OBJECTIVES The purpose of this research was to measure fever prevalence and the effectiveness of a fever screening procedure in detecting febrile arrivals at an international airport in Korea.
METHODS
Data were retrieved from arrivals’ health declaration forms and questionnaires for febrile arrivals at an international airport collected by a national quarantine station during the year 2012. Self-reported health declaration forms were returned by 355,887 arrivals (61% of the total arrivals). Of these, 608 symptomatic arrivals (0.2%) including 6 febrile arrivals were analyzed.
RESULTS
Fever prevalence at an international airport in Korea was 0.002%. Self-reported fever was significantly positively associated with tympanic temperature (p<0.001). The difference between the thermal camera temperature (36.83°C) and tympanic (or ear) temperature (38.14°C) was not statistically significant.
CONCLUSIONS
The findings imply that a procedure for mass detection of fever such as self-reported questionnaires and thermal camera scanning may serve as an effective tool for detecting febrile arrivals at quarantine stations. Future research can benefit from looking at the sensitivity, specificity, positive predictive value, and negative predictive value of the entry screening system.
Summary
Korean summary
2003년 전 세계적인 SARS 대 유행 이후, 우리나라는 증상을 자가보고 하도록 하는 검역질문서, 열감지 카메라를 통한 체온 측정, 고막체온 측정 등과 같은 검역절차들이 상호 유기적으로 작용할 수 있도록 검역체계를 강화해 왔다. 그러나 이러한 검역절차들이 얼마나 효과적으로 작용하고 있는지, 그리고 이를 통해 실제로 발열환자가 얼마나 발견되고 있는지에 대한 연구는 전무하였다. 그러한 점에서 본 연구는 이러한 연구 질문에 대한 우리나라 최초의 시도로서, 검역 행정뿐만 아니라 향후 보다 발전된 후속 연구를 위한 기초자료로도 활용될 수 있을 것이다.
