Issue Date: | 22-Jun-2020 | Source: | JAMA network open, 22 June 2020, v. 3, no. 6, e2012934 | Abstract: | Importance: A new outbreak of pneumonia caused by severe acute respiratory syndrome coronavirus 2 in Wuhan, China, is spreading rapidly around the globe. Limited information on control in community settings is available. Objective: To detail measures enacted within a community to prevent the spread of coronavirus disease 2019 (COVID-19) and to evaluate the spread of COVID-19 associated with implementation of the program. Design, Setting, and Participants: This case series study details the implementation of prevention measures in a specific community setting among community-dwelling individuals exposed to or at risk of COVID-19 in Haiyu, Shenzhen, China, from January 23 to April 10, 2020. Exposures: Community containment strategies for tracking, quarantine, and management were strictly, cooperatively, and effectively implemented by a team that included a general practitioner, a community manager, and public safety bureau officials. Main Outcomes and Measures: Number of locally acquired cases with indirect links to confirmed COVID-19 cases. Diagnosis with COVID-19 was confirmed when throat swab samples tested positive for severe acute respiratory syndrome coronavirus 2 on reverse transcription-polymerase chain reaction. Results: Approximately 34 686 individuals live in Haiyu, including 2382 residents aged 65 years or older. Seven individuals with COVID-19 acquired outside the community (age, 20-70 years; 3 [42%] women) were moved from quarantine to a hospital for standard isolation treatment. A total of 20 people who were asymptomatic and who had had direct contact with these individuals were closely observed by health care workers at a nearby hotel. Additionally, 800 individuals considered to be at higher risk were moved from quarantine to home isolation for 14 days. There were no locally acquired cases of COVID-19 with indirect links reported in the Haiyu community from the time that the study began on January 23, 2020, to April 10, 2020. Conclusions and Relevance: These findings suggest that cooperation among the authorities of multiple sectors allowed for the implementation of preventive measures that were associated with limited community transmission. | Publisher: | American Medical Association | Journal: | JAMA network open | ISSN: | 2574-3805 | DOI: | 10.1001/jamanetworkopen.2020.12934 | Rights: | This is an open access article distributed under the terms of the CC-BY License (https://jamanetwork.com/journals/jamanetworkopen/pages/instructions-for-authors#SecOpenAccess). © 2020 Zhang X-M et al.
