Abstract

Abstract

Objective To analyze the epidemiological characteristics of coronavirus disease 2019 (COVID-19) in a family cluster after a patient was discharged from hospital, and to provide recommendations for prevention and control of familial aggregation of COVID-19. Methods On-site epidemiological investigation was conducted to collect personal information, exposure history, morbidity, and clinical information of the COVID-19 patients and close contacts. Based on the data, the source of the COVID-19 virus and transmission mode were further analyzed. Results There were 3 cases and 1 person tested positive for nucleic acid of the virus in the familial aggregation of COVID-19 infection. The most likely source of infection came from hospital exposure and subsequent transmission among family members. Case C, as the first case, maybe a deceptive cure when she was discharged from hospital. The time of recurrence in the family might be much earlier than the reported time of symptom onset. No evidence was found to support the spread of COVID-19 after her discharge. Conclusions It is recommended to strengthen epidemiological investigation, comprehensively analyze clinical and laboratory results, quarantine close contacts of COVID-19 confirmed cases for medical observation, and carry out terminal disinfection of patients' households.
