Manual Fever Check Is More Sensitive than Infrared Thermoscanning Camera for Fever Screening in a Hospital Setting during the COVID-19 Pandemic

Between August 31st and September 4th 2020 in a tertiary care hospital in Seoul, the fever detection rate by infrared thermoscanning camera at the gates was 0.002% (95% confidence interval [CI], 0.001%–0.006%) and that by manual fever check at the outpatient clinics was 0.02% (95% CI, 0.01%–0.03%) (P < 0.001). The difference strongly suggests that sensitivity of the thermoscanning camera in the market must be upgraded.
