... ompared the characteristics of confirmed cases, including age, occupation, area, symptoms, laboratory results, and computed tomography (CT) scans, by month.Results: By April 30, 4,699 patients had visited the fever outpatient clinic of the SEH; of those, 27 (0.57%) were confirmed COVID-19 cases. Among the confirmed domestic cases identified between January and February, four of five were from Wuhan, Hubei. Following the spread of the epidemic to other parts of the world, all confirmed cases identified in March–April were cases of individuals who were returning from abroad, mainly Chinese students living abroad. Further, all cases were from outside Shanghai, and no local residents were diagnosed in the clinic. Symptoms, laboratory tests, and CT scans were consistent with previous literature reports of positive COVID-19 cases. Conclusions: Given the necessity to control the spread of this epidemic domestically and abroad, the focus of COVID-19 prevention and control has shifted. In Shanghai, measures taken to prevent COVID-19 spread were very successful. Early isolation and quarantine are necessary and effective measures.
