ABSTRACT
Objective To analyze the transmission characteristics of family clustering of Corona Virus Disease 2019 (COVID-19) in a town in Tianjin, and to study new epidemiological investigation method applied for the epidemic. Methods The field epidemiological method was applied to investigate confirmed, suspected cases and close contacts of COVID-19, and this clustering epidemic was analyze;and real-time fluorescence PCR (RT-PCR) assay was used for 2019-nCoV nucleic acid testing. Results A total of 11 confirmed cases and 1 suspected case, with three generations of transmission and median generation interval of 6 (2-26) days were involved in current clustering epidemic, the confirmed cases were infectious at the end of the incubation period, the recurrence rate within the families was 33. 33% (19/57), and the epidemiological investigation information acquired through case narration were deviated compared with the trace investigated by police force and the information provided by close contacts. Conclusion The COVID-19 can cause the family clustering spread, and it may infectious at the end of the incubation period. It is necessary to strengthen the trace and management of close contacts during clustering epidemics, and multiple methods adopted making for acquiring epidemiological investigation information. © 2022, Editorial Department of Medical Pest Control.
