Abstract:
Objective:To analyze the transmissible characteristics of imported COVID-19 cases in Xiamen.Methods:The nasopharyngeal swabs and serum specimens were collected from inbound passengers on the same flight. The nucleic acid and antibodies to SARS-CoV-2 were detected respectively. The type of COVID-19 was determined according to the condition. The mode of transmission was analyzed according to the incidence and laboratory diagnosis of positive cases, and seats of cases on the plane.Results:Five cases of common type, 3 cases of mild type and 1 case of asymptomatic infection were found in the same Russian flight. Three cases, 5 cases, 1 case and 1 case were detected for nucleic acid on November 21, 22, 25 and 26, 2020. The whole genome sequence was obtained in 3 cases and 85% in 1 case. According to epidemiology, evolutionary characteristics of virus genome, Results of qPCR and antibody and case seating, the risk of transmission in aircraft cabin was analyzed.Conclusions:This is COVID-19 cases reports of inbound personnel in aircraft, and there is a risk of transmission in the cabin. The imported cases were isolated timely and effectively with the whole closed-loop. No other cases of infection occurred. This report provides a reference for the detection and prevention of transmission of cases imported by aircraft.
