimens tested positive,50.0%of the nasopharyngeal swabs were positive,whereas 100.0%of the throat swabs were negative.[Conclusion]COVID-19 is more common in men than in women.The positive rate of SARS-CoV-2 in sputum samples is highest,followed by nasopharyngeal swabs and throat swabs.It is crucial to implement the countermeasures at earlier stages,such as strengthening the road entrance monitoring,at-home or intensive health observation of foreign visitors for early identification of suspected COVID-19 cases.
