title: A compact and hand-held infection-screening system for use in rapid medical inspection at airport quarantine stations: system design and preliminary validation.
abstract: To conduct mass screening and thereby reduce the spread of infection, a compact (13.5 cm × 8.5 cm × 2.5 cm), highly-mobile and hand-held infection-screening system was developed for rapid medical inspection in mass gathering places such as airports. The system is capable of non-contact vital-sign monitoring using two integrated sensors: a 24-GHz microwave radar for measuring heart and respiration rates and a thermopile array for capturing facial temperature. Subsequently, the system detects infected individuals using a linear discriminant function (LDA) from the derived vital-signs data. The system was tested on 10 subjects under two conditions (resting as normal and exercising as pseudo-infected, i.e. a 10-min bicycle ergometer at 100 W exercise); the normal and pseudo-infected conditions were classified successfully via LDA for all subjects (p < 0.01; classification error rate < 5%). The proposed non-contact system can be applied for preventing secondary exposure of medical doctors at the outbreak of highly pathogenic infectious diseases such as the Ebola virus.
